Product details

Sibling check — 6ES7522-1BL10-0AA0

The 6ES7522-5EH00-0AB0: The 1BL10 packs 32 channels at 24 V DC only, no MSO, no SIL rating. The 5EH00 gives you 8 channels (typical for 5EH prefix) with MSO, SIL2, and acceptance of 48 V AC/DC and 125 V DC. If your panel was wired around the 1BL10’s 24 V COM and you need safety-rated outputs or higher pilot voltages, the 5EH00 won’t drop in without understanding the voltage group change. Channel count and wiring topology differ — verify the backplane bus allocation before swapping.

Lifecycle is marked current — no phase-out or NRND flag. Firmware V1.0.0 ships; updates are possible. Hardware functional status FS02. This module will be around for the normal S7-1500 product cycle, so it’s safe to freeze into the BOM.

Frequently asked questions

What does DQ Yes and MSO Yes mean on this module?

DQ Yes means it is a digital output module; MSO Yes indicates support for Mixed Signal Output (MSO) function, allowing the module to handle mixed voltage levels and signal types.

Will 6ES7522-5EH00-0AB0 drop into a panel specified for 6ES7522-1BL10-0AA0?

No. The 1BL10 is a 32-channel 24 V DC output without MSO or SIL2; the 5EH00 has wider voltage support and safety rating but fewer channels. Rewiring and bus reconfiguration would be required.
