Frequently Asked Questions
How can I verify the exact module identity?
Confirm the nameplate order number 6ES7422-1BL00-0AA0 and the SIMATIC S7-400 SM 422 designation.
What load voltage and output current does this module use?
Rated load voltage L+ is 24 V DC, with a permissible range of 20.4 V to 28.8 V DC. Signal "1" output current is 0.5 A rated value.
Does the module provide short-circuit protection?
Yes. Short-circuit protection is clocked electronically.
Does it provide channel-to-channel potential separation?
No. There is no potential separation between the channels; potential separation between the channels and the backplane bus is provided.
