PR Electronics Universal uni-/bipolar voltage and current signal transmitter


Measures and outputs uni-/bipolar voltage and current signals
Works with both passive and active inputs and outputs
Uses the PR 4500 display series for programming and process monitoring
Fast < 20 ms response time and excellent < 0.05% accuracy
Universally powered by 21.6…253 VAC / 19.2…300 VDC

Fast < 20 ms response time for measuring signals produced by torque, position, current & acceleration sensors.
User configurable bipolar or unipolar I/O means the 4104 is suitable for nearly any voltage or current conversion.
The excitation source enables measurement of two or three wire transmitters.
The active or passive I/O makes the 4104 perfect for power matching current loops.
Converts narrow bipolar inputs to wide bipolar or unipolar outputs, e.g., ±1 volt input = ±10 volt or 4...20 mA output.
Selectable direct or inverse I/O makes the 4104 suitable for proportional control applications.
The ”V-curve” function outputs 100% – 0 – 100% when a 0 – 100% input signal is present.

Technical characteristics
The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.
The current output can drive up to 800 Ohms, with an adjustable response time of 0.0…60.0 seconds.
Exceptional mA output load stability of 60 dB.

Mounting / installation / programming
Very low power consumption means units can be mounted side by side without an air gap – even at 60°C ambient temperature.
Approved for marine applications.
Configuration, monitoring, 2-point process calibration and more are accomplished using PR's 4500 series of detachable displays.
All programming can be password protected.
