PR Electronics 9200 Series Pulse Isolator, Switch Input, Relay Output, 19.2V dc and 31.2V dc Supply, ATEX 9202B2A

PR Electronics 9202B2A Pulse Isolator is a sophisticated single channel isolation barrier module tailored for industrial electrical signal conditioning and safety applications. This device is adept at receiving switch input signals and converting them into relay outputs with high integrity and galvanic isolation. It operates within supply voltages of 19.2V dc and 31.2V dc and carries an ATEX hazardous area certification, enabling safe use in explosive atmospheres.

The isolator employs transformer and optical isolation techniques to achieve 2.6 kV galvanic isolation between input, output, and power terminals, effectively protecting connected equipment and personnel from electrical interference or faults. It is designed to be mounted on DIN rails and features screw-type terminals for secure wiring.

The unit supports SIL 2 certification as per IEC 61508 ensuring compliance with functional safety standards in critical industrial installations. It incorporates extended self-diagnostics and cable fault detection, with visual front LED indicators to signal operational status and malfunctions.

The PR Electronics 9202B2A can accept signals from NAMUR sensors and mechanical switches located in hazardous zones including zone 0, 1, 2 and zone 20, 21, 22. Its intrinsic safety design limits energy at sensor contacts to prevent ignition of flammable atmospheres, even if wiring is compromised.

Configuration and monitoring are facilitated by a detachable display module (PR 4510), providing features like two-point calibration, process simulation, and comprehensive diagnostics through an intuitive user interface.

Supports switch input and relay output signals for safe and reliable signal conditioning. Galvanic isolation of 2.6 kV provides robust electrical separation. Certified for SIL 2 safety integrity level applications. Extended self-diagnostics and cable fault detection enhance reliability.

DIN rail mountable with screw terminal connections for easy installation. Operates over a temperature range from -20°C to 60°C. Front LED indicators for status and alarm conditions. Configurable with detachable PR 4510 display module for flexible operation.

Suitable for hazardous areas with ATEX certification, supporting signals from Zone 0/1/2 and Zone 20/21/22 environments.

This product is ideal for industrial automation, electrical signal conditioning, and hazardous area monitoring in sectors like manufacturing, oil & gas, chemical processing, and maritime industries. It provides a reliable and safe interface for transmitting pulse signals from potentially explosive environments to safe area control systems.
