ABB DSQC658 3HAC025779-001 DeviceNet Communication Board

The ABB DSQC658 3HAC025779-001, also cataloged as the DSQC658 DeviceNet Communication Board, operates as a dedicated hardware component for Master/Slave bus interfacing within IRC5 Robot Controller architectures.

Hardware Specifications

ABB Backplane Bus & Network Integration

The DSQC658 card executes real-time data frame transmission over deterministically timed backplane interfaces to minimize processing overhead inside the IRC5 robot controller. Onboard hardware logic scales I/O density while regulating fieldbus bandwidth across external PLC nodes, smart sensors, and distribution blocks. Integrated physical layer circuits maintain protocol timing stability and firmware flash compatibility during high-speed master and slave bus operations.

Frequently Asked Questions

Q: How does the DSQC658 maintain program state data during external power interruption?

A: The board routes retention voltage through internal Flash memory backed by a dedicated battery circuit, preserving user configurations and network addresses during power loss.

Q: What are the electrical drive limits for the onboard digital outputs?

A: The board provides 8 digital output channels operating at 24 VDC, with each individual channel rated for a maximum continuous load current of 0.5 A.

Field Installation Guidelines

Mount the DSQC658 directly into the designated slot of the IRC5 controller cabinet or secure it onto a standard DIN rail. Connect the 24 VDC auxiliary power supply before energizing the backplane interface. Route all DeviceNet signal lines through shielded twisted-pair cables, terminating the network ends with standard 120 ohm resistors to suppress line reflections. Ensure proper single-point grounding of the cable shield to the cabinet earth bar to reduce electromagnetic interference. Verify diagnostic LED states upon power-up: solid lights indicate correct supply voltages, normal running state, and active fieldbus communication without fault conditions.
