  • Overview

  • Technical details

  •  

    Advanced features

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

    Application

    • Galvanic separation of analog signals.
    • Measurement of floating signals.

    Technical characteristics

    • 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.
