Siemens 6ES7422-1BH11-0AA0 SIMATIC PLC Module

Siemens 6ES7422-1BH11-0AA0 is a SIMATIC S7-400 digital output module (SM 422) with 16 channels that deliver DC 24 V outputs at up to 2 A per channel, enabling direct control of common industrial devices from an S7-400 controller. Designed for rugged factory environments, the SM 422 provides isolation between its outputs and the controller backplane to protect the PLC from load transients and prevent interference between channels. This module is intended for mounting in a SIMATIC S7-400 rack as part of the modular I/O system, enabling scalable expansion of digital output capabilities for machines, conveyors, packaging lines, and automated assembly cells. The 16 digital outputs operate at 24 V DC and support up to 2 A per output, making it suitable for driving solenoids, relays, and other actuators directly from the PLC. With 16 channels in a single module, it offers a compact solution for expanding control capabilities in medium-sized automation setups.
