Features:
- Provides the passive mounting and connection base for a supported Series 8 C300 controller.
- Carries FTE address selection, two FTE ports, and two I/O Link connections.
- Includes the private redundancy and optional memory-backup connection points.
Honeywell 8C-TCNTA1 51307125-175 separates cabinet wiring from the replaceable controller module by locating the external connections on the IOTA.
The FTE paths handle controller networking, while the two I/O Links connect the controller to Series 8 I/O hardware.
A second IOTA and the specified redundancy cable create the private controller-pair path without changing the field I/O termination layout.
The Honeywell 8C-TCNTA1 51307125-175 C300 Controller I/O Termination Assembly is listed as Active / Available from OEM; Apter Power can assist with exact-model documentation and matching.

Network identity and controller access
- Address switches: The FTE address is selected on the IOTA.
- Network ports: Two FTE connectors provide the controller network paths.
- Controller mount: The processor module plugs directly onto the IOTA.
- Power transfer: The IOTA passes Series 8 supply power into the controller.
Two controller-to-I/O paths
- Link count: Two I/O Link connectors are fitted.
- Per-link limit: Each link supports as many as forty I/O units.
- Combined limit: The documented C300 controller total is eighty I/O units.
- Signal role: The links carry controller communication to Series 8 I/O modules.
Matched hardware for controller redundancy
- IOTA quantity: A redundant arrangement uses two IOTAs.
- Controller quantity: One C300 controller is fitted to each IOTA.
- Pair cable: 51305980-836 connects the private redundancy path.
- Shared role: The paired bases keep network and I/O interfaces available to both controllers.
Optional retained-memory connection
- Backup port: The IOTA includes the C300 memory-backup connection.
- Charger module: The documented backup uses the Series 8 RAM charger assembly.
- Retention role: Backup power preserves controller RAM after the main source is removed.
- Separation: The passive IOTA carries the connection while the controller contains the retained memory.
