Industrial MC6DC-1016-SC1 Safety Mat Controller

The MC6DC-1016-SC1 is a 24 VDC safety-mat controller from Omron STI designed to guard machine access by integrating with STI four‑wire safety mats. This DC variant of the MC6 uses relay safety outputs (OSSDs) and supports connecting up to six mats to a single controller. Two normally open safety outputs are available across TB1 positions 1, 2, 4 and 5, while one normally closed output covers TB1 positions 2 and 3. The DC version can be configured for either relay or solid‑state outputs, and this model designation indicates relay-type OSSD outputs. Power is supplied from 24 VDC, and the unit includes a two‑digit diagnostic display plus Mat Clear (green) and Machine Run (green) indicators visible on the enclosure to communicate status. It is a Category 3 safety device under EN 954‑1, with CE compliance applicable when used with STI UM series safety mats. For practical deployment, STI notes these mats and the MC6 controller are used to guard perimeter access around robots, work cells, and automated equipment, enabling safer productivity with minimal downtime.
