ABB 1SAP170800R0001 - CM578-CN CANopen Module (AC500)

The ABB 1SAP170800R0001 is the order code for the CM578-CN communication module: a CANopen interface for AC500 PLC systems, described by distributors with a pluggable 5-pole spring-contact terminal and 24 VDC supply. Listings across major distributors show consistent descriptions, international stock and warranty options, and refurbished units are offered by specialist dealers. Use CM578-CN to connect CANopen devices such as drives, actuators and remote I/O to an AC500 CPU.
