ABB Industrial Control Communication Characteristics

The CI810B uses two AF100 twisted-pair modems to provide the physical communication interface for the AF100 fieldbus. Therefore, installation should maintain proper separation between communication wiring and high-energy power conductors.

The module operates from a 24 VDC supply and provides 1500 VDC isolation. This isolation specification defines the stated electrical isolation capability between applicable circuits; it does not replace the system grounding requirements.

The CI810B uses snap-on mounting for a 35 mm DIN rail. Consequently, the mounting rail should remain mechanically secure and electrically bonded according to the control cabinet design.

Frequently Asked Questions (FAQ)

Q: What fieldbus does the CI810B 3BSE020520R1 support?

Q: What mounting method does the CI810B use?
A: The module mounts on a 35 mm DIN rail using a snap-on mounting arrangement.

Field Installation Guidelines

• Verify that the cabinet provides a secure 35 mm DIN rail before mounting the module.
• Confirm the 24 VDC supply polarity and voltage before energizing the interface.
• Route AF100 twisted-pair communication wiring separately from high-voltage and high-current conductors.
• Use the specified connectors and terminal blocks supplied for the module configuration.
• Install the TB807 Modulebus Terminator where required by the applicable ABB system architecture.
• Maintain shield and grounding practices specified by the ABB installation documentation for the associated fieldbus network.
• Keep communication cable routing free from unnecessary loops and excessive proximity to switching power devices.
• Confirm all field wiring terminations before applying system power.
