S800 I/O Signal Processing and Diagnostics

The AO810V2 uses eight analog output channels to generate 0-20 mA or 4-20 mA signals. Each channel provides a unipolar current output for direct connection to compatible field devices.

The module reads back serial data from the D/A converters and verifies the returned data. Therefore, communication faults between the module logic and D/A conversion circuitry can be detected during operation.

In addition, the module performs cyclic self-diagnostics. It supervises the process power supply and reports insufficient supply voltage to the output circuitry as a channel error.

Channel diagnostics also detect output-current faults on active channels. Specifically, the module reports an error when the measured output current falls below the configured output value while that output value exceeds 1 mA.

The 14 bit resolution supports discrete analog signal conversion, while the specified update cycle remains at or below 2 ms. Furthermore, the 600 meter maximum field cable length provides the stated installation limit for field signal wiring.

Frequently Asked Questions (FAQ)

Q: How many analog output channels does the AO810V2 provide?
A: The AO810V2 provides 8 unipolar analog output channels.

Q: Which output current ranges does the module support?
A: The module supports 0-20 mA and 4-20 mA output signals.

Q: What electrical current does the module draw from its supplies?
A: The module consumes a maximum of 70 mA from the +5 V Modulebus supply and 245 mA from the +24 V external supply.

Field Installation Guidelines

1. Install the AO810V2 according to the applicable ABB S800 I/O hardware installation requirements.
2. Verify the module identity and terminal-unit configuration before connecting field wiring.
3. Use field cables suitable for analog current transmission and keep signal wiring separated from high-voltage and high-current conductors.
4. Maintain the specified maximum field cable length of 600 meters.
5. Connect the 0-20 mA or 4-20 mA circuits according to the configured channel function and field-device requirements.
6. Apply the specified grounding and shielding practice for the installation environment. Avoid unintended shield connections that can introduce ground-current paths.
7. Verify the +5 V Modulebus and +24 V external supply connections before commissioning.
8. After energization, check module and channel diagnostics. In particular, investigate channel errors associated with insufficient process supply or output-current deviation.
9. Confirm the analog output value at the field device before placing the associated control loop into service.
