Siemens 6ES7 322-1BF01-0AA0 Digital Output Module

Siemens 6ES7 322-1BF01-0AA0 Digital Output Module is an eight-channel digital output module (SM322) for SIMATIC S7-300 systems, delivering eight 24 V DC outputs rated up to 2 A per channel. The outputs are optically isolated from the backplane to protect the controller and field devices when switching DC loads, and the unit uses a 20-pole interface connector for field wiring in SIMATIC S7-300 racks. The exact part number 6ES7 322-1BF01-0AA0 identifies an SM322, 8 DO, 24 V DC, 2 A per output setup, designed for use within the SIMATIC S7-300 family. This module is widely used to drive DC loads such as relay coils and other 24 V devices, providing reliable, isolated switching across all eight channels while integrating with the standard S7-300 backplane architecture.
