RISH Ducer M40 is a programmable transducer with a RS 485 bus interface (MODBUS®).It supervises several variables of an electrical power system simultaneously and generates 4 proportional analogue output signals.

The RS 485 interface enables the user to determine the number of variables to be supervised (up to the maximum available). The levels of all internal counters that have been configured (max. 4) can also viewed. Provision is made for programming the RISH Ducer M40 via the bus. A standard EIA 485 interface can be used,but there is no dummy load resistor for the bus.
