Universal input: One device for all your sensors
The key to true flexibility lies in universal input capability. Our multifunctional devices are designed to accept signals from virtually any sensor or process instrument, including RTD, Thermocouple (TC), Ohm, potentiometer, mA, and V inputs. This means a single device, such as the 4114 or 4116 Universal Transmitter, can be deployed in various applications without requiring different hardware. This level of universality simplifies system design, streamlines procurement, and ensures you always have the right device on hand for any signal conditioning task.
Flexible output options for seamless integration
To ensure seamless integration with your control systems, actuators, and alarms, our multifunctional devices provide a wide array of output options. Depending on the model, you can select from analog current (mA), voltage (V), relay outputs, and frequency signals. Devices like the 4116 Universal Transmitter offer exceptional versatility with current, voltage, and two relay outputs in a single unit. Whether you need to convert, split, amplify, or isolate a signal, our multifunctional range provides the flexibility to meet your exact requirements, ensuring your process signals are accurately and reliably transmitted to your control system.
Powered for any environment: Universal AC/DC supply
Designed for global use and simplified installation, most of our multifunctional devices feature a universal power supply that accepts both AC and DC sources. This is a standard feature across much of our popular 4000 series, including the 4104 and 4114 transmitters. The practical advantage is significant: it simplifies electrical design, eliminates the need for specific power supplies for different locations, and ensures that the same device can be deployed anywhere in the world without modification, saving both time and money.
Advanced functionality: Beyond simple conversion
Our multifunctional range extends beyond simple signal conversion to include devices with advanced capabilities for process protection and control. The 4131 Universal Trip Amplifier provides critical process protection with its reliable relay outputs for alarm generation. For applications requiring mathematical operations on signals, the 5115A Signal Calculator offers advanced functionality. Furthermore, our frequency converters, like the 4225, are designed to handle complex pulse and frequency signals with precision. For the most critical applications, the EMPHASIS assessed 9116A-EMP offers a SIL 2-certified solution for the nuclear industry, demonstrating the range's suitability for even the most demanding environments.

What makes a PR electronics "multifunctional" device different from a dedicated temperature transmitter or isolator?
A multifunctional device such as the PR 4116 accepts virtually any standard process input — RTD, thermocouple, linear resistance, potentiometer, milliamp, and voltage — and provides multiple output types (current, voltage, and relay) in a single housing. This eliminates the need to stock different device variants for different signal types. One PR 4116 can be repurposed from a temperature measurement application to a pressure transmitter signal conditioning application simply by reconfiguring its parameters, reducing inventory and simplifying maintenance.
What input and output combinations does the PR 4116 Universal Transmitter support?
The PR 4116 accepts RTD (Pt, Ni, Cu families), thermocouples (B, E, J, K, L, N, R, S, T, U, W3, W5, LR), linear resistance (0-10,000 Ω), potentiometer (10 Ω-100 kΩ), current (0-23 mA), and voltage (0-12 VDC). Outputs include programmable current (0-20/4-20 mA, max load 800 Ω), voltage (0-10 VDC), and two potential-free relay contacts rated at 250 VAC/VDC, 2 A, 500 VA. The relay functions include setpoint, window, sensor error, latch, power, and off modes.
What is the signal calculator PR 5115A, and what applications does it serve?
The PR 5115A accepts inputs from RTD, Ohm, thermocouple, millivolt, milliamp, and voltage sources and can duplicate the input signal to multiple outputs or perform mathematical functions on the signal before outputting it. Typical applications include splitting a single sensor signal to feed two independent control loops, providing a local display output alongside a remote control system output, or converting between signal standards (e.g., TC input to 4-20 mA output) with universal AC/DC power supply flexibility.
What power supply options are available for PR electronics multifunctional devices?
Most PR 4000-series multifunctional devices feature a universal power supply accepting both AC (21.6-253 VAC, 50/60 Hz) and DC (19.2-300 VDC) input. This means a single device can operate on any available supply voltage worldwide — from 24 VDC instrument power to 230 VAC mains — without hardware changes or separate models. The PR 5000 series typically operates on 2-wire loop power (>16.5 V) or universal AC/DC supply depending on the model. Power consumption ranges from 2.5 W to 3.5 W.
What accuracy and response time can be expected from PR electronics multifunctional devices?
The PR 4116 achieves accuracy better than 0.1% of the selected range, with an EMC immunity influence of less than ±0.5% of span. Extended EMC testing per NAMUR NE21 criterion A shows less than ±1% of span influence. Response time for temperature inputs is ≤1 second (0-90%), while mA/V inputs respond in ≤400 ms. The signal-to-noise ratio exceeds 60 dB across the 0-100 kHz band. These specifications are consistent across the 4000 series, making multifunctional devices suitable for demanding process control loops.
