Description
ABB DO814: Product Overview
The ABB DO814 is a 16-channel digital output module from the AC500 Series, designed for integration with ABB’s AC500 programmable logic controllers (PLCs). As a high-density I/O component of the AC500 system, it bridges PLC logic outputs with field devices requiring discrete switching signals (e.g., relays, solenoid valves, indicator lights).
Engineered for industrial automation, the DO814 features photoelectric isolation (250V AC) to shield 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 multi-point discrete control—such as machine automation, process control, and building management systems—where reducing module count and wiring complexity is critical.

Core Features & Customer Value
-
16-Channel High-Density Output: Supports simultaneous control of 16 field devices (e.g., 16 solenoid valves or relay coils) in a single module—reducing cabinet space and wiring time compared to 8-channel alternatives.
-
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 Total Current Capacity: Delivers 0.5A per channel (8A total), sufficient to drive multiple small relays, contactors, or LED indicators without external amplification.
-
Seamless AC500 Integration: Plugs directly into ABB’s AC500 I/O racks and communicates via the PLC’s internal bus—simplifying configuration and reducing setup time for AC500 users.

Typical Applications
The ABB DO814 is widely used in industrial automation for multi-point discrete control:
-
Machine Automation: Controls pneumatic/hydraulic valves, motor starters, and safety interlocks in packaging machines, CNC routers, and conveyor systems (e.g., 16-cylinder pneumatic grippers).
-
Process Control: Drives solenoid valves for liquid/gas flow control in water treatment, chemical dosing, and food processing (e.g., 16-channel valve manifold for batch mixing).
-
Building Automation: Switches lighting circuits, HVAC dampers, and access control relays in smart factories or commercial buildings (e.g., 16-zone lighting control).
-
OEM Equipment: Embedded in original equipment manufacturer (OEM) machines for plug-and-play discrete control (e.g., medical device assembly stations with 16 actuators).
