MK – 140 GAZ commutation module is a stand-alone device that meets oil and gas safety regulations. It’s operated with gas analyzer sensors. There are intrinsic safety barriers (a repeater RS-485), ex-marking II 3G Ex nA [ia Ga] [ib Gb] IIB T4 Gc in MK-140.
Capabilities:
- Intrinsically safe power supply sensors, digital transducers and other devices installed in ex-areas;
- Status monitoring of connected devices;
- Indication of current measurement channel readings on standard visual displays;
- Settings threshold limit value for measurement channels;
- Audible alarm activation when the thresholds are exceeded;
- Quick audible alarm deactivation;
- Warning lights activation when the thresholds are exceeded;
- External actuator verification mode;
- External safety actuator control;
- Sending data to a DEL-150 control module for subsequent recording;
- Indicating connection status to the DEL-150 control module.
Design Features:
- Accessible connection with other devices if there are free outputs RS-485.
