Siemens 6ES7422-1BH11-0AA0 Analog Input Module

Siemens 6ES7422-1BH11-0AA0 is a SIMATIC S7-400 digital output module (SM 422) that provides 16 x DC 24 V output channels, each capable of delivering up to 2 A. It mounts in a SIMATIC S7-400 rack and interfaces with the CPU over the backplane to switch external 24 V loads such as relays, contactors, lamps, and other actuators. With 16 independent outputs, this DO16 module is the 16-channel variant of the SM 422 family, enabling scalable control of multiple loads from a single module. The part number 6ES7422-1BH11-0AA0 corresponds to the DO16 24 V DC/2 A configuration, designed for industrial automation applications using the S7-400 platform.
