ABB S800 I/O Backplane and I/O Density Scaling

The DI818 integrates with the ABB S800 I/O architecture through the module backplane communication interface. Therefore, the module supports high-density digital input deployment with 32 channels arranged into two electrically isolated groups of 16 channels.

The isolated channel grouping reduces signal interaction between field circuits and the control system. Additionally, the module termination units TU818, TU819, and TU830 provide the required field wiring interface for cabinet installation and signal distribution.

Frequently Asked Questions

Q: How are the DI818 input channels electrically organized?
A: The DI818 contains 32 digital input channels divided into two isolated groups of 16 channels. Each group operates as an independent field signal section.

Q: Which termination units support the DI818 module?
A: The DI818 is designed for use with ABB TU818, TU819, and TU830 Module Termination Units for field connection.

Q: Can the DI818 be installed in systems requiring channel isolation?
A: Yes. The module provides electrical isolation between the two groups of 16 input channels, supporting separated field signal wiring configurations.

Field Installation Guidelines

• Install the DI818 module on the compatible ABB S800 I/O carrier according to ABB system installation procedures.
• Verify that the selected Module Termination Unit matches the field wiring requirements before connection.
• Separate low-level signal cables from high-voltage power wiring to reduce electrical interference.
• Connect field cable shields according to the cabinet grounding design and local electrical standards.
• Confirm the 24 VDC input wiring polarity before applying field power.
• Check module status indicators after installation to verify correct communication and input operation.
