ABB RDCU-12C 3AUA0000036521 Relay output control module
ABB RDCU - 12C 3AUA0000036521 is a control unit for the ACS800 series of inverters. In ACS800 motor drive applications, it assigns different functions to analog and digital I/O channels, such as control, monitoring, and measurement (e.g., motor temperature). By providing additional analog and digital I/O connections, relay outputs, etc., this control unit can expand the I/O functionality of the ACS800 drive.
