Product Overview
Applications
The outputs can control a digital input.
Two outputs can provide redundant control of a load, using only outputs from the same group.

Frequently Asked Questions
What is Siemens 6ES7422-1BH11-0AA0?
It is a SIMATIC S7-400 SM 422 digital output module with isolated 16 DO.
What load voltage and output current does this module have?
The rated load voltage is 24 V DC, with a permissible range from 20.4 V to 28.8 V. Signal "1" output current is rated at 2 A, with a permissible range from 5 mA to 2.4 A.
Can the outputs be switched in parallel for redundant load control?
Yes; redundant load control is possible only with outputs from the same group. Parallel switching for uprating is not possible.
What configuration details should be included with a quotation request?
Provide the requested quantity, destination, schedule, and any additional BOM lines together with the exact order number 6ES7422-1BH11-0AA0.
