Features:
- Honeywell's manufacturer table names TK-IOLI01 as an I/O Link Interface.
- The same OEM table separately lists TC-IOLI01, so model identity matters.
- The table does not assert generic IO-Link device-port functionality or exact environmental ratings.
Page 11 of Honeywell's January 2023 System HINTS newsletter lists TK-IOLI01 with the description I/O Link Interface. TC-IOLI01 appears as a separate entry with the same broad function. The document establishes model-level role but not specific field-protocol features, port count, connector arrangement, electrical load or environmental limits. In particular, the phrase I/O Link Interface should not be converted into a claim that the card implements the unrelated generic IO-Link sensor protocol. A correct replacement selection requires the actual Honeywell system manual, bill of materials and physical label for the installed execution.
Before work on an I/O-link interface, identify the controller, both link endpoints, adjacent I/O hardware, network or cable routing, active alarms and the current application backup. Confirm the TK-IOLI01 and 51403427-275 markings with a manufacturer parts record; the additional number is not cross-referenced by the reviewed newsletter. Qualified staff should use release-specific isolation and replacement procedures. After an approved exchange, verify module recognition, link diagnostics, controller communication and all affected I/O paths under the site's test plan. The newsletter is not a current lifecycle notice and does not authorize hot swapping or universal interchangeability with TC-IOLI01.
The TK-IOLI01 51403427-275 Honeywell I/O Link Interface may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell TK-IOLI01 51403427-275 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.
Honeywell's page 11 table lists TK-IOLI01 as an I/O Link Interface and separately names TC-IOLI01. It does not map the site's additional 51403427-275 number or establish interchangeability between the two models. Check the allocated unit's physical marking, revision and system bill of materials before a purchase or maintenance decision.
The manufacturer's table gives a high-level I/O Link Interface description only. It does not define a generic IO-Link sensor-port standard, channel count, cable pinout or network performance for TK-IOLI01. Do not copy such details from a similarly named product. Use the release-specific Honeywell controller and I/O documentation to confirm the installed link topology and permitted connections.
Record controller and I/O endpoints, existing link alarms and configuration before an authorized module exchange. Follow the site's isolation and Honeywell service instructions for the installed release. After fitting the approved exact part, verify recognition, communication health and each affected I/O path. The reviewed newsletter does not supply environmental ratings, current lifecycle status or permission to replace the module under power.
