Universal uni-/bipolar signal transmitter

4184

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).
The 4184 has been designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.

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.

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 45xx detachable displays.
All programming can be password-protected.
