The PR 3108 Isolator Repeater / Splitter is a high-performance DIN-rail mounted signal conditioning solution designed to isolate, repeat, and distribute standard DC analog signals for industrial automation, process control, and instrumentation systems. It provides galvanic separation of current signals, thus eliminating ground loops and protecting control systems such as SCADA and PLC equipment from surges, noise, and transient interference. With a splitter function that converts one input into two isolated outputs, the 3108, from PR electronics, is ideal for feeding the same signal to multiple measurement or control channels without electrical interference.
- Galvanic separation of analog current signals.
- A competitive choice in terms of both price and technology for galvanic isolation of all signal types to SCADA systems or PLC equipment.
- High 4-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
- All terminals are over-voltage protected, polarity protected and short-circuit protected.
- The device can be mounted in Safe area or in Zone 2 / Division 2 hazardous areas and features approval for marine applications.
PR 3018 Isolator Repeater and Splitter from PR electronics
Providing simplicity and reliability, the PR 3018 requires no configuration and features a fast response time of less than 7 ms along with excellent signal-to-noise performance (>60 dB). Its slim 6.1 mm housing allows up to 163 units per meter on standard DIN rail, optimizing space in crowded control cabinets.
- Flexible 24 VDC (±30%) supply via power rail or connectors.
- Factory-calibrated measurement ranges. Fast response time < 7 ms.
- Excellent signal/noise ratio > 60 dB. High galvanic isolation of 2.5 kVAC.
- Inputs and outputs are floating and galvanically separated.
- A green front LED indicates normal operation and malfunction.
- Wide ambient temperature range: -13 to 158˚F (-25 to 70˚C).
Easy Mounting, Installation, and Programming
The PR 3108 supports flexible 24 VDC (±30%) power via power rail or terminal connections and includes comprehensive protection at all signal terminals against over-voltage, reverse polarity, and short circuits. High-level isolator repeater and splitter for up to 2.5 kVAC and broad environmental tolerance -13 to 158˚F (-25 to 70˚C) ensure robust performance in challenging industrial and marine environments.
- TThe narrow 6.1 mm housing allows up to 163 units per meter.
- Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 158˚F (70˚C) ambient temperature.
- Units can be supplied separately or installed on PR 9400 power rail.
