Why Choose the ABB TA5126-2AO-UI Analogue Output Option Board?
The ABB TA5126-2AO-UI is a compact analogue output option board designed to extend the analogue control capability of compatible ABB AC500-eCo V3 programmable logic controllers. It provides two configurable analogue outputs, identified as O0 and O1, for controlling industrial drives, actuators, valves, instrumentation and other devices requiring variable voltage or current reference signals.
Designed for ABB AC500-eCo V3 PM50xx CPUs, the TA5126-2AO-UI supports both 0–10 V voltage and 0–20 mA current outputs. The two channels provide 12-bit resolution and form a single analogue output group, giving automation engineers a flexible way to generate precise process control signals directly from the PLC.
The TA5126-2AO-UI features galvanic isolation and two yellow LEDs for output status indication. A removable 6-pin spring terminal block with 3.50 mm pitch is included for the analogue output signals and 24 V DC process supply, providing a compact solution for adding analogue control capability to AC500-eCo V3 automation systems.

Precise Analogue Control for AC500-eCo V3 PLCs
Analogue output modules allow PLC systems to generate continuously variable electrical control signals rather than simple on/off outputs. The ABB TA5126-2AO-UI provides two independently configurable channels for sending voltage or current reference signals to compatible industrial equipment, enabling precise control of process variables and machine functions.
The 0–10 V and 0–20 mA output ranges make the TA5126-2AO-UI suitable for applications such as variable speed drive references, proportional valve positioning and analogue instrumentation control. Its 12-bit resolution, galvanic isolation and compact option-board construction make it a practical choice where additional analogue outputs are required without installing a separate external I/O module.
Typical Applications
- Variable speed drive speed reference control.
- Proportional valve and actuator positioning.
- Industrial process control systems.
- Pump, fan and ventilation control.
- HVAC and building automation systems.
- Analogue instrumentation and signal control.
- Packaging and production machinery.
- OEM control panels using ABB AC500-eCo V3 PLCs.
