Bipolar current / voltage input
Signal conversion
Current and voltage output
24 VDC supply or universally supplied
Applicable in PELV/SELV circuits


Programmable input and output ranges using internal DIP-switches.
Front panel fine adjustment of 0 and 100% values for special ranges.

Galvanic separation of analog signals.
Measurement of floating signals.


Analog signal conditioning with microprocessor based gain and zero offset with a fast response time of less than 25 ms.

Signal conversion within the ranges: -250...+250 VDC or -50...+50 mA on the input and 0...10 (20) VDC and 0...20 mA on the output.

Galvanically separated between input, supply, and output.

2-wire transmitter supply and a reference voltage of 2.5 VDC, max. 15 mA for short circuit-protected supply of potentiometers.

Buffered voltage output 0...20 V, 10 mA.

The output can be ordered for standard 0/4...20 mA, and 0/1...5mA or special currents and selectable voltages within the signal range 0...1 VDC or and ranges 0...10 VDC.

Output signal reversal.

Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
