Product details

Module in the kit

The 6ES7522-5HH00-0AB0: No special accessories needed for basic rack mounting; the module occupies standard S7-1500 slot spacing. Typical power loss is 5 W.

Diagnostics in detail

DQ (diagnostics qualified) means the module generates diagnostic alarms on channel faults. MSO (maintenance support) raises maintenance interrupts. Both are active here, minimizing blind troubleshooting. A red ERROR LED and yellow MAINT LED indicate state at a glance; each output channel has a green status LED. Isolation tested at 3 100 V DC between channels and between channels and backplane bus, and 707 V DC type test between L+ and backplane bus. Cable lengths: shielded up to 1 000 m, unshielded up to 600 m.

Frequently asked questions

What does DQ mean on this module?

DQ (diagnostics qualified) is enabled, so the module can report diagnostic alarms on channel faults, simplifying fault isolation.

What does MSO mean on this module?

MSO (maintenance support) is enabled, meaning the module raises maintenance interrupts to the controller for preventive alerts.
