Product Introduction
The ABB DO561 1TNE968902R2201 Digital Output Module is a robust and versatile output module engineered for use within ABB’s AC500 programmable logic controller (PLC) systems. Designed to provide high-speed, reliable digital output control, the DO561 supports a wide range of industrial automation applications, making it an essential building block for advanced PLC-based control architectures.
The module offers 16 digital outputs, allowing it to control field devices such as relays, contactors, valves, actuators, lights, alarms, and other discrete equipment. Outputs are designed for 24 VDC operation with high current-driving capacity and fast response times, ensuring effective interaction with the field.
Thanks to its modular design and full compatibility with ABB’s AC500 system family, the DO561 can be easily integrated into both centralized and distributed automation architectures. The module also includes built-in short-circuit protection and diagnostic feedback, helping reduce downtime and improve system reliability.
