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.","metaTitle":"Siemens 6ES7522-5HH00-0AB0 S7-1500 16 Relay Output Module DQ","metaDescription":"16 relay outputs, DQ and MSO enabled.
