Input devices typically rely on sensor technology that measures temperature, pressure, humidity, light and electrical current. Output devices often use relay and actuator technology that controls motors, lights, air dampers and water valves.

The SMART-Net™ Relay is a compact, multichannel line-voltage relay solution that will save you time and money on installation.
The SMART-Net™ Relay 20A is a compact, multichannel line-voltage relay solution that will save you time and money on installation.
Aesthetically designed to complement any decor, the Reliable Controls SPACE‑Sensor™ Temperature provides a traditional temperature sensor solution with a wide range of options to help you achieve comfort.
The Reliable Controls® Lighting Interface Modules provide the ability to switch Panasonic/Douglas WR6161 or GE RR7 series relays directly from Reliable Controls MACH-System universal outputs. Each module supports two inputs and two outputs.
Monitor flow in a Variable Air Volume (VAV) or constant volume air terminal precisely and easily with the Reliable Controls® Flow Sensor (FS).
Double-up on the output capacity of your universal outputs using the Reliable Controls TRIAC modules. These low cost and convenient to install modules convert a single universal output into two TRIAC outputs.
Engineered to be one of the most reliable relays on the market, the Double-Pole Heavy-Duty Latching Relay is suitable for all types of loads, including capacitor-corrected HID ballasts. A manual-operation lever and indicator are built in for convenient operation and status check at the panel.
Engineered to be one of the most reliable relays on the market, the Single-Pole Heavy-Duty Latching Relay is suitable for all types of loads, including capacitor-corrected HID ballasts. The relay has a set of built-in auxiliary contacts that allow the connected controller to determine the position of the load contacts. A manual operation lever and indicator are also built in for convenient operation and status check at the panel.
Reliable Controls offers an entire range of mechanical relays that have been tested and approved for use with our controller outputs.
