Siemens SIMATIC S7-300 SM 322 High-Density Digital Output Module (6ES7 322-1BL00-0AA0)

SKU 6ES7 322-1BL00-0AA0

Compact, High-Density Switching for Industrial Automation
The Siemens SIMATIC S7-300 SM 322 (part number 6ES7 322-1BL00-0AA0) is built for automation setups requiring a high concentration of digital outputs within a standard 40 mm module width. By supporting 32 discrete output channels, it significantly reduces total rail space requirements and overall hardware costs for complex control systems.

Additional information

32 Transistor Digital Outputs: Arranged into 4 galvanically isolated groups of 8 channels operating on standard 24 V DC nominal voltage.

0.5 A Current Rating Per Channel: Delivers up to 0.5 Amperes per output (with a total group current capacity of 4.0 A), suitable for standard industrial loads like pilot lights, control relays, and pneumatic directional valves.

Integrated Circuit Protection: Built with internal electronic short-circuit protection and inductive voltage suppression to guard against reverse EMF spikes when switching inductive loads.

Galvanic Isolation: High-grade optocouplers isolate the backplane bus logic from field-side circuitry (500 V DC testing level) to protect the main central processing unit from electrical transients.

Diagnostic & Channel Visuals: Individual green LEDs for each channel provide immediate visual identification of active outputs during testing, commissioning, and routine maintenance.

High-Density Front Wiring: Designed to work with a standard 40-pole front connector (screw or spring-clamp termination).
