Description
ABB DO880
ABB DO880: Product Overview
The ABB DO880 is an 8-channel digital output module from the AC500 Series, designed for integration with ABB’s AC500 programmable logic controllers (PLCs). As a core component of the AC500 I/O system, it bridges the gap between PLC logic outputs and field devices requiring discrete switching signals (e.g., relays, solenoid valves, indicator lights).
Engineered for industrial automation, the DO880 features photoelectric isolation (250V AC) to protect the PLC from electromagnetic interference (EMI) generated by high-current field devices. Its compact, modular design aligns with ABB’s AC500 form factor, enabling seamless installation in control cabinets or distributed I/O stations. The module is ideal for applications demanding reliable, multi-point discrete control—such as machine automation, process control, and building management systems.

Core Features & Customer Value
-
8-Channel Independent Output: Supports simultaneous control of 8 field devices (e.g., 8 solenoid valves or relay coils), reducing the need for multiple modules in multi-point applications.
-
Photoelectric Isolation: Eliminates EMI-induced false signals by isolating field circuits from the PLC, ensuring reliable operation in electrically noisy environments (e.g., steel mills, motor control centers).
-
Configurable Sink/Source Mode: A DIP switch on the module allows switching between sink (current sinking, field device connected to +24VDC) or source (current sourcing, field device connected to 0VDC) output modes—compatible with diverse field device wiring.
-
High Current Density: Each channel delivers 0.5A (total 4A), sufficient to drive small relays, contactors, or LED indicators without external amplification.
-
Seamless AC500 Integration: Designed for ABB’s AC500 PLC system, the DO880 plugs directly into AC500 I/O racks and communicates via the PLC’s internal bus—simplifying configuration and reducing wiring time.

Typical Applications
The ABB DO880 is widely used in industrial automation for discrete control:
-
Machine Automation: Controls pneumatic/hydraulic valves, motor starters, and safety interlocks in packaging machines, CNC routers, and conveyor systems.
-
Process Control: Drives solenoid valves for liquid/gas flow control in water treatment, chemical dosing, and food processing.
-
Building Automation: Switches lighting circuits, HVAC dampers, and access control relays in smart factories or commercial buildings.
-
OEM Equipment: Embedded in original equipment manufacturer (OEM) machines for plug-and-play discrete control (e.g., medical device assembly stations).
