DO-A3 Digital Output (6 open collector and 2 relais)

Why Choose the Yaskawa DO-A3 Digital Output Expansion Option?

The Yaskawa DO-A3 is a digital output expansion option card designed for use with Yaskawa A1000 series inverter drives. This module adds additional programmable digital output channels to the drive, allowing operating status signals and control feedback to be transmitted to PLCs, relays and other automation equipment.

By installing the DO-A3 option card, engineers can expand the drive’s signalling capabilities, enabling external systems to monitor inverter conditions such as run status, alarms, frequency level or fault events. These outputs allow the drive to communicate operational information to wider automation systems and control panels.

The compact plug-in design allows the module to be installed directly inside compatible Yaskawa drives, providing reliable digital output expansion without the need for external interface modules.
