ABB 3HNE 00025-1 Remote Servo Control Module DSQC350

ABB DSQC350 Remote Servo Control Module, 3HNE00025-1, is a DSQC 350-series remote I/O unit designed to interface ABB S4C/S4C+ robot controllers with the Interbus-S fieldbus as a slave device. As a remote I/O module, it expands the controller's I/O capabilities by transmitting and receiving discrete signals over the Interbus-S network. In ABB's DSQC 350 family, the 3HNE-00025-1 designation corresponds to the standard remote I/O unit used for Interbus-S follower/servo control interfaces. The module is listed by ABB's documentation as a Remote I/O Unit on the DSQC 350 platform, and distributor listings show multiple sub-variants (e.g., 3HNE00025-1/13) that indicate revision-level options. Typical applications include expanding I/O for ABB S4C/S4C+ installations, enabling integration with sensors, actuators, and servo feedback devices via Interbus-S, and providing a remote gateway for control signals between the robot controller and field devices. Designed for Interbus-S communication, the DSQC350 remote servo control module serves as a slave device that relays control commands and status signals between the ABB controller and remote hardware, helping to simplify wiring and improve fault isolation in complex automation setups.
