Siemens AG 6ES7 322-1BH01-0AA0 Digital Input Module

Siemens SM322 digital output module, 16x24V DC/0.5A (6ES7 322-1BH01-0AA0), designed for SIMATIC S7-300 systems, installs in a backplane via a 20‑pole connector to provide sixteen discrete 24 V DC outputs for driving relays, solenoids, indicator lamps, and similar actuators. The module's outputs are arranged in two eight-channel groups, with a combined maximum current of 8 A per module (4 A per group) to support typical field devices without overloading a single rail. As a DO module, it is specified as DO 16xDC24V/0.5A, and it shares the same industrial-grade rating and backplane interface that characterizes the SM322 family, making it compatible with standard SIMATIC S7-300 hardware configurations and upgrade paths. The 6ES7 322-1BH01-0AA0 variant maps to digital output functionality and is listed in Siemens catalogs and Industry Mall references as a 16-channel, 24 V DC, 0.5 A per channel output card for use in automation projects requiring reliable, modular I/O expansion. Typical applications include machine control panels, conveyor lines, packaging equipment, and other discrete control tasks where 24 V DC actuators are switched by a PLC.
