PR 5104A Repeater / Power Supply
Upgrade your instrumentation setup with the PR 5104A Repeater / Power Supply — a versatile, dual‑role device that powers two‑wire transmitters and isolates signals to protect your system. It offers universal supply (AC or DC), selectable measurement ranges via DIP switches, and high isolation (3.75 kVAC) between input, output, and supply. With response time under 25 ms and floating, galvanically separated input and output, it ensures accuracy, safety, and flexibility. Ideal for process control panels, retrofit projects, or any application requiring signal conditioning and power without sacrificing reliability. Simplify wiring, enhance safety, and maintain performance in a compact DIN‑rail package.
- Loop supply > 17.1 V supports transmitter power without external add-ons
- 20 factory‑calibrated ranges set via DIP‑switches for fast configuration
- 3.75 kVAC galvanic isolation guards against interference and ground‑loop issues

Description
The PR 5104A Repeater / Power Supply combines reliable signal isolation with a robust power supply for two‑wire transmitters. It comes in 1‑ or 2‑channel versions and provides 3.75 kVAC galvanic isolation between input, output, and also supply for maximum safety. The 5104A, from PR electronics, delivers loop supply greater than 17.1 V. In addition, it can be receive power via universal AC or DC (21.6‑253 VAC or 19.2‑300 VDC). This Repeater and Power Supply module includes 20 factory‑calibrated measurement ranges, selectable via internal DIP switches—no recalibration necessary in most cases.
- 1-channel or 2-channel version
- 3-port / 5-port 3.75 kVAC galvanic isolation
- Loop supply > 17.1 V; universal supply by AC or DC
- 20 programmable measurement ranges
PR 5104A Repeater and Power Supply
The PR 5104A supports analog current as well as voltage signals. Users can configure the output as an active transmitter, passive 2‑wire transmitter, in addition to voltage/current output. The response time is under 25 ms (0‑90%), thus ensuring responsive performance in control loops. Inputs, outputs, and supply are floating and fully isolated, preventing ground loops or interference. It mounts vertically or horizontally on a standard 35 mm DIN rail; the 2‑channel version allows up to 84 channels per meter when it mounts side‑by‑side.
- Power supply and signal isolator for 2-wire transmitters.
- Signal isolator for analog current as well as voltage signals.
- 1:1 or signal conversion of analog current / voltage signals.
Technical Characteristics
- The 20 factory-calibrated measurement ranges in the 5104A can be selected by the internal DIP-switches without the need for recalibration. Special measurement ranges can also be delivered.
- PR5104A relies upon microprocessor technology for gain as well as offset. The analog signal transmits at a response time of less than 25 ms.
- Inputs, outputs, and supply are floating in addition to being galvanically separated.
- The output can connect either as an active current / voltage transmitter or as a 2-wire transmitter.
Applications
- Powering and isolating 2‑wire transmitters in hazardous or industrial areas.
- Converting analog current or voltage signals for PLCs, DCS, or monitoring systems.
- Signal duplication or splitting with minimal interference over long cable runs.
- Use in chemical plants, oil & gas, water treatment, marine applications, or any platform needing precise analog isolation and power.
