The GMC 8364 controller is a gas measuring computer mounted in the assembly housing for installation in a control cabinet. Combined with up to 64 detectors with an output of 4-20 mA, the GMC 8364 displays the gas concentration and triggers safety responses if the gas concentration is too high. Up to 48 outputs can be connected to this flexible system with the aid of extension cards.

The GMC 8420 controller is a convenient wall-mounted control system that requires no additional internal wiring. The GMC 8420 can be used for direct alarm triggering with its internal signaler or to control external signalers. Up to 4 measuring points can be connected to the unit. All of our 4-20 mA sensors are suitable. Additional functionality is provided by the RK 8420, which features 4 programmable relay outputs for alarms 1 and 2 and buzzer. The GMC 8420 is designed to be connected to detectors in explosion zone 2.
