Product Overview
The Siemens SIMATIC S7-400 digital output module SM 422, part number 6ES7422-1HH00-0AA0, provides 16 isolated relay outputs rated for 5 A at up to 230 V AC or 60 V DC. It is designed for rack-based installation within S7-400 control systems and serves to switch high-load devices such as contactors, lamps, or motor starters. Typical use cases include industrial machinery control, process automation, and distributed control schemes requiring galvanic isolation between control logic and load circuit.
