    The switching module is a device for expanding the capabilities of the system.

    MK-140 is the best option for connecting 9-11 sensors.

    In MK-140 intrinsically safe barriers for connection of the electric equipment (sensors, indicators) located in an explosive zone are established.

     

    Capabilities:

    • Intrinsically safe power supply of sensors located in the hazardous area;
    • Connection of additional devices (sensors, indicators, converters, actuators);
    • Serial connection of switching modules.
