Banner Engineering MSCA-1 Mini-Screen Light Curtain Control Box

Banner Engineering's MSCA-1 Mini-Screen Light Curtain Control Box is the metal enclosure controller for the MINI-SCREEN safety light curtain system, consolidating power, control, and diagnostics in a single unit. Identified as Part No. 39022, it operates from a 115 V AC supply (50/60 Hz) and draws about 400 mA, delivering a trip-type output to the safety circuit. A built-in diagnostic display and status LEDs show RUN, BLOCKED, CLEAR, RESET, LOCKOUT, BLANKING, and ALIGNMENT, with support for 2-beam floating blanking to accommodate small-passage scenarios, and a defined-beam spacing of 0.5 inches (12.7 mm) between adjacent beams. The enclosure is UL/CSA Type 13 and IP64 rated, and features a 500 mA, 250 V AC fuse, a operating temperature range of 0°C to 50°C, and an auxiliary contact rated 10 VA at 125 V AC/DC (500 mA), plus an SSD rating of 230 V AC, 4 A resistive. Banner notes that MINI-SCREEN controllers are no longer available for purchase and that the MSCA-1 is considered obsolete, reflecting the system’s long-standing design as a safety-control module within industrial light curtain installations.
