6ES7422-5EH10-0AA0 - Digital Output Module - SIEMENS

SIEMENS 6ES7422-5EH10-0AA0, 16 DO digital output module for SIMATIC S7-400

Designed for demanding industrial environments, the 6ES7422-5EH10-0AA0 meets the needs of operators controlling DC actuators at elevated voltages. This digital output module integrates directly into SIMATIC S7-400 controllers and provides 16 isolated outputs with a 20 to 125 V DC range and 1.5 A per channel. It is aimed at maintenance teams, automation engineers and integrators seeking a reliable solution to switch DC loads while protecting the I/O architecture and reducing mean time to repair. Integrated diagnostics give immediate visibility of channel and group status, speeding up fault analysis. The 8-points-per-common layout simplifies wiring, load segregation and power distribution. With this module you standardize references, keep your equipment operational and secure service continuity.

Tangible benefits for line availability

• 20 to 125 V DC range – A single card covers many DC applications, reducing the number of variants to stock and easing fleet standardization.
• 1.5 A per output – Drive capacity suited to common DC actuators, reducing the need for interface relays and lowering wiring complexity.
• Isolated outputs – Enhanced protection for the controller and bus, reduced disturbance feedback, and improved overall system robustness.
• Integrated diagnostics – Status and fault indicators usable by maintenance to quickly locate defects, reduce MTTR and improve OEE.
• 8 points per common – Clear structuring of power circuits, streamlined wiring and easier maintenance during interventions on defined groups.

Key technical features and build quality

The 6ES7422-5EH10-0AA0 provides 16 isolated digital outputs, organized in two groups of 8 points per common for controlled power distribution. The output voltage range spans 20 to 125 V DC, allowing control of DC loads on industrial networks where voltages above 24 V are required. Each channel can deliver up to 1.5 A, a rating suitable for many automation applications. The module includes diagnostic functions, delivering clear feedback to the controller along with local indications to speed up inspection and maintenance tasks. Fully compatible with the SIMATIC S7-400 range, it fits into existing architectures without complex software adaptation. The SIEMENS design, known for its reliability, ensures stable performance and coherent integration within digital I/O systems for continuous industrial applications.

Recommended uses and integration contexts

This module is intended for installations that require control of DC actuators at higher voltages, for example in continuous processes, energy management, water treatment or industrial infrastructure. It is suitable for production lines needing clear segmentation of output groups, for upgrading existing S7-400 cabinets or for one-to-one replacements of a failed card. Maintenance teams will benefit from diagnostics for fast troubleshooting and safe restoration to service.

Differentiation, operational safety and expert support

The value of the 6ES7422-5EH10-0AA0 lies in the combination of a wide voltage range, 1.5 A per channel and integrated diagnostics, all in the S7-400 form factor and standards.
