Application

Power supply and switching units are designed to provide power supply to devices and control actuators by switching relay contacts using signals of “SENS” Measurement System devices.  Power supply and switching units with “-GS” index are also equipped with output for siren VS-3-12V. Each relay and siren output can be programmed for triggering using single  or multiple values of measured parameters of single or multiple sensor allowing to set required algorithm for automatic control, interlocks and signaling. Switching units are programmed using MS-K-500-... signaling device or PC with “Configuration” software (LIN-RS232... or  LIN-USB adapter is required).

Design

Power supply and switching units have different number of relays, power supply voltage and housing modification. Power supply and switching units in plastic housing have explosion-proof modification in metal housing with “VZ” index (fig. 1 ... 3). List and technical specifications of power supply units units are shown in table 1, connection diagrams are shown in fig. 4 ... 7.
