Overview
The 6ES7222-5HH50-0XB0 is a Siemens SM 1222 digital output module for the S7-1200 G2 system, providing 16 relay outputs rated at 2 A per channel. It measures 150 x 47 x 110 mm and weighs 266 g, fitting the standard S7-1200 module footprint.
Function & operation
Each of the 16 relay outputs switches loads up to 2 A, suitable for solenoid valves, contactors, and indicator lamps. The relay isolation separates the field wiring from the backplane, simplifying troubleshooting on a machine line.
Applications
This module is used in S7-1200 G2-based machine control for packaging, material handling, and assembly stations where discrete on/off control of actuators is required.
