Output Modules

Reliable Controls® output modules provide simple, flexible, and economical output configurations for the MACH-Stat™ and MACH-Pro™ series controllers.

Switch Kit

The Switch Kit (CC-SK) provides convenient dual EIA-232 port access to any MACH1™ or MACH2™ controller, when used in conjunction with a standard A/B Box (sold separately).   The Switch Kit is ideal for installations that must have PC and modem connections made to one MACH1™ or MACH2™ controller.

Power Supply – VDC

The PS-VDC is a Variable Power supply board suited to powering such devices as pressure transducers, gas dectors, and humidity sensors, which require a DC power supply.   The PS-VDC can be field adjusted to give the desired output voltage by adjusting the trimmer/ potentiometer (P1). The board uses a half-wave rectifier such that the […]

TRIAC Module

The Reliable Controls® TRC-FP triac module allows control of a single floating point device from a single 0–10 VDC analog output. Load 1 and Load 2 cannot be energized simultaneously. The TRC-DS triac module allows control of 2 discrete digital devices from a single 0–10 VDC analog output. Load 1 is staged first and Load […]

Flow Sensor

Monitor flow in a Variable Air Volume (VAV) or constant volume air terminal precisely and easily with the Reliable Controls® Flow Sensor (FS).

Lighting Interface Module

The Reliable Controls® Lighting Interface Modules provide the ability to switch Panasonic WR61XX or GE RR series relays directly from Reliable Controls® MACH-System™ universal outputs.

SMART-Sensor eXpansion

The SSX allows the SMART-Net port to be expanded to 5 separate ports, greatly improving overall distance. The SSX also helps keep the wiring runs shorter which makes the SMART-Net network more robust and error free. An external power supply has been added for longer distances.   It is reccomended to use the SSX when […]

Current Switches

The A/ACS and A/ASCS are Solid State Current Switches with an adjustable trip point. The switches on these units are activated upon reaching a desired amperage setpoint. The Split Core design is ideal for retrofit applications and the mounting base is 35mm DIN Rail mountable. They include a Red and Green LED that indicate the […]
