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.
