ANALOGUE RETRANSMISSION (ON REQUEST)

From 0 to 20 mADC / from 0 to 10 VDC, programmable within the whole

range of retransmission;

Accuracy and response time: ± 0.3% F.S. (@ 25°C) / 500 ms (filter

excluded);

Temperature drift: ± 200 ppm/°C

Load: output 0 to 20mA: ≤ 500 Ω, output 0 to 10V: ≥ 10 kΩ

Insulation: by means of optocouplers, 500VRMS between output and

measuring inputs, 2000VRMS between output and power-supply input.

SERIAL RETRANSMISSION (ON REQUEST)

RS485; multidrop: one-way (STD); bidirectional (on request); 2 or 4

wires; max. distance 1200m; termination and/or line bias directly on the

instrument; 255 programmable addresses; data format: 1 start bit, 8 data

bit, no parity, 1 stop bit; baud rate: 1200, 2400, 4800 and 9600 baud

selectable by key-pad; protocol according to the standard MODBUS;

One-way communication:

dynamic data (reading only): measurement, valley data, peak data,

alarm status;

Static data (reading/writing): all programming data.

Bidirectional communication:

dynamic data (reading only): measurement, valley data, peak data,

alarm status;

Static data (reading/writing): all programming data, reset of peak and

valley data, reset of alarm set-points with latch.

Insulation: by means of optocouplers, 500VRMS between output and

measuring inputs, 2000VRMS between output and power supply inputs
