Fast & Reliable
Versatile and microprocessor-controlled, this powerful fixed system controller is simple to install and operate. Compatible with sensors directly for LEL level combustibles, oxygen, hydrogen sulfide, or carbon monoxide, this controller works with any 4 to 20 mA transmitter (two- or three-wire, 24 V DC).
Sensors can be mounted directly at the controller housing or can be wired remote from the controller. In addition, the 10 A rated relay contacts allow direct control of external alarms and horns and the digital display has backlighting and simultaneous readout of the gas type and concentration.
Moreover, this system controller is also housed in a NEMA 4X rated case for a weather tight seal that complies with lock out/tag out standards and can be fully secured. Silence the alarm from outside of the controller housing with the external reset switch.
