Siemens 6ES7322-1BH01-0AA0 Digital Output Module

Siemens 6ES7322-1BH01-0AA0 is a SIMATIC S7-300 digital output module (SM 322) that provides 16 isolated DC 24 V outputs at 0.5 A per channel. The outputs are galvanically isolated from the processor and from one another, helping protect the PLC and peripherals in demanding industrial environments. The module uses a 1x 20-pole terminal interface and is designed for use inside a SIMATIC S7-300 I/O rack, expanding digital control capability of the system. With a total current rating of 4 A per group and 8 A maximum per module, it supports multiple simultaneous actuator loads while maintaining module-level protection. The 24 V DC output specification defines the operating range for connected devices, and the 16-channel configuration simplifies wiring and diagnostics for compact control cabinets. This SM 322 module is part of Siemens' broader S7-300 family, enabling scalable, modular automation architecture for manufacturing, packaging, and process control tasks that require reliable, isolated digital outputs in a commonly used PLC ecosystem.
