PR 3105 Isolation Converter

The PR 3105 Isolated Converter is a high-performance DC signal isolation and converter module for industrial automation, SCADA systems, and PLC interfaces. Ideal for ensuring robust signal integrity in complex control environments, this converter, from PR electronics, provides galvanic isolation of standard analog current and voltage inputs, thus effectively eliminating ground loops and protecting downstream control systems from noise, transients, and interference.

• 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 are over-voltage protected, polarity protected and short-circuit protected.
• Approved for marine applications.

PR 3105 Isolation Converter from PR electronics

Encased in an ultra-slim 6.1 mm DIN-rail housing, the PR 3105 allows up to 163 units per meter, enabling high-density installation in compact control cabinets. Its flexible 24 VDC (±30%) power supply can be fed through either power rail or terminal connectors, while factory-calibrated measurement ranges and DIP-switch configuration simplify setup and reduce commissioning time. The unit’s fast response time of <7 ms and excellent signal-to-noise ratio (>60 dB) deliver accurate, real-time signal transmission for demanding process applications.
