System Role
- Collects field 24V status and contact signals as part of Honeywell Series 8 I/O nodes.
- Supports high-speed event capture and control polling with normal or fast scan behavior suitable for control-loop visibility.
- Designed for IOTA-based expansion frames and process-control architectures using Series 8 controllers.
Compatibility
Mechanical and electrical compatibility
- Non-redundant 9-inch IOTA slot and 24V digital input electrical interface as defined in the Series 8 table.
- Supports module hot swap / hot insert workflows where frame configuration permits powered replacement.
- I/O behavior aligns with channel counts and scan options listed for the TDILA1 family.
Model family relation
- Uncoated equivalent in series: 8U-TDILA1.
- Redundant 12-inch alternative series (different size and redundancy concept): TDILB1 family.
- Related acquisition modules in official function matrix include 8C-PDILA1, 8C-PDIPA1, 8C-PDISA1, and 8C-PDILA1 context entries.
Applications
- Machine and process-control plants requiring compact 32-point discrete inputs.
- Discrete safety interlock and status signal collection in 24V environments.
- Backbone expansions where hot replacement policy and compact IOTA density are valued.
FAQ
Is 8C-TDILA1 a 9-inch non-redundant module?
Yes. The module is listed in the Series 8 list as a 9-inch IOTA digital input variant and is the coated non-redundant version.
How many channels are available and what are the scan values?
It provides 32 input points with 20 ms normal scan and 5 ms fast scan capabilities.
Can the module be removed or inserted while powered?
Yes. The specification supports module insertion and removal under power.
What is the difference from uncoated or redundant variants?
8C-TDILA1 is coated. The uncoated counterpart is 8U-TDILA1. Redundant variants in the family are sized differently and are represented by TDILB1 references, so they are not direct replacements when redundancy or frame geometry is required.
What is the on/off signal characteristic and filter behavior?
Input operation references the 24V digital input definition for the module class, with filter delay indicated as 5 ms ±20% in the module characteristics section.
Are there official discontinuation, end-of-life, or direct replacement notices?
No confirmed end-of-life or stop-date notice for 8C-TDILA1 was found in the retrieved official Series 8 specification source. If lifecycle decisions are needed for procurement, request an official lifecycle confirmation and approved replacement model before stocking.
