Siemens AG 6ES7 322-1BH00-0AA0 Digital Output Module is a SIMATIC S7-300 SM322 card that provides 16 digital outputs at 24 V DC. Each output channel is rated for 0.5 A, and the module accommodates two output groups with a total current rating of 8 A (4 A per group). The 16 outputs are galvanically isolated from the backplane, and the module uses a 20-pin wiring connector for field connections. Designed for installation in SIMATIC S7-300 backplanes, this DO module is commonly used to switch DC loads such as relay coils and other 24 V actuators in automation and production-line equipment.
