PR 3104 Isolated Converter

The PR 3104 Isolated Converter is a precision signal isolator and converter for enhancing the reliability and integrity of standard DC process signals in demanding industrial environments. It provides galvanic isolation and conversion of analog current and voltage signals, eliminating ground loops and protecting sensitive control systems from noise, transients, and common-mode interference. With a slim 6.1 mm DIN-rail housing, the 3104, from PR electronics, maximizes panel density and allows up to 163 units per meter, optimizing cabinet space without sacrificing performance.

• Galvanic separation of analog current and voltage 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 offer protection from over-voltage, polarity, and short-circuit.
• The device can mount in Safe area or in Zone 2 / Division 2 hazardous areas and is features approval for marine applications.

Designed for seamless integration, the 3104 offers factory-calibrated measurement ranges and simple DIP-switch configuration, making setup quick and intuitive. Its high 3-port isolation of up to 2.5 kVAC and excellent signal-to-noise ratio (> 60 dB) ensure clean, stable signals for PLCs, SCADA systems, and automation equipment. A fast response time (< 7 ms) and robust protection from over-voltage, polarity, and short-circuit safeguarded terminals further enhance reliability.

• 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 converter supports loop power supply (> 17 V) for 2-wire transmitters and operates across a wide ambient temperature range -13 to 158˚F (-25 to 70˚C), making it suitable for industrial, marine, and hazardous area installations (Zone 2/Division 2). A front green LED clearly indicates normal operation and fault status, ensuring easy diagnostics and peace of mind.

• Easy configuration via DIP switches.
• 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.
