Honeywell 8C-TCNTA1 Series 8 C300 Controller I/O Termination Assembly

Product Description

Configured for controller termination, network connection, and physical interface functions in the Honeywell Series 8 C300 control system, the Honeywell 8C-TCNTA1 (8C-TCNTA1 I/O Termination Assembly) provides the termination hardware for supported C300 controller modules. It is a coated IOTA and does not contain the C300 controller processor. The assembly supports controller connection, FTE interface, I/O Link connections, and controller redundancy arrangements.

Hardware Specifications

Honeywell specifies the 8C-TCNTA1 as the common IOTA for the supported Series 8 C300 controller configurations. The 8C-PCNT05 uses the same IOTA as the 8C-PCNT03. (霍尼韦尔)

Process Control and DCS Interface Characteristics

The 8C-TCNTA1 provides the physical termination and connection interface associated with the C300 controller. The assembly includes FTE connectors, FTE address switches, and I/O Link connections. The C300 controller provides the control execution environment, while the IOTA provides the corresponding physical connection hardware. 

For redundant C300 operation, Honeywell specifies two controller/IOTA assemblies together with redundancy cable 51305980-836. The IOTA therefore forms part of the physical redundancy connection arrangement rather than executing the control strategy itself. 

The Series 8 C300 architecture also supports communication with other C300 controllers and communication modules such as FOUNDATION Fieldbus and Profibus through the C300 control environment. These communication functions belong to the controller and associated communication architecture, not to the passive IOTA itself. 

Frequently Asked Questions

Q: Is the 8C-TCNTA1 a C300 processor module?

A: No. The 8C-TCNTA1 is the coated C300 Controller I/O Termination Assembly. The C300 processor is provided by a separate controller module such as 8C-PCNT03 or 8C-PCNT05. (霍尼韦尔)

Q: Which C300 controllers use the 8C-TCNTA1 IOTA?

A: Honeywell specifies the 8C-TCNTA1 for the 8C-PCNT03 and 8C-PCNT05 Series 8 C300 controller configurations. (霍尼韦尔)

Q: How is controller redundancy implemented with the 8C-TCNTA1?

A: Honeywell specifies two controller/IOTA assemblies and redundancy cable 51305980-836 for the redundant C300 controller arrangement. 

Field Installation Guidelines

Mount the 8C-TCNTA1 according to the Series 8 C300 hardware installation requirements. Verify the mechanical seating between the controller and IOTA before energizing the assembly.

Confirm the FTE address switch settings against the configured controller addressing. Route FTE and I/O Link cabling separately from high-current power conductors where the installation permits.

For redundant configurations, install the two controller/IOTA assemblies and verify the specified redundancy cable connection before commissioning. Confirm both I/O Link paths and network connections during system checkout.

Use the specified 24 V supply path provided by the Series 8 power system. Do not assign independent power-consumption values to the IOTA without the applicable Honeywell hardware documentation.
