The Honeywell TC-CCR014 97321174-A01 is a high-reliability redundant network interface module specially designed for industrial automation systems. Its core positioning is to provide uninterrupted control network communication guarantee for critical industrial scenarios. Adopting a redundant architecture design, it is compatible with mainstream controllers such as the Honeywell C300, while supporting multiple industrial communication protocols and connection media. It not only operates stably in harsh industrial environments with extreme temperatures, vibrations and other conditions, but also prevents system downtime caused by single-point failures through an automatic fault switching mechanism. This module is widely used in industries with stringent system availability requirements, including oil and gas, power generation, and chemical engineering.

Core Technical Specifications

Network & Communication

This module supports dual-port connectivity: Port A features a twisted-pair interface with a DB9 male connector, while Port B offers optional fiber-optic connectivity with SC or ST interfaces, delivering a communication rate of 5 Mbps. The maximum transmission distance is 100 meters for twisted-pair connections and up to 10 kilometers for fiber-optic connections (depending on fiber type). Boasting robust protocol compatibility, it supports multiple commonly used industrial protocols including Modbus TCP/IP, Ethernet/IP, PROFINET and CIP, enabling flexible integration into industrial control systems of different architectures.

Power Supply & Power Consumption

Documentation from different sources indicates that its power supply specifications are tailored for industrial scenarios. It is available in both versions that draw power from the backplane with 5.1V DC (970mA power consumption) and versions that support a wide 24V DC (±10%) voltage range. Some models are equipped with a dual DC input design, featuring reverse polarity protection and internal isolation, with typical power consumption below 5W. This allows the module to adapt to various industrial power supply configurations.

Environmental Adaptability

It offers excellent weather resistance, with an operating temperature range of -40°C to 70°C; some variants can withstand a storage temperature range of -40°C to 85°C. It is suitable for humidity conditions of 0%–95% non-condensing, and provides resistance to 5g vibration (10Hz–2kHz) and 50g shock (11ms). The module complies with industrial safety certification standards such as Class I, Division 2, making it ideal for harsh operating conditions.

Physical Dimensions

Adopting a compact design, its dimensions vary slightly across different configurations. Common specifications include 100mm × 160mm × 25mm or 17.2cm × 14cm × 3.5cm, with a weight of approximately 0.45kg. Its compact form factor facilitates installation in control cabinets and saves mounting space.

Functional Features

Redundancy & Fault-Tolerance Mechanism

This stands as the module core advantage. Its dual-port and redundant architecture supports automatic fault switching with a switching time of less than 10 milliseconds. In the event of a connection failure in either the twisted-pair or fiber-optic link, the system will seamlessly switch to the standby link. This significantly minimizes the risk of network interruption and ensures the continuous transmission of critical data.

Convenient Operation, Maintenance & Monitoring

Certain versions come with a built-in web server, enabling staff to perform parameter configuration and real-time status monitoring remotely via the network. Equipped with LED indicators for power supply, communication, and port activity status, the module allows for quick fault localization. Meanwhile, its integrated diagnostic function provides real-time feedback on system health, helping maintenance personnel identify potential risks proactively.

Broad Compatibility

The module is not only custom-adapted for Honeywell C300 controllers, but also compatible with PLC/DCS platforms of other brands such as ControlLogix. Some models are rated to support reliable communication for up to 99 network nodes and 200 PLCs. This allows flexible integration into existing industrial systems, reducing the costs associated with system upgrades and retrofits.

Application Scenarios

The high reliability of the Honeywell TC-CCR014 makes it suitable for a wide range of critical industrial scenarios.

In the oil and gas sector, it can be used to ensure the stability of communication links between oil and gas extraction equipment and control systems. In the power industry, it is compatible with unit monitoring and dispatching systems in power plants. Within chemical production, it provides stable connectivity for the control units of equipment such as reactors and transfer pumps.

Furthermore, it is also applicable to heating, ventilation, air conditioning (HVAC) and security systems in building automation, as well as production line control networks in manufacturing industries including papermaking, food and beverage. It lays a solid communication foundation for the continuous operation of various industrial systems.
