Digital input module D6231E

Modbus RTUUSBserial

SIL 2 SWITCH/PROXIMITY DETECTOR REPEATER O.C. OUT DESCRIPTION The Switch/Proximity Detector Repeater type D6231E is a unit with eight independent channels suitable for applications requiring SIL 2 level (according to IEC 61511) 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 input and for NO or NC floating solid-state relay (photo-MOS) isolated output compatible with logic circuits. Configuration is programmable from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software. Each channel enables a load to be controlled by a switch, or a proximity detector. Fault detection circuit (configurable by PC) is available for all proximity sensors and switches equipped with end of line resistors. In case of fault, when enabled it de-energizes the corresponding solid-state relay (photo-MOS) and turns the fault red LED on; when disabled the corresponding solid-state relay (photo-MOS) repeats the input line open or closed status as configured. D6231E has eight inputs and eight independent outputs. Modbus RTU RS-485 output is available on Bus connector. Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.
