  • Fast < 20 ms response time for measuring signals produced by torque, position, current & acceleration sensors.
  • User configurable bipolar or unipolar I/O means the 4184 is suitable for nearly any DC voltage or current conversion.
  • Freely programmable between ±300 VDC and ±100 mA.
  • The excitation source allows measurement of a 2-wire or 3-wire transmitter, or a potentiometer.
  • Converts narrow bipolar inputs to wide bipolar or unipolar outputs, e.g., ±1 volt input = ±10 volt or 4...20 mA output.
  • Configurable input limits control the output value for increased safety.
  • ±20 VDC buffered voltage output for controlling devices like the PVG 32 valve (6...18 VDC).
  • Designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.
  • Suitable for the use in systems up to Performance Level “d” according to ISO-13849.
