CMOD-01 I/O Extension Module 2RO/1DO External 24V | ABB

The Original New ABB CMOD-01 (3ABD50000004420) is a compact multifunction I/O extension module designed to expand the output capacity of ABB ACS580, ACH580, and ACQ580 drives. It adds an external 24V AC/DC supply interface and provides two relay outputs (2×RO) and one transistor output (1×DO). The module is installed directly into the drive's option slot, enabling enhanced control and monitoring capabilities without replacing the main drive.

Core Engineering Highlights:
2 relay outputs (2×RO) + 1 transistor output (1×DO) | External 24V AC/DC supply interface | Maximum contact rating: 250V AC / 30V DC / 2A | Maximum breaking capacity: 1500 VA | Power consumption: 25W at 24V DC (1.04A) | Compact design for drive option slot installation | Parameter configuration via drive parameters 15.01 and 15.02 | Compatible with ACS580, ACH580, ACQ580 drives
