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.
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.
