PR Electronics 9202A Pulse Isolator is a high-performance device designed for the reliable transmission of signals from NAMUR sensors and mechanical switches. It offers advanced configuration and monitoring capabilities via a detachable display front (PR 45xx), making it suitable for a wide range of industrial applications, including safety-integrated systems.

Advanced Features

  • Configurable Display: Configuration and monitoring are facilitated by a detachable display front (PR 45xx).
  • Channel Function Selection: Allows selection of direct or inverted function for each channel via PR 45xx.
  • Advanced Monitoring: Monitors internal communication and stored data for enhanced reliability.
  • Redundant Supply: Optional redundant supply via power rail and/or separate supply ensures continuous operation.
  • SIL 2 Functionality: Optional SIL 2 functionality can be activated through a menu point, meeting IEC 61508 requirements.

Applications

  • Safe Area and Hazardous Zone Mounting: Can be mounted in safe areas and Zone 2 / Class 1, Division 2, Group A, B, C, D.
  • Pulse Isolation: Ideal for the transmission of signals from NAMUR sensors and mechanical switches.
  • Error and Cable Breakage Monitoring: Monitors error events and cable breakage via individual status relay and/or collective electronic signal via the power rail.
  • Safety Applications: Designed, developed, and certified for use in SIL 2 applications according to IEC 61508 requirements.
  • Performance Level Compliance: Suitable for use in systems up to Performance Level “d” according to ISO-13849.

Technical Characteristics

  • LED Indicators: One green and two yellow/red front LEDs indicate operation status and malfunctions.
  • High Galvanic Isolation: Provides 2.6 kVAC galvanic isolation between input, output, and supply, ensuring robust signal separation.

Mounting

  • Flexible Mounting: Can be mounted vertically or horizontally without distance between neighboring units, optimizing space utilization.

PR Electronics 9202A Pulse Isolator is an excellent solution for industries requiring reliable pulse signal isolation, advanced monitoring features, and compliance with stringent safety standards, particularly in environments with rigorous safety and performance demands.
