More Information

Overview Manuals FTE Connections I/O Link Paths Redundant Base Backup Interface

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.

All prices are shown in USD.

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.
Description
Honeywell 8C-TCNTA1 51307125-175 is the conformally coated I/O Termination Assembly for the Series 8 C300 controller. It forms the passive base beneath the controller module and concentrates the network, I/O Link, power, and auxiliary connections at the cabinet wiring boundary.

FTE address switches and two FTE connectors on 8C-TCNTA1 51307125-175 establish the controller network position, while two I/O Link connectors route controller communication to the installed Series 8 I/O units. The controller module receives operating power through the IOTA rather than through a separate front connector.

The private redundancy connection on 8C-TCNTA1 51307125-175 is used with a second controller/IOTA assembly and cable 51305980-836. The same base also provides the connection used by the optional C300 memory-backup hardware.

Because 8C-TCNTA1 51307125-175 contains passive controller-interface devices, its role is termination and interconnection rather than control execution. The exact IOTA identity must therefore be matched to the supported C300 controller before the processor is fitted.
