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, each rated at 0.5 A, for direct control of loads such as solenoids and relays. The module uses a single 20-pole interface and offers galvanic isolation between the controller and the loads, protecting the CPU from faults and transients on the output side. Outputs are organized in two groups of eight, with a per-group current rating of 4 A (8 A total for the module). Designed for the SIMATIC S7-300 family, this SM 322 module enables parallel switching of multiple 24 V devices from one CPU, delivering reliable, discrete control in machine automation environments.
