D5034S
SIL 3 Switch/Proximity Interface
Description
The single channel Switch/Proximity Detector Interface, D5034S, is a high integrity repeater, designed to interface contacts or proximity detectors (EN60947-5-6, NAMUR) located in Hazardous Area and is suitable for applications requiring SIL 3 level (according to IEC 61508) in safety related systems for high risk industries.Field loop integrity and status (line plus contact or proximitor) are continuously and directly monitored, in transparent mode, into the PLC, ESD, DCS using their existing input line, without requiring an additional channel for line fault detection.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.
