SIL 3 SWITCH/PROXIMITY DETECTOR REPEATER TRANSISTOR OUT DESCRIPTION The dual channel Switch/Proximity Detector Repeater D6031D module is a unit suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries. The unit can be configured for switch or proximity detector (EN60947-5-6, NAMUR), NO or NC and for NO or NC optocoupled open collector transistor output. Each channel enables a load to be controlled by a switch, or a proximity detector. Fault detection circuit (DIP switch configurable) is available for both proximity sensor and switch equipped with end of line resistors. In case of fault, when enabled it de-energizes the corresponding output transistor and turns the fault LED on; when disabled the corresponding output transistor repeats the input line open or closed status as configured. D6031D is programmable via dip switches as single input and two independent outputs. Out 2 can be programmed for output duplicating Out 1 or fault detection Out. In case of duplication, transistor driving can be independently configured for each output. In case of fault output, transistor driving can be programmed as normally closed (NC) or normally open (NO). Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.
