Honeywell TK-CCR013 Redundant Net Interface Module

Honeywell TK-CCR013 Redundant Net Interface Module

The Honeywell TK-CCR013 is a redundant network interface module designed to provide fault-tolerant Ethernet communications within Honeywell and Triconex-based control and safety systems. The module supports dual network paths with automatic failover, enabling continuous communication between controllers, workstations, and system components while maintaining network availability during cable or port failures.

Technical Specifications

Redundant Network Architecture

The TK-CCR013 provides two independent Ethernet communication paths to improve network availability in critical control environments. When one communication path becomes unavailable, the module automatically transfers network traffic to the alternate path without requiring manual intervention.

This redundancy mechanism helps maintain communication continuity between controllers, engineering stations, operator workstations, and other networked devices connected to the control infrastructure.

Ethernet Communication Functions

The module supports 100Base-TX Ethernet communication over standard Cat5e or Cat6 cabling. With a data transfer rate of 100 Mbps, the interface is suitable for exchanging real-time process data, diagnostics, configuration information, and supervisory control traffic.

Supported protocols include Modbus TCP/IP, TriStation, and TSAA, enabling communication with compatible control, monitoring, and engineering platforms.

Environmental Protection

The TK prefix identifies the conformally coated version of the module. The protective coating helps shield electronic components from moisture, airborne contaminants, and corrosive atmospheres commonly encountered in industrial environments.

This construction is particularly useful in facilities where environmental conditions may reduce the service life of uncoated electronic assemblies.

Integration in Safety Systems

The TK-CCR013 is intended for use in fault-tolerant automation and safety applications where high network availability is required. The module supports deployment within redundant architectures and is specified as SIL 3 capable for applications designed in accordance with IEC 61508 requirements.

Support for hazardous-area approvals including ATEX Zone 2, IECEx, and FM Class I Division 2 allows installation in qualified industrial locations when used according to applicable certification requirements.

Electrical Characteristics

The module operates from a nominal 24 VDC supply and consumes approximately 5 W to 7 W depending on operating conditions and network activity. Galvanic isolation between the network circuitry and internal electronics is specified at 1500 VAC, helping reduce the effects of electrical disturbances between connected systems.

Frequently Asked Questions

Q: What is the purpose of the dual Ethernet ports on the TK-CCR013?

A: The two 100Base-TX ports provide redundant network connectivity. If one communication path fails, traffic can automatically continue over the alternate path.

Q: Does the TK-CCR013 support standard Ethernet cabling?

A: Yes. The module supports Cat5e or Cat6 UTP/STP Ethernet cables and operates at 100 Mbps.

Q: What does the TK prefix indicate?

A: The TK designation identifies the conformally coated version of the module, providing additional protection against moisture, dust, and corrosive contaminants.
