- Exact 621-1100RC appears in a Honeywell-authored guide.
- Its catalog role is 115 Vac/dc 8-point digital input module.
- The receiving LC621 I/O Controller must be verified on site.
The Honeywell manufacturer selection guide provides a direct exact-model reference for 621-1100RC. It identifies the part as a 115 Vac/dc 8-point digital input module in the LC621 I/O Controller. This is strong evidence for the part's basic identity but not for every installation limit or present stock condition. The guide does not supply terminal wiring, isolation, or package dimensions. Do not import terminal ratings, dimensions, accessories or revision compatibility from neighboring product codes. Use the guide together with readable labels and the original project documentation when selecting a replacement.
At the order stage, compare a photograph of the offered unit with the installed full part number, suffix and revision. Check the receiving rack, original cable or terminal arrangement, factory options, electrical service and the approved site drawings. Retain photographs and diagnostic records before removal. Follow local isolation and handling procedures. After a verified replacement, check diagnostics and every affected I/O, communication or supply path under the commissioning plan. Final packed size and weight must be measured from the actual consignment.
The 621-1100RC Honeywell 115 Vac/dc 8-point digital input module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell 621-1100RC official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
The exact 621-1100RC part number appears in Honeywell's model selection table as a 115 Vac/dc 8-point digital input module. The entry places it in the LC621 I/O Controller. That identity must still be checked against the supplied nameplate and full revision. A nearby catalog number or a shortened suffix is not automatically an approved substitute.
Before fitting the part, compare the receiving rack, installed position, connected equipment, cable or terminal map and approved drawings. The guide does not supply terminal wiring, isolation, or package dimensions. Record the original configuration and obtain written clarification if the offered assembly differs in revision or factory option. Installation decisions must follow the actual project documentation.
The reviewed Honeywell guide supports only the exact identity and catalog function described here. It does not certify stocked-unit condition, final shipping dimensions, packed weight or every electrical and mechanical limit. Stronger claims need an exact technical manual, readable nameplate or written confirmation against the physical assembly.
