Product Precautions
Honeywell 8C-TDIL51 is the coated non-redundant Cx-TDIL51 termination assembly that connects 32 high-level 24 Vdc field states to the matched digital-input module.
- 32 digital inputs
- 24 Vdc high-level signals
- Non-redundant coated IOTA
- 51306969-175 maintenance identity
The IOTA terminates powered contacts or status signals and routes them to the associated digital-input IOM. Field power, commons, terminal plugs and input state interpretation remain part of the installed design.
Important Notice: Use the complete 8C-TDIL51 51306969-175 identity; the redundant Cx-TDIL61 and the CC-TDIL family have different hardware selections.
