PR Electronics Universal uni-/bipolar signal transmitter

PR-4184

Measures DC inputs up to ±300 V / ±100 mA with spans as low as 25 mV / 0.5 mA
Passive/active current output and buffered voltage output
Fast < 20 ms response time and excellent 0.05% accuracy
Universally powered by 21.6…253 VAC / 19.2…300 VDC

Application

  • 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.

Technical characteristics

  • The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.
  • Possibility of output safety readback by selecting S4...20 mA output.
  • The current output can drive up to 1000 Ohms, with an adjustable response time of 0.0…60.0 seconds.
  • Exceptional mA output load stability of < 0.001% of span / 100 Ohm.
  • Meets the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.
  • Meets the NAMUR NE43 recommendations, allowing the control system to easily detect a sensor error.
  • Tested to a high 2.3 kVAC, 3-port galvanic isolation level.

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.
  • Configuration, monitoring, 2-point process calibration and more are accomplished using PR's 4500 series of detachable displays.
