Siemens 6ES7322-1BH01-0AA0 is a SIMATIC S7-300 digital output module (SM 322) with galvanic isolation, delivering 16 DC 24 V outputs. Each output is rated for 0.5 A, enabling direct control of 24 V loads such as solenoid coils or relays. The module uses a 1×20-pole connector and groups its outputs into two independent circuits, with a maximum of 4 A per group (8 A total per module). This combination of isolation, channel count, and current rating makes it suitable for distributing 24 VDC actuation signals in compact S7-300 configurations and it is designed to operate with SIMATIC S7-300 CPUs and expansion racks.
