Sensor Controlled Relay
Configure Trigger Points Wirelessly
Once Configured the Computer is No Longer Needed!
Board Triggers Relay Based on Configured Sensor Points
The Reactor controller must be configured using a computer and the included Base Station Software. Once configured, a Reactor will operate without a computer. By choosing the 802.15.4 wireless version you will communicate to the board wirelessly through a modem connected to the USB port of your computer. The wireless option is perfect for applications where the board may be mounted where it's difficult to reach. Wireless will allow you to access the board to make configuration changes or to take manual control of the board.
Take Manual Control of Reactor
At any time, a computer may monitor the Reactor, trigger events, activate relays, or change configuration settings. This wireless version will allow easy access to the board even if it's installed in an out of the way location. A computer can take over a Reactor or a Reactor can operate autonomously (without a computer). The Reactor Configuration Utility (part of Base Station) provides over 100 pre-set configurations that will help you understand the capabilities of the Reactor and provide you a starting point for your own application.
About 802.15.4 Wireless
802.15.4 is not one of the most widely known wireless technologies but it is easy to setup and use, and vey reliable. You will need a 802.15.4 modem that plugs into your USB port of your computer to talk any number of 802.15.4 relays with a standard range of 300' and up to 1 mile. You can choose the distance of the module installed at checkout.!
802.15.4 Wireless Modules
This board is equipped with a 802.15.4 Module. The 802.15.4 communications module adds wireless communications to the board. The 802.15.4 module is powered from the board. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type transformer at checkout. Click the following link for a spec sheet on the XBeeŽ Multipoint RF Modules
As with any wireless technologies, for optimal performance it needs to be line-of-sight. In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all. Select the External Antenna option to provide better range especially when controller will be mounted in an enclosure or behind a wall or obstruction.
External Antenna Option
The External Antenna option is available with the 300' and 1-mile range modules and has a short pig tail that connects to a button on the 802.15.4 external module. Please note that the internal antenna modules (shown above) have antennas that are about an inch long and integrated into the module. The external antenna cannot be used on an internal antenna module or added after purchase. Prices shown are with the 300' internal antenna option.
802.15.4 Wireless Modem
Plug the XBP24-AUI-EXT_ZIGMO modem into the USB Port of your computer. The modem will mount as a COM port on your PC. Open the COM port and start sending data to the modem. The modem will forward your data to all Wireless 802.15.4 compliant devices within range (it is also possible to speak to a specific device when other controllers are in range). Mounting slots on the modem make it easy to attach to a wall to allow for line-of-site operation. The modem is also available at checkout. 802.15.4 Modem
Once a Reactor is configured, the Reactor monitors inputs. When inputs reach user-defined limits, relays can turn on or off. Reactors allow much more than simple relay control. Reactor inputs can trigger timers and rotations. A timer allows a relay to activate over a duration of time. A rotation is a simple counter, in which relays can be assigned to each "count". This allows powerful functions such as relay activation sequencing, flashing, and stepping. Event Piping allows timers and rotations to trigger other timers and rotations. This is very powerful for setting up complex relay activation sequences.
8 Inputs Available
Reactor Inputs play a vital role in the use of a Reactor controller. Analog inputs are simply inputs that are sensitive to voltages. Analog Inputs are capable of reading switches and sensors operating in the 0 to 5VDC range. Once configured, the Reactor CPU is constantly monitoring external sensors using 8 analog inputs that can read switches, resistance changes, or voltages from 0 to 5VDC. Inputs can be configured to trigger relays, relay timers and relay activation sequences.
Input Voltage Changes
Analog Inputs are very special in that they are sensitive to voltage changes. In the case of a Reactor controller, analog inputs have an 8-bit resolution, meaning the voltage input (from 0 to 5VDC) is interpreted as a value from 0 to 255.
- A voltage input of 0 Volts is interpreted as a value of 0
- A voltage input of 2.5 Volts is interpreted as a value of 128
- A voltage input of 5 Volts is interpreted as a value of 255
So if you divide 5 Volts by 256 possible steps (0-255 for 8-Bit resolution), the Reactor controller is sensitive to voltage changes as small as 0.0195 Volts. A Reactor controller has 8 inputs. Each input is capable of reading a separate voltage from 0 to 5 VDC, provided all voltages can share a common ground.
Who's Qualified to Use the Reactor Series?
Some computer skills required. The Reactor Relays do not require programming, simply configure the device with the included Base Station Software. While programming is not required and simple functions can be done rather easily with basic computer skills, complex events can be configured which will require some understanding and patience.
Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of USB devices, customers may experience loss of communications until the device is reconnected to the USB port. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video
SPDT Relay Controller
This device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed.
When the relay is off, the common is connected to the normally closed connection of the relay (see diagram to the right). When the relay coil is energized, the Common swings over to the Normally Open Connection of the Relay . You can wire the device you are switching to either the Normally Open or the Normally Closed position. With the 20-amp version wiring is done directly to the Relay terminals using a common 1/4" quick disconnect terminal. To the left is a picture of the connector that will connect to the relay (not included).

Base Station Software
Base Station will assist you in learning how this device functions and is the ultimate reference tool for configuring, testing and controlling this device. Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software. Base Station works by communicating with your controller to identify the model and provides the appropriate graphical user interface for setting up and testing the identified device. All Reactor configurations will be made through Base Station and an overview will be discussed below. To help you get started and learn this controller Quick Start Guides are available for just about every feature. As you discover a feature in Base Station a link is provided where you can easily download the Quick Start Guide.
Configure Each Input
The Reactor Relay allows users to define the activation of a relay or an event
based on the voltage readings of the analog inputs. An input can trigger a relay directly or an input can trigger an
event, such as a timer. If an input triggers a relay, the relay may turn on. If an input triggers a timer event, a timer may be started,
but a relay may or may not be turned on based on how you have configured the controller (the time delay may be before the relay triggers). Triggering an event does not mean you are triggering a relay, it just means you are triggering an internal function. Relays may be associated
with this internal function to achieve a large number of possible operations.
Using Input Values
Reading from Left to right, the settings above indicate Input 1 will trigger a relay when Analog Input 1 is above 200. We have defined that a relay will turn on when the input level is defined by a value of 200.
In the above example, a relay is triggered when an analog input is inside a set range between 100 and 202. By defining two limits, you can further narrow the parameters for the activation of a relay. The limits can also be assigned to set the relay to be activated outside two set limits.
Reactor controllers have up to 8 relays available depending on the actual model selected. Each relay can be assigned to a different input or event. In the example shown below, Relay 1 is Controlled by Input 1 directly. Input 1 will turn Relay 1 ON. In order for Relay 1 to activate, it must meet the conditions of the Input 1 configuration using the settings on the Input Configuration tab (see above).
There are many ways to directly control a relay from an input. Relays 1-5 in the below example shows how inputs can turn relays
on, off, toggle relay state, set the relay to match the state of the input, or set the relay to NOT equal the state of a input.
In the example below, Relay 6 is controlled by Timer 1. In other words, if Timer 1 is active, the relay will stay ON. Otherwise, the relay will turn off. This is a great way to activate a light for a given period of time. If you are interested in Time Delay Relay, timers will be discussed on our Time Delay Relay Page.
The configuration software makes it easy to configure each relay. Relays or multiple relays can be can be assigned to each input.
