Siemens 6ES7422-1FH00-0AA0 Digital Output Module – SIMATIC S7-400 Series
When a digital output module fails on a production line, the consequences are immediate and severe: actuators freeze, conveyor belts stop, robotic arms halt mid-cycle, and entire manufacturing cells go dark. Every minute of unplanned downtime costs thousands of dollars in lost output, emergency labor, and potential product scrap. The Siemens 6ES7422-1FH00-0AA0 is the critical link between your S7-400 controller and the physical world — without it, your automation system simply cannot act.
The 6ES7422-1FH00-0AA0 is a 16-channel 24 VDC digital output module purpose-built for the SIMATIC S7-400 platform — Siemens’ flagship high-performance PLC series designed for demanding process and manufacturing automation. Within the S7-400 family, this module occupies the mid-range output tier, offering a balance of channel density, current capacity (2 A per channel), and diagnostic capability that makes it the go-to choice for machine builders and system integrators worldwide. The S7-400 platform powers critical infrastructure across automotive, chemical, oil & gas, and heavy industry sectors globally, and this module is one of its most widely deployed I/O components.

Frequently Asked Questions
Q: Is the 6ES7422-1FH00-0AA0 compatible with both STEP 7 and TIA Portal?
A: Yes. This module is fully supported in STEP 7 V5.x (classic) and TIA Portal V13 and later. The hardware catalog entry is available in both environments.
Q: Can this module be used in a redundant S7-400H system?
A: The 6ES7422-1FH00-0AA0 is a standard (non-F, non-H) output module. It can be used in the standard I/O racks of an S7-400H system but is not a redundant or fail-safe module itself.
Q: What is the difference between 6ES7422-1FH00-0AA0 and 6ES7422-1BL00-0AA0?
A: The 1FH00 variant provides 16 channels at 24 VDC / 2 A (transistor output), while the 1BL00 variant offers 32 channels at 24 VDC / 0.5 A. Choose 1FH00 for higher current loads per channel; choose 1BL00 for higher channel density with lighter loads.
Q: Do you supply new, refurbished, or surplus units?
A: We supply both new (factory-sealed) and tested surplus units depending on availability. The condition is clearly stated in our quotation. All units pass our QA process regardless of condition.
Q: What is the typical lead time?
A: In-stock units ship within 2–5 business days internationally. For sourced units, lead time is typically 7–15 business days. We confirm exact lead time in the quotation.
Q: Can I get a datasheet or technical documentation?
A: Yes. Contact us at support@konmask.com and we will provide the official Siemens datasheet and, where applicable, our test report.
