Sensor Relay Control
The board can be configured to trigger a relay from a sensor attached to the analog inputs on the board. 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, delays and relay activation sequences.
Selecting The USB Interface
By selecting the USB interface you will be configuring through the USB port of your computer and uploading these settings to the board. Boards on this page are equipped with a ZUSB communications module that adds USB communications to the board. At any time, a computer may monitor the Reactor, Trigger Events, Activate Relays, or Change Configuration settings.
Selecting a USB Relay Board
Below you will find the 8-Channel USB Relay control that are available. The difference being the amperage of the relays installed and the type of relay. Choose the controller that fits the amperage you are switching. You will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version in 30 amp. For more information on selecting the correct relay for your application see Choosing a Proper Amperage
