Siemens 6ES7422-1BL00-0AA0 Digital Output Module

Product Description

The Siemens 6ES7422-1BL00-0AA0 is a 32-channel digital output module from the S7‑400 series, designed to control actuators including relays, solenoids, and indicator lamps. Its compact architecture provides high channel density, making it ideal for large-scale automation installations where space optimization is critical.

Each output channel operates at 24 V DC with a maximum current of 0.5 A, using a current-sourcing (PNP) configuration. Galvanic isolation between channels and the backplane bus ensures system safety and prevents interference, while integrated LED indicators provide real-time diagnostics for each output channel, facilitating quick troubleshooting.

This module occupies 4 bytes of address space and is engineered for industrial environments, offering robust and reliable performance in continuous operation. Its compact design allows multiple modules to fit efficiently within S7‑400 racks.
