Universal uni-/bipolar signal transmitter

4104

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.

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 < 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.
Approved for marine applications.
Programming, monitoring, and 2-point process calibration is accomplished with the 4501 detachable display.
All programming can be password protected.
