Siemens 6ES7 322-1BL00-0AA0 is a SIMATIC S7-300 digital output module (SM 322) offering 32 DC outputs at 24 V with a rated 0.5 A per channel, designed to switch loads such as relays, solenoids, and indicator devices in industrial automation. The module is isolated from the backplane and channels, and it plugs into an S7-300 rack via a 40-pin backplane interface, with outputs grouped in eight-channel sets and a total current rating of 4 A per group (16 A per module) to support applications requiring multiple concurrent outputs.
