Siemens 6ES7 322-5HF00-0AB0 Programmable Logic Controller Output Module

Siemens 6ES7-322-5HF00-0AB0 is a SIMATIC S7-300 eight-channel digital output module (SM 322) featuring isolated relay contacts for reliable field-device control. It plugs into a standard S7-300 rack via a 40‑pole backplane, providing galvanic isolation between the controller and the load circuits. Each of the eight relay outputs is capable of switching loads up to 5 A per channel and includes RC filter overvoltage protection to suppress transients. This module is well suited for driving solenoids, lamps, and small contactor coils in industrial automation, and it integrates with Siemens engineering workflows for straightforward wiring, monitoring, and diagnostics within a SIMATIC system.
