MFT Programmable Multifunction Transducer RISH Ducer M40 M30 M42, Voltage and Current Accuracy - 02 FS, Frequency Accuracy -002Hz, W Var WH VarH PF Accuracy - 05 FS

For the measurement of electrical variables in heavy current power system rish ducer m40 fig. 1 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 customer to determine the total count of variables to be supervised reaching as far as the maximum available . The levels of all internal counters which are configured max. 4 can also viewed. Provision is made for programming the rish ducer m40 via the bus. A standard eia 485 interface can but not, Serve as a single one dummy load resistor for the bus. The transducers are also loaded with an rs 232 serial interface to which a pc with the corresponding software is capable of linking for programming or accessing and executing useful ancillary functions. This interface is needed for bus operation to configure the the baud, Device address rate and possibly increasing the telegram waiting time if the master is too slow defined in the modbus protocol. The usual methods the types, Of connection of the transfer, Measured variables characteristic for, Their ratings each output and the kind of internal energy metering are the main parameters that is able to be programmed. The ancillary functions include a power provision for, System check displaying the measured variably on a pc monitor, The simulation of the outputs for test purposes and a facility for printing nameplates. The transducer fulfils all the essential requirements and regulations concerning electromagnetic compatibility emc and safety iec 1010 resp. En 61 010 . It was developed and is manufactured and tested in strict accordance with the quality assurance standard iso 9001.
