PR electronics 9203B Solenoid / alarm driver. Universal Ex driver for solenoids, acoustic alarms and LEDs. 1 or 2 channels. 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 the control of ON / OFF solenoids, acustic alarms and LEDs mounted in safe or hazardous area.
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 the 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.
