Product Overview

The Honeywell TC-CCR012 functions as a high-availability communication bridge specifically designed for the Experion PKS C300 controller platform. This 100% Brand New and Original Redundant ControlNet Interface provides the critical dual-link connectivity required to synchronize data between controllers and remote I/O chassis. By utilizing two independent physical ports (Port A and Port B), the TC-CCR012 ensures that a single cable break, connector failure, or port malfunction does not disrupt process visibility or control. It serves as a fundamental component in mission-critical Distributed Control Systems (DCS) where network uptime directly dictates facility safety and production continuity.

Technical Specifications

Engineering Advantages

• Deterministic Failover Logic: The TC-CCR012 incorporates hardware-level failover mechanisms. If the primary communication path encounters a signal loss or packet corruption, the module switches to the redundant port in milliseconds. This deterministic response maintains the strict timing requirements of the ControlNet protocol, preventing controller timeouts.

• Extreme Environmental Hardening: Unlike standard networking equipment, the TC-CCR012 operates reliably across a wide thermal gradient from -40 to +70 deg C. This allows for installation in unconditioned remote instrument enclosures or extreme climate zones without risking network dropouts due to thermal stress.

• Advanced EMI/RFI Shielding: The module utilizes DB9 connectors and supports Shielded Twisted Pair (STP) media to mitigate the effects of electromagnetic interference. This design ensures signal integrity when the bridge operates near high-voltage motor starters, variable frequency drives (VFDs), or heavy industrial switching gear.

• Low Power Footprint: By limiting power dissipation to less than 5 Watts, the module minimizes the heat load within the C300 controller rack. This low thermal output extends the MTBF (Mean Time Between Failures) of the bridge and adjacent modules, reducing long-term maintenance costs.

FAQs

• How does the TC-CCR012 indicate a network fault?

• The module features integrated front-panel LED indicators. These LEDs provide real-time status for the overall network health and specific activity on Port A and Port B. A "Fault" LED immediately signals a loss of redundancy or a configuration mismatch.

• Can I use standard serial cables with the DB9 ports?

• No. While the module uses DB9 connectors, you must use certified ControlNet Shielded Twisted Pair (STP) cabling. Standard serial cables lack the impedance matching and shielding necessary to maintain the 5 Mbps deterministic data rate required by the Experion PKS architecture.

• Does the TC-CCR012 support hot-swapping?

• Yes. In a redundant system configuration, you can replace a faulty TC-CCR012 module while the system is energized. Once the new module is seated, the C300 controller automatically re-establishes the redundant network link without process interruption.

• What is the transmission limit for ControlNet via this bridge?

• The bridge operates at a fixed 5 Mbps rate. The total distance and number of nodes depend on your specific network topology (trunkline/dropline) and the use of repeaters, but the TC-CCR012 ensures the maximum repeatable performance allowed by the ControlNet standard.
