ABB 3HAC026253-001 Power Supply

The ABB DSQC661 Power Supply (Part Number 3HAC026253-001, Rev. 06) is a stabilized 24V DC power-backbone module designed for ABB's IRC5 robot controller platform, delivering the 24V power and 32 configurable I/O channels that drive the controller and connected peripherals. It provides 16 digital inputs and 16 digital outputs (24V DC, sinking/sourcing inputs and 24V DC sourcing outputs) with a maximum of 0.5 A per channel and communicates via DeviceNet with a configurable node address set by rotary switches. The module draws its 24V DC power from the controller to form the backbone for logic and I/O, and it features 500 V AC isolation between field and system sides for safety. In terms of physical specs, the unit weighs 2.46 kg and measures 235 mm in depth and 104 mm in height, with a removable terminal block for connections. This power supply module is intended as a spare/replace component within ABB’s IRC5 robot controller ecosystem to support reliable operation of peripheral devices and safety interfaces in automated work cells.
