PR electronics 9203A Solenoid / alarm driver. Universal driver for solenoids, acoustic alarms and LEDs. 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 45xx and the possibility of reducing the output current to suit the application. Optional monitoring of the output current by way of PR 4500. Optional redundant supply via power rail and/or separate supply. 1 or 2 channels. Can be supplied separately or installed on power rail, PR 9400. SIL 2-certified via Full Assessment. 1 green and 2 yellow/red front LEDs indicate operation status and malfunction. 2.6 kVAC galvanic isolation between input, output and supply. The devices can be mounted vertically or horizontally without distance between neighbouring units.
Application
The 9203A can be mounted in the safe area and in zone 2 / Class 1, Division 2, Group A, B, C, D.
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.
Suitable for the use in systems up to Performance Level “d” according to ISO-13849.
