GMC 8420
The GMC 8420 controller is a convenient evaluation system for wall mounting, which can be operated without further internal wiring.
The GMC 8420 can be used directly for alarming due to its internal signal generator, or it can control external signal generators.
Up to four measuring points can be connected. All our 4 – 20 mA sensors are suitable for this. The GMC 8420 was developed for further functionality. It has four freely programmable relay outputs for alarm 1, 2 and horn.
The GMC 8420 was developed for the connection of measuring probes in EX zone 2.
