PR 3103 Isolated Repeater

The PR 3103 Isolated Repeater delivers dependable galvanic isolation and 1:1 signal transfer for standard analog current loops, safeguarding your control system from noise, transients, and ground loops. Ideal for industrial environments, the PR 3103 provides high 3-port isolation with superior surge suppression and a clean signal path that protects PLCs and SCADA systems. The 3103, from PR electronics, offers fast response time of under 7 ms and excellent signal-to-noise ratio (> 60 dB) ensure accurate, real-time signal integrity even in electrically harsh conditions.

• 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 3-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
• All terminals provide protection from over-voltage, polarity, and short-circuit.
• The device can mount in Safe area or in Zone 2 / Division 2 hazardous areas and features approval for marine applications.

The slim 6.1 mm DIN-rail housing maximizes cabinet and panel space, allowing up to 163 units per meter while simplifying installation side-by-side without air gaps. Input and output circuits are floating and galvanically separated, and all terminals offer protection against over-voltage, reverse polarity, and short circuits for extra reliability. A green front LED on the PR3103 isolated repeater provides clear operational status at a glance.

• 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

Flexible 24 VDC power via rail or connectors, reinforced 2.5 kVAC isolation, and a broad operating temperature range -13 to 158˚F (-25 to 70˚C) make the PR 3103 isolated repeater suitable for demanding automation, process control, and marine applications. It can be install in safe areas as well as Zone 2 / Division 2.

• The narrow 6.1 mm housing allows up to 163 units per meter.
• Units can mount 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.
