DESCRIPTION
DECODE EMU devices represent series of measuring devices for measurement of AC and DC voltages and currents with integrated RS-485 Modbus connection.
There are three different device options supported where the third one, with analogue input unit, offer several subtypes.
- EMU V3 – for AC voltages measurement 3 x 230V AC
- EMU C3 – for AC currents measurement (current transformers) 3 x CT 5A AC
- EMU A3-TTT – 3 x analogue input measurement (TTT designates input type, example: device EMU A3001 features first two inputs 0/4-20mA where the third one features PT100 input)
WIRING DIAGRAM
Jumpers KS1 and KS2 are to be placed only if RS-485 line termination is required. For short distances the termination is not needed. Distances longer than 100m, as well as presence of notable disturbances, require line termination at one of slave devices, specifically the one positioned at the end of line.
