PR 4104 Universal Unipolar / Bipolar Signal Transmitter

The PR 4104 Universal Unipolar / Bipolar Signal Transmitter is a high-performance signal conditioning and conversion device for industrial automation, control systems, and process measurement applications. This versatile universal transmitter accepts both unipolar and bipolar voltage (±12 V) and current (±23 mA) signals, active or passive, as well as converts them into configurable outputs. Thus, the 4104, from PR electronics, makes for easy integration with PLCs, DCS, and SCADA systems. Its universal power supply ranges from 21.6-253 VAC or 19.2-300 VDC, thus making it suitable for a wide variety of global installations.

• Fast < 20 ms response time for measuring signals from torque, position, current, as well as acceleration sensors.
• User configurable bipolar or unipolar I/O means the PR 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, for example, ±1 volt input = ±10 volt or 4-20 mA output.
• Selectable direct or inverse I/O makes the PR 4104 suitable for proportional control applications. 
• The "V-curve" function outputs 100% – 0 – 100% when a 0 – 100% input signal is present.
