Principle of use
Signal conversion and output: The controller (such as AC 800M) sends digital instructions to the AO801 module via Modulebus.
The internal DAC (digital-to-analog converter) of ABB AO801 3BSE020514R1 converts the digital signal into an analog current signal of 0–20 mA or 4–20 mA, which is output to the field device through the MTU (module terminal unit).
Self-diagnosis and protection: ABB AO801 3BSE020514R1 periodically performs self-tests to detect faults such as short circuits and overloads, and indicates the operating/fault status through the status LED (S light). When an abnormality is detected, the OSP (output safety state) function is triggered to switch the output to a preset safety value (such as keeping the last value or returning to zero).
Redundancy and expansion: Supports redundant configuration (requires redundant power supply and communication modules) to ensure high system availability. Each CI801 communication interface can connect up to 7 AO801 modules, which is suitable for large-scale distributed I/O systems.
Functional characteristics
High-precision control: 12-bit resolution combined with an error rate of ±0.1% ensures the accuracy of signal output, which is suitable for process control scenarios with strict accuracy requirements.
Flexible configuration: Programmable output range (0–20 mA or 4–20 mA), support for HART protocol (specific version required), compatible with smart instrument communication.
Reliability and durability: Short-circuit protection design, the output can withstand short-circuit with +24 V power supply or ground (ZP).
Convenient diagnosis and maintenance: The front LED status indicator shows the module operating status (normal/fault) in real time. Support remote monitoring and debugging through Compact Control Builder software to reduce downtime.
Wide compatibility: Seamless integration with ABB 800xA, AC 800M and other systems, and compatible with third-party PLC or DCS systems through GSD files.
