EURAX DME 424/442
Programmable Multi-Transducers
for the measurement of electrical variables in heavy-current power systems Application
The EURAX DME 4 series of multi-transducers (Fig. 1) simulta-neously measure several variables of an electric power system and process them to produce 2 resp. 4 analog output signals. 2 or 4 digital outputs are available for signalling limits or energy metering. For two of the limit outputs up to three measurands can be logically combined.
The multi-transducers are also equipped with an RS 232 serial interface to which a PC with the corresponding software can be connected for programming or accessing and executing useful ancillary functions.
The usual modes of connection, the types of measured variables, their ratings, the transfer characteristic for each output etc. are the main parameters that have to be programmed.
Ancillary functions include a power system check, provision for displaying the measured variably on a PC monitor, the simulation of the outputs for test purposes and a facility for printing name-plates.

Reference conditions
Limits of output signal for input overload The outputs A, B, C and D may be either short or open-circuited. They are electrically insulated from each other and from all other System response
All the full-scale output values can be reduced subsequently using the programming software, but a supplementary error results.
The hardware full-scale settings for the analog outputs may also be changed subsequently. Conversion of a current to a voltage output or vice versa is also possible. This necessitates changing resistors on the output board. The full-scale values of the current and voltage outputs are set by varying the effective value of two parallel resistors (better resolution). The values of the resistors are selected to achieve the minimum absolute error. Calibration with the programming software is always necessary following conver- sion of the outputs. refer to the Operating Instructions. Caution: The warranty is void if the device is tampered with!
