Banner Engineering SFCDT-4A1C Fiber Optic Sensor Safety Controller

Banner Engineering's PICO-GUARD SFCDT-4A1C Fiber Optic Safety Controller is the four-channel hub of the PICO-GUARD fiber optic safety system. It operates on 24 V DC and monitors four optical channels for beam interruption, then drives two PNP OSSD safety outputs to control guarding devices while exposing seven PNP auxiliary outputs for fault and channel status signaling. The controller accepts two USSI input groups (two NC USSI inputs per group, for four total) to handle stop/reset signaling and system interlocks, and provides RS-232 diagnostics for remote monitoring. This model is documented as part of Banner's Pico-Guard family, with European declarations of conformity published for PICO-GUARD configurations in hazardous environments (ATEX) and optical units capable of supporting II 1 G and II 3 D classifications when used with appropriate hardware. The SFCDT-4A1C is featured in Banner installation and application literature alongside two-channel EDM configurations and system-interface guidance, underscoring its role as a dedicated fiber-optic safety controller that coordinates channel-by-channel safety outputs across the four sensing paths.
