Siemens 6ES7322-1BL00-0AA0 Digital Output Module

Siemens 6ES7322-1BL00-0AA0 SM322 digital output module provides 32 discrete transistor (PNP) outputs at 24 VDC for driving field devices in SIMATIC S7-300 systems. It functions as an I/O expansion or replacement in factory and process automation, driving solenoids, contactors, indicator lights, relays, and other DC loads controlled by PLC logic; common applications include conveyors, packaging machinery, assembly lines, material handling systems, and machine tools. Key specs: 32 outputs, 0.5 A per channel (typical), spring-clip or screw terminal connections, mounting in a SIMATIC S7-300 rack slot, output status LEDs, and fast transistor switching; total current load is platform dependent and protection includes short-circuit and overload protection (platform dependent). Operates in industrial temperature ranges and is designed to drive discrete DC loads from PLC logic, with common replacement option Siemens 6ES7322-1BH01-0AA0.
