The CC-TCNT01 functions as the physical interface between the C300 Controller module and the field wiring infrastructure within Experion PKS Series C systems. Specifically, this termination assembly carries every critical connection the controller requires for operation. These connections include Fault Tolerant Ethernet (FTE) links, IO Link communications, controller redundancy cabling, battery backup connections and time source synchronization terminals. Furthermore, the IOTA delivers regulated 24VDC power directly to the controller module, eliminating the need for separate power feed wiring to the controller slot. The unit supports hot-swap maintenance, allowing technicians to replace the C300 controller without disturbing field terminations.
The CC-TCNT01 serves as a passive backplane interface that routes signals and power between the controller and the cabinet infrastructure. Its design prioritizes signal integrity and maintenance accessibility.
The assembly consolidates all controller cable terminations onto a single mounting platform. First, it provides dedicated connection points for FTE network cables, supporting the fault-tolerant topology required for high-availability DCS architectures. Next, IO Link terminals carry communication between the controller and distributed I/O modules. Additionally, the IOTA includes separate terminals for redundancy cabling, battery connections and time source synchronization. This centralized termination approach reduces wiring complexity inside the cabinet.
The IOTA distributes 24VDC to the controller module with a supply rating of 0.311A. This current capacity supports the C300 controller's operational requirements without external power conditioning at the slot level. Moreover, the power distribution design isolates the controller from cabinet-level power fluctuations through the IOTA's internal routing.
The assembly occupies a standard C300 slot position and mounts directly to the Series C carrier. It supports an operating temperature range of -40°C to +70°C and a storage range of -40°C to +85°C. Relative humidity tolerance reaches 95% without condensation. The terminal blocks accept wire sizes from AWG 28 to 12 (0.08 to 3.3 mm²), accommodating common field wiring gauges.
The CC-TCNT01 is engineered for continuous operation in industrial control cabinets. The terminal blocks use screw-type connections that maintain mechanical stability under vibration. Furthermore, the assembly supports hot-swap replacement of the controller module, which minimizes downtime during maintenance windows. The IOTA does not generate significant heat, as it operates as a passive termination and power distribution platform. Its form factor aligns with the Series C carrier rail system, ensuring proper alignment with the controller backplane connector.
Proper installation begins with verifying that the mounting location matches the C300 controller slot assignment in the cabinet layout. First, secure the CC-TCNT01 to the Series C carrier using the designated mounting fasteners. Next, route the FTE cables to the designated FTE termination points, observing the A and B link separation required for fault-tolerant operation. Connect the IO Link, redundancy, battery and time source cables to their respective terminals.
When wiring field terminations, confirm that wire stripping lengths match the terminal block specifications and that screw terminals are tightened to the recommended torque. Meanwhile, verify the 24VDC power source polarity before energizing the assembly. After power is applied, insert the C300 controller module into the IOTA slot and confirm that the module seats fully. Finally, verify communication status through the controller diagnostics before placing the system into service.

Q1: What is the primary function of the CC-TCNT01 in a C300 system?
A1: The CC-TCNT01 provides the physical termination platform for all C300 controller connections. It routes FTE, IO Link, redundancy, battery and time source signals while distributing 24VDC power to the controller.
Q2: Can the C300 controller be replaced without removing field wiring from the IOTA?
A2: Yes. The CC-TCNT01 supports hot-swap controller replacement. Technicians can remove the controller module while leaving all field terminations secured on the IOTA.
Q3: What is the supply rating of the CC-TCNT01?
A3: The assembly distributes power at 0.311A at 24VDC to the controller module.
Q4: What wire gauge range do the terminal blocks accept?
A4: The screw terminals accept conductors from AWG 28 to 12 (0.08 to 3.3 mm²).
Q5: Does the CC-TCNT01 require separate power wiring to the controller?
A5: No. The IOTA handles 24VDC distribution internally through the backplane interface. Only the main power feed to the IOTA itself requires wiring.
