The ABB DI562 is a digital input module designed for use with ABB’s AC500‑eCo / S500‑eCo programmable logic controller (PLC) platform. It serves as part of a distributed I/O system that interfaces field‑level discrete devices such as sensors, switches, and other 24 V DC input sources to a PLC for automation and control tasks. The module supports multiple digital channels, sink/source input operation, and easy integration into PLC racks or bus systems — enabling reliable monitoring of discrete signals in industrial automation environments.
