Siemens 6ES7 322-1BL00-0AA0 Digital Input Module

Siemens SM322 digital output module, part number 6ES7 322-1BL00-0AA0, provides 32 independent 24 V DC outputs for the SIMATIC S7-300 family. Each output is rated for 0.5 A, giving a total module current capacity of up to 16 A, and it uses a single 40‑pole backplane interface for mounting in the S7-300 rack. The 0AA0 suffix identifies the standard, non‑redundant variant of the module. This 32‑channel output block is designed to switch binary loads such as relays, contactors, solenoids, and other 24 V DC actuators, making it suitable for expanding control capabilities in automation tasks like conveyors, machine tools, and packaging lines. It is commonly used in mixed I/O configurations alongside input modules to tailor channel count and wiring to the application’s requirements.
