Time Activated Relay
Boards That Know What Time It Is
Time Activated Relay Controllers a have an integrated battery backed Real Time Clock with memory that allows users to control relays based on a time schedule. Use your computer to setup the time schedule and store into the controller. Once stored, the computer is not required, and will activate relays according to a schedule that can be as simple or as complex as your application requires.
Time Delay Relay
Configure Time Relay will Remain Active
Our Reactor Series controllers make a great time delay relay. You can define up to 8 timers that run in the background. Each timer can have a different time assigned to it. Timers can be triggered orcanceled based on input events. Relays can be associated with timers so the relays only come on when the timer is active. Timers support Event Piping. Event Piping means a timer can trigger another timer or another event
after the timer has completed its cycle.
Configurable Time Delay
Trigger with Sensor or Key Fob
Timer Software Available
Software for Easy Configuration Without Programming
Start your search for the right controller by the number of relays installed on each controller.
To break down further look for Shop By Channel on the left navigation and see the computer interfaces available for each channel option.
These boards are designed for specific applications. Reactor, Key Fob & don't require a computer during operation. MirC/X don't require a computer at all.
To break down further look for Shop By Application on the left navigation and see the channel options for each controller.
Start your search for the right controller by the interface of the controller or in other words how it will connect to your computer.
