An ABB Digital Output Module (DOM) is a standard industrial automation module used to provide discrete digital switching outputs from a control system to field devices. These modules receive logic signals from a controller (PLC, DCS or protection controller) and produce scaled output signals (typically 24 V DC) for driving actuators, relays, indicators, contactors or solenoid valves. Digital Output Modules are typically installed in DIN‑rail or rack‑mounted I/O assemblies as part of ABB’s distributed I/O solutions in industrial automation, power generation, process control, and utility control systems.
