ABB RDCO-04C 68882915 Communications Interface Board

ABB RDCO-04C 68882915 Communications Interface Board is a DDCS communication option module for ABB ACS880 drive packages, designed to add fiber‑optic interface capability to the control electronics. The module is installed on the BCU control unit in the 1×R8i frame size and is used to link distributed drive components through a fiber network, enabling data exchange and command communication across the RDCO system. The kit requires external fiber optic cabling to interconnect with supply/inverter modules and LCL filters; approved data cables include NLWC-02 (2 m), NLWC-03 (3 m), NLWC-05 (5 m), NLWC-07 (7 m), and NLWC-10 (10 m) pairs with connectors, and one cable pair is needed for each module and for connections between two RDCO-04C options. The RDCO-04C module does not include the control circuit plug connector X50, which must be ordered separately, while the X51, X52 and X53 connectors are included in the module kit. Made in Finland, the RDCO-04C 68882915 is the designated option module to enable the DDCS communication path within ABB’s drive architecture, supporting reliable, high‑speed data transfer between the BCU and connected drive components for coordinated control of the automation system.
