The Eaton FAK-S/KC11/I is a compact relay interface module designed to provide electrical isolation and signal conversion between control devices and field loads. It acts as an intermediary, typically taking a control signal from a PLC, sensor, or controller (input side) and using it to switch a separate, isolated load circuit (output side). The "KC11" designation indicates a versatile input that can accept a wide range of AC or DC control voltages, and a single-pole, double-throw (SPDT) relay output. This makes it ideal for tasks such as amplifying control signals, isolating sensitive electronics from noisy loads, and interfacing different voltage levels in industrial control panels.
