- Customer I/O power supply identified by ABB as spare part 3HAC12934-1
- Documented 24 V source for DeviceNet and customer-power circuits
- IRC5 service connection sequence covering X1 through X9
DSQC 608 3HAC12934-1 supplies the customer-side I/O power function in documented ABB IRC5 controller configurations.
Its role includes the 24 V power paths shown for DeviceNet hardware and customer circuits, making circuit identification essential before any exchange.
Confirm the cabinet build, label X1 through X9 and review whether the installed controller uses ABB's later DSQC 609 arrangement before reconnecting field power.
