PR UNIVERSAL TRANSMITTER 4114

PR UNIVERSAL TRANSMITTER 4114 – Programmable Signal Isolator and Converter

The PR UNIVERSAL TRANSMITTER 4114 (manufactured by PR Electronics, model 4114) is a high-performance, DIN-rail mounted universal signal conditioner and transmitter. Designed for industrial automation, process control, and safety-critical environments, the PR UNIVERSAL TRANSMITTER 4114 accepts a wide variety of input signals—including RTD, thermocouple, linear resistance, potentiometer, voltage, and current—and converts them into standard, linearized analogue current or voltage outputs.

As illustrated in the product image, the unit features a sleek 23.5 mm DIN-rail mount housing in PR Electronics’ signature red and dark grey enclosure. It includes a front green/red diagnostic status LED, screw-terminal connections, and a front slot interface that accommodates detachable programming/display fronts (such as the PR 4501, 4510, or 4511 Modbus display fronts) for tool-free configuration without DIP switches.

Key Features of the PR UNIVERSAL TRANSMITTER 4114

Universal Input Flexibility: Directly accepts RTDs (Pt100, Ni100, etc.), thermocouples (Type J, K, T, E, R, S, B, etc.), linear resistance up to $10text{ k}Omega$ , potentiometers, $text{mA}$ currents, and $text{V DC}$ inputs.
3-Port 2.3 kVAC Galvanic Isolation: Provides robust $2.3text{ kVAC}$ galvanic separation between input, output, and power supply circuits to eliminate ground loops and protect downstream PLCs.
Universal Supply Voltage: Powered by a flexible universal power supply accepting $21.6text{ to }253text{ V AC}$ ( $50/60text{ Hz}$ ) or $19.2text{ to }300text{ V DC}$ .
SIL 2 / Functional Safety Rated: Engineered according to strict safety standards, making it suitable for deployment in SIL 2 applications and Performance Level “d” installations.
2-Wire Transmitter Power Supply: Integrated loop supply ( $>16text{ V DC}$ ) directly energizes external 2-wire field transmitters.
Detachable Programming Modules: Configurable via plug-in communication fronts (PR 4501/4510/4511/4512) for process calibration, custom signal scaling, password protection, and Modbus RTU communication.

Common Applications and Industrial Usage

The input versatility, safety ratings, and high noise immunity of the PR UNIVERSAL TRANSMITTER 4114 make it a preferred choice across various process industries:

Temperature Measurement & Linearization: Linearizes electronic temperature readings from RTD or thermocouple sensors for accurate control in chemical, pharmaceutical, and oil/gas plants.
Valve Position & Linear Movement Tracking: Converts linear resistance variations from potentiometers, solenoids, or butterfly valves into standard $4text{--}20text{ mA}$ signals.
Signal Isolation & Noise Reduction: Eliminates ground loop interference and converts floating or non-standard analogue signals into clean $0text{--}10text{ V}$ or $4text{--}20text{ mA}$ PLC/DCS inputs.
Power & Signal Loop Isolation: Functions as an isolated power supply and signal conditioner for remote 2-wire field transmitters.

Operating Guidelines and Best Practices

SAFETY NOTICE: Ensure main supply power is switched off prior to wiring terminal connections.

No Hardware DIP Switches: All configuration settings are performed digitally via a plug-in PR 4500 series display/programming front.

LED Status Monitoring: A steady green front LED indicates normal system operation, while a flashing red LED alerts operators to sensor errors or internal device faults.

Wiring Torque: Secure conductor wires (up to $2.5text{ mm}^2$ ) into the screw terminals with a recommended tightening torque of $0.5text{ Nm}$ .

To review official international functional safety standards and IEC specifications for safety-rated signal conditioners, consult the official IEC 61508 Functional Safety Standardization Directory.
