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.
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.
Mounting
- The devices can be mounted vertically or horizontally without distance between neighbouring units.
