Description
Product Description
The Honeywell CC-TCNT01 (51308307-175) is a Controller Input/Output Termination Assembly (IOTA) designed for the Experion PKS C300 distributed control system. It provides the mounting and connection interface for a compatible C300 controller and terminates essential system connections, including Fault Tolerant Ethernet (FTE), I/O Link, redundancy, battery, and time-source cabling. The assembly also distributes 24 VDC power to the controller module. It is a controller interface assembly rather than a standalone CPU or field I/O module, making correct hardware matching essential during maintenance and replacement.
