AO810V2 3BSE038415R1 ABB Analog output module AC 800M System 800 A8

AO810V2 3BSE038415R1 ABB Analog output module AC 800M System 800 A8

The ABB AO810V2 is the second-generation 8-channel analog output module in the AC 800M distributed control system, specifically designed for 4-20mA signal output applications in industrial automation. As an upgraded version of the classic AO810, the AO810V2 maintains high compatibility while optimizing diagnostic functions, anti-interference capabilities, and long-term stability. It is suitable for driving field devices such as electric control valves, frequency converters, actuators, and recorders.

Core features

8-channel independent analog output
Output signal: 4-20 mA (default), which can be configured by software as 0-20 mA
Load capacity: Maximum 750 Ω (@24V DC)
Output accuracy: ±0.1% of span (typical value, 25°C)
High-reliability design
Electrical isolation between channels: ≥ 500 V AC
Short-circuit protection: All output channels are equipped with automatic current limiting and recovery functions
Open circuit detection: Optional to enable (through software configuration)

Technical parameters

Process control loop: Electrical valve positioner (I/P converter) for driving pneumatic control valves
Motor speed control system: Sends a 4-20mA speed setting signal to the frequency converter
Boiler and Combustion control: Adjust the opening degree of the fuel valve and the position of the damper
Water treatment plant: Control the stroke of the dosing pump and the dosage of flocculant
Test and calibration bench: Serves as a standard signal source to output precise current values

Installation and Usage instructions
Hardware installation
Insert the AO810V2 into the S800 I/O electronic rack (such as TB840A);
Connect to the CI854A (optical fiber) or CI801 (electrical) communication module via the ModuleBus cable;
Connect the output terminals to the on-site execution equipment using shielded cables.
Software configuration
Create an instance of the AO810V2 device in Control Builder M;
Set for each channel:
Output range (4-20 mA or 0-20 mA
Engineering units (%, Hz, °C, etc.)
Alarm limit values and fault actions (such as output hold/reset to zero during a fault)
Enable the "Open Circuit Detection" function (optional);
Download the configuration to the AC 800M controller.
Debugging and verification
The green LED on the front panel indicates that the module is operating normally.
If a certain channel is short-circuited, the corresponding channel will limit the current and report the fault.
Loop testing can be performed by forcing the output value through Control Builder M.
