Applications

• Fast <20ms 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., ±1vDC input = ±10vDC or 4-20mA 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.

Features

• Measures and outputs uni-/bipolar voltage and current signals.
• Works with both passive and active inputs and outputs
• Fast <20ms response time and excellent <0.05% accuracy
• Universal powered AC or DC power supplies
• Programmable by way of detachable display front (4501)

PR 4501 Display / programming front

Application:

• Communications interface for modification of operational parameters in 4104.
• Can be moved from one 4104 module to another and download the configuration of the first transmitter to subsequent transmitters.
• Fixed display for readout of process data and status

Technical characteristics:

• LCD display with 4 lines: Line 1 (H = 5.57 mm) shows the scaled process value; Line 2 (H = 3.33 mm) shows the selected engineering units; Line 3 (H = 3.33 mm) shows analogue output or TAG no; Line 4 shows status for communication and signal trending.
• Programming access can be blocked by assigning a password. The password is saved in the converter in order to ensure a high degree of protection against unauthorised modifications to the configuration.
