Banner Engineering 43296 RS-232 Mini-Array MAC 1 Controller

The Banner Engineering MAC-1 MINI-ARRAY Controller (P/N 43296) is a compact, 16–30 VDC powered interface that sits at the heart of Banner’s MINI-ARRAY measuring light curtain system, handling power, logic, and data communications with the rest of the safety architecture via RS-232 and RS-485 serial outputs. It provides two outputs: Output 1 is a discrete reed-relay suitable for signaling and interlock circuits, while Output 2 is a solid-state NPN transistor output that can drive logical inputs in a PLC or safety controller. The MAC-1 measures about 110 x 100 x 75 mm (4.3 x 3.9 x 3.0 in) and is intended for mounting in typical industrial control panels; it works with MINI-ARRAY transmitters and receivers to implement a measuring light curtain safety system that provides a clear interface for machine guarding logic. The RS-232 and RS-485 serial data outputs support data transfer to a host, PLC, or logging device, enabling monitoring of beam status, event timing, and integration with broader safety or automation systems.
