Product Overview

The CC-TCNT01 is the dedicated IOTA termination base board exclusively matched with Honeywell CC-PCNT01 C300 core controller, a mandatory bottom carrier component of the Experion PKS distributed control system widely deployed in petrochemical, power generation, oil & gas, chemical and pharmaceutical process industries.

It acts as the central wiring and communication hub between the C300 main CPU and the entire DCS rack subsystem. It distributes 24VDC working power to the controller, integrates all physical cable termination points including redundant FTE control network, I/O expansion bus, controller hot standby synchronization line, memory backup battery and system clock signal wiring.
