ABB AO02 is a high-performance analog output module developed for ABB Ability™ Symphony® Plus DCS platform and categorized into SD series I/O modules for industrial automation and process control applications. Equipped with 16 group-isolated analog output channels, the module allows independent configuration of each channel for 4-20mA current signal or 1-5VDC voltage signal, perfectly driving industrial actuators such as control valves and frequency converters.

Integrated with a built-in HART 5.4 modem, AO02 supports two-way communication with HART smart instruments. It can retrieve up to 20 secondary variables to realize remote parameter configuration, status monitoring and fault diagnosis, effectively cutting down on-site maintenance costs. Each channel is fitted with an independent 12-bit D/A converter, delivering outstanding signal resolution and linearity. The full-scale accuracy reaches ±0.01%FSR with a response time less than 1ms, meeting strict requirements for precision and stability in process control.

In terms of electrical performance, it provides 1500VAC isolation between channels and between channels and the system bus, which suppresses ground loop interference and electromagnetic disturbance effectively. The current output is protected against short circuit with a maximum current limited to 26mA, and open circuit faults can be detected within 5 seconds. Powered by 24VDC, the module supports field cables up to 600 meters long, suitable for large-scale distributed factory layouts.

With compact structure, DIN rail mounting and hot-swap capability, the module can be replaced during system operation without system shutdown. As a core I/O card for ABB DCS, it has been widely applied in chemical, oil & gas, power, metallurgy and water treatment industries.
