4184 Universal Uni-/Bipolar Signal Transmitter

Universal uni-/bipolar signal transmitter

  • Measures uni-/bipolar DC current and voltage signals
  • Passive/active current output and buffered voltage output
  • Extremely good signal dynamics for spans from 25 mV to 300 VDC
  • Programming, process monitoring and diagnostics via 4511 / 4501
  • Fast < 20 ms response time and excellent 0.05% accuracy
  • Universally powered by 21.6…253 VAC / 19.2…300 VDC



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.
  • Each unit is tested to a high 2.3 kVAC, 3-port galvanic isolation level.
  • Excellent signal to noise ratio 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.
  • Configuration, monitoring, 2-point process calibration and more are accomplished using either the 4501 detachable display or the 4511 detachable digital communication enabler.
  • All programming can be password-protected.
