PR Electronics 9203B – Solenoid / Alarm Driver

Advanced features

  • The device features a universal intrinsically safe (I.S.) driver capable of controlling solenoids and similar devices, supporting various I.S. data through three integrated I.S. barriers.
  • Two hardware configurations offer a choice between Low (35 mA) and High (60 mA) current outputs.
  • Configuration and monitoring are facilitated via a detachable display front (PR 45xx).
  • Each channel can be set to operate in direct or inverted mode using the PR 45xx interface, with the option to adjust output current to suit hazardous area requirements.
  • Optional monitoring of output current to the hazardous area is available through PR 45xx.
  • Redundant power supply options include power rail and/or separate supply.

Application:

  • PR Electronics 9203B can be installed in safe areas or Zone 2 / Class 1, Division 2 areas, transmitting signals to Zone 0, 1, 2 and Zone 20, 21, 22, including M1 mining / Class I/II/III, Div. 1, Gr. A-G.
  • It serves as a driver for controlling ON/OFF solenoids, acoustic alarms, and LEDs in safe or hazardous areas.
  • Control inputs include NPN/PNP signals or switch signals.
  • Internal error events can be monitored via individual status relays or a collective electronic signal via the power rail.
  • PR Electronics 9203B is designed, developed, and certified for SIL 2 applications according to IEC 61508 standards.
  • It is suitable for systems up to Performance Level “d” according to ISO-13849.

Technical Characteristics:

  • Front indicators include 1 green LED and 2 yellow/red LEDs to indicate operational status and malfunctions.
  • Galvanic isolation of 2.6 kVAC between input, output, and supply ensures safety.

Mounting:

  • The devices support vertical or horizontal mounting without requiring distance between adjacent units.
