Solenoid / alarm driver

PR-9203B

Universal Ex driver for solenoids, acoustic alarms and LEDs
Extended self-diagnostics
1 or 2 channels
Can be supplied separately or installed on power rail, PR 9400
SIL 2-certified via Full Assessment

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.
