Configure Once. Operate Automatically.

Upload your configuration one time, disconnect the computer, and let the Reactor Controller do the work. It continuously monitors sensors, makes decisions, and controls relays automatically without requiring a connected PC.

Looking for reliable sensor relay control? Reactor Controllers automatically turn sensor inputs into relay outputs.

Sensors Trigger Intelligent Relay Control

The Reactor Series is more than a relay controller. It continuously monitors up to 8 analog or contact closure inputs and makes decisions based on the conditions you define. Once configured, the Reactor operates completely on its own, automatically activating relays, starting timers, and responding to sensor changes without requiring a connected computer.

Whether you're monitoring a temperature sensor, float switch, pressure sensor, push button, or dry contact output, the Reactor responds instantly using the logic you've configured in the included Base Station Software.

Powerful Automation Without Programming

Create automation using simple point-and-click configuration instead of writing software. Configure relays to activate above or below a sensor threshold, remain energized within a specific operating range, or trigger after an adjustable time delay.

Need something more advanced? Configure up to 8 independent timers and 4 rotation counters to sequence relays, create timed operations, or build complex automation routines. Once your configuration is uploaded, the Reactor continues operating autonomously with no computer required.

Choose the Right Reactor Relay

Reactor Relay Controllers are available with 1, 2, 4, or 8 onboard relays, each featuring 8 analog/contact closure inputs for connecting sensors, switches, and other control devices.
