- Four individually isolated bipolar analog output channels
- Configurable current and voltage ranges from -20 mA to +20 mA and -10 V to +10 V
- Compatible with TU810, TU812, TU814, TU830 and TU833 MTUs
ABB AO820 3BSE008546R1 provides four independently configurable analog output channels for S800 I/O installations.
Each channel must be configured in software and connected to the correct current or voltage terminals for the receiving field device.
Before commissioning, verify polarity, engineering scaling, output load, process-voltage supervision, open-circuit diagnostics and the configured OSP state.
Availability, condition, price, and shipping time for AO820 3BSE008546R1 are confirmed during quotation.

- Configure each channel in software for the required current or voltage range
- Match polarity and engineering scaling to the receiving device
- Do not infer channel mode from field wiring alone
- Use a compatible TU810, TU812, TU814, TU830 or TU833 MTU
- Keep channel conductors and references on their assigned isolated terminals
- Check current-loop resistance or voltage-input impedance before commissioning
- Use output readback to compare commanded and delivered values
- Investigate open-circuit current alarms and low process voltage before replacing the module
- Verify the configured OSP state for controller or communication faults
- Bipolar setpoint output to industrial drives
- Current-loop command to valves and positioners
- Isolated voltage or current reference generation in S800 I/O stations
