Siemens 6ES7222-1HH32-0XB0 SIMATIC S7-1200 Digital Output SM 1222 Module 16DO 2A
The Siemens 6ES7222-1HH32-0XB0 is a versatile digital relay output module from the SIMATIC S7-1200 programmable logic controller (PLC) family, designed to directly switch AC and DC loads such as contactors, solenoid valves, indicator lamps, small motors, and heaters. With 16 isolated relay outputs, each rated for up to 2 A at 250 V AC or 30 V DC, this module delivers exceptional flexibility for machine builders and system integrators in industries like packaging, material handling, food & beverage, building automation, and test equipment.
Unlike transistor-based outputs, the 6ES7222-1HH32-0XB0 uses electromechanical relays, enabling it to switch both AC and DC circuits, handle inrush currents, and provide galvanic isolation between the control logic and field devices—making it ideal for applications requiring high voltage compatibility, bidirectional switching, or interfacing with legacy systems.
