The GMI D1031Q is a high-integrity, single-channel Switch/Proximity Detector Repeater designed for demanding safety applications. It acts as an intrinsic safety barrier, providing a fully floating, intrinsically safe power supply for sensors like NAMUR proximity detectors or mechanical switches located in hazardous areas. The module accurately repeats the status of the sensor to the safe area through two isolated SPST relay contacts (one normally open, one normally closed). Certified for SIL 3 applications according to IEC 61508, the D1031Q ensures reliable signal transmission and safety isolation between hazardous and safe zones. Its slim, DIN rail mountable design makes it ideal for integration into modern control system cabinets.
