The ABB RDCO-01C (64606948) is a DDCS (Distributed Drives Communication System) communication option module designed as an add-on for RMIO motor control/I/O boards (or RDCU/BCU control units) in ABB drives. It supports factory installation or retrofitting, and includes connectors for four fiber optic DDCS channels (CH0-CH3) — typically assigned to overriding systems, I/O options, master/follower links, and PC tools (for ACS800 drives), with channel usage defined by the drive’s application program.
Equipped with 24V DC (±10%) power supply support, this module operates with <5W typical power consumption (200mA @ 24V DC) and offers communication speeds up to 12Mbps via ST/BFOC optical interfaces (compatible with POF/HCS cables). The "C" suffix indicates a conformal-coated circuit board, enhancing resistance to moisture, dust, and corrosion. It functions reliably across 0°C to +55°C operating temperatures and -40°C to +85°C storage conditions, with 5-95% non-condensing humidity tolerance.
