- Honeywell 8C-TCNT01 51307032-175 C300 Series 8 Control Network Module
SKU: 8C-TCNT01Â 8U-TCNT01Â 51307032-175
Honeywell 8C-TCNT01 51307032-175 C300 Series 8 Control Network Module
The Honeywell 8C-TCNT01 (51307032-175) is a high-performance Series 8 Control Network Interface for Experion PKS systems. It provides redundant FTE connectivity and a hot-swappable design to ensure seamless data exchange between C300 controllers and distributed I/O.
Product Overview
The Honeywell 8C-TCNT01, designated by part number 51307032-175 and assembly number 8U-TCNT01, serves as the primary communications bridge for the Experion PKS C300 control environment. This module facilitates high-speed data exchange between the C300 controller and the wider I/O network, ensuring that process variables reach the control logic with sub-millisecond precision. By utilizing the advanced Series 8 hardware platform, this interface provides a deterministic path for critical automation data in demanding industrial settings.
Functional Performance
This module actively manages the physical and data link layers of the Honeywell Control Network. It translates complex field data into actionable information for the controller while maintaining a Fault Tolerant Ethernet (FTE) connection. Furthermore, the 8C-TCNT01 employs redundant circuitry to prevent communication blackouts; if the primary link encounters an error, the module shifts traffic to the backup path instantaneously. The vertical orientation of the module also enhances passive cooling, which extends the operational life of the internal electronics even in high-density cabinet layouts.
