Solenoid/alarm driver 9203B

Advanced features

• Universal I.S. driver for the control of solenoids etc., with various I.S. data by way of three built-in I.S. barriers.
• Two hardware versions make it possible to choose either Low (35 mA) or High (60 mA) current output.
• Configuration and monitoring by way of detachable display front (PR 4500).
• Selection of direct or inverted function for each channel via PR 4500 and the possibility of reducing the output current to the hazardous area to suit the application.
• Optional monitoring of the output current to the hazardous area by way of PR 4500.
• Optional redundant supply via power rail and/or separate supply.

Application

• 9203B can be mounted in the safe area or in zone 2 / Class 1, Division 2 and transmit signals to zone 0, 1, 2, and zone 20, 21, 22, including M1 mining / Class I/II/III, Div. 1, Gr. A-G.
• Driver for controlling ON / OFF solenoids, acoustic alarms, and LEDs mounted in safe or hazardous areas.
• The 9203B is controlled by an NPN/PNP signal or a switch signal.
• Monitoring of internal error events via the individual status relay and/or a collective electronic signal via the power rail.
• The 9203B has been designed, developed, and certified for use in SIL 2 applications according to the requirements of IEC 61508.
• Suitable for use in systems up to Performance Level “d” according to ISO-13849.

Technical characteristics

• 1 green and 2 yellow/red front LEDs indicate operation status and malfunction.
• 2.6 kVAC galvanic isolation between input, output, and supply.
