The ABB S2C-A1S is a compact, universal coil voltage, plug-in signal relay from ABB's extensive S-series of industrial control relays. It is a member of the popular "ice-cube" relay family, renowned for its standardized footprint and reliable switching. This specific model is defined by its single-pole, double-throw (SPDT) contact configuration and a universal AC/DC coil. The suffix "A1S" indicates a specific coil terminal arrangement and possibly a low-power, signal-level switching variant.
