PR Electronics 4100 Series Universal Transmitter, Universal Input, Relay Output, Supply Voltage 21.6 V ac to 300 V ac 4131

PR Electronics 4131 Universal Transmitter is a multifunctional signal conditioner designed for industrial signal conditioning with a universal input and relay output. It operates with a supply voltage range from 19.2 V dc through 21.6 V ac up to 300 V ac, making it suitable for a wide range of industrial environments.

The transmitter supports numerous inputs such as RTD and thermocouple for temperature measurement, linear resistance, potentiometer, voltage, and current including 2-wire transmitter signals. It is equipped with dual pairs of potential-free relay contacts configurable for latching or alarm functions, defined by adjustable high and low setpoints via its window function.

This device features 2.3kV ac galvanic isolation ensuring robust separation between input and output lines and enhancing signal integrity under noisy industrial conditions. Its operating temperature spans from - 20°C to 60°C, allowing use in diverse environments. The sturdy design includes DIN rail mounting compatibility and IP20 protection with screw terminal connections.

Compliance with multiple international standards including RoHS, DNV GL, EAC, UKCA, UL, and CE certifies this transmitter's reliability and safety for demanding applications. It comes with clear LED indicators: a green LED signaling normal operation and fault detection, and yellow LEDs that show relay output status for easy diagnostics.

Programming the 4131 universal transmitter is simplified through the optional PR 4510 detachable display module which offers easy navigation of input/output parameters, calibration, diagnostics, and password protection to secure configuration settings. This makes it ideal for industrial automation, process control, laboratory instrumentation, and signal conditioning tasks requiring accurate relay switching and signal processing.
