9203 – Solenoid / alarm driver

Quick Overview – 9203A:

• Universal 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 driver for the control of solenoids etc.
• 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 4511/4501).
• Selection of direct or inverted function for each channel via PR 4511/4501 and the possibility of reducing the output current to suit the application.
• Optional monitoring of the output current by way of PR 4511/4501.
• Optional redundant supply via power rail and/or separate supply.

Application:

• The device can be mounted in and transmit signals to non-classified area and zone 2.
• Control of ON / OFF solenoids, acoustic alarms and LEDs.
• The 9203A 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 9203A has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.
