PR Electronics 9200 Series Pulse Isolator Switch Input Relay Output 19.2V dc 31.2V dc Supply ATEX 9202B1A

PR Electronics 9202B1A Pulse Isolator from the 9200 series is a robust single-channel signal conditioning device designed for isolation and safe signal transmission in hazardous environments. It accepts switch input signals and provides relay output, ensuring safe operation and signal integrity through advanced galvanic isolation technology rated at 2.6 kV ac between input, output, and power terminals. This isolation guarantees that input pulses from sensors are electrically separated from output pulses, enhancing system safety.

Powered by a dual DC supply voltage of 19.2 V and 31.2 V, this isolator is suitable for applications requiring intrinsic safety, such as installation in zone 0 and Division 1 explosion-risk areas. The 9202B1A complies with ATEX certification standards and is designed according to SIL 2 requirements under IEC 61508, making it appropriate for safety-instrumented systems in industrial, manufacturing, water treatment, and process automation sectors.

The device mounts easily on DIN rails and features screw-type terminals for secure connections. It is rated IP20 for protection against foreign objects and has an operating temperature range from -20°C to 60°C, ensuring stable performance in diverse environmental conditions.

Advanced monitoring capabilities include self-diagnostics for cable faults and error events, with status relays signaling issues directly. It offers configurable input-output functions (direct or inverted), programmable via a detachable display module (PR 4510), facilitating user-friendly calibration and diagnostics.

This pulse isolator uses transformer and optical isolation techniques, creating a galvanic barrier that limits energy to prevent ignition in explosive atmospheres, even if sensors or cables are compromised. Typical applications encompass electrical automation, signal conditioning, industrial process safety, and hazardous area instrumentation.

Provides 2.6kV galvanic isolation between input, output, and supply terminals. Operates on 19.2 V dc and 31.2 V dc supply voltages. DIN rail mountable with screw terminals for reliable installation. Certified ATEX and SIL 2 compliant for intrinsic safety and functional safety.

Extended self-diagnostics including cable fault detection and status indication. Configurable via detachable programming display module for ease of use. Front LEDs indicate operational status and malfunctions. Suitable for transmission of signals from hazardous area sensors to safe areas.

Operating temperature range of -20°C to 60°C for wide environmental compatibility. Ideal for industrial, laboratory, electrical automation, and hazardous area use cases.
