      Information

      Overview Manuals Industrial Functions and Application Scenarios

      Features:

      • The standard length is 6 feet (approximately 1.8 meters)
      • The cable is assembled based on high-quality 6-core 24 AWG gauge Belden 9536 wire
      • One end of the cable is equipped with a universal 9-pin D-type (DB9) female/male connector (for connecting to a physical serial port of a PC or engineering station or a USB to serial adapter)
      This type of Trusted Communications Cable is designed to connect an Engineering Workstation (EWS) or PC to the front panel RS232 diagnostics port on either the Trusted TMR Processor T8110 or Trusted Communications Interface T8151. The cable assembly consists of a 6-core Belden 9536 cable fitted with a 9-way ‘D’ type connector at one end and a 6-way DIN connector at the other.

      In addition to routine maintenance and diagnostics, this cable can also be used for point-to-point remote extension interconnects between critical controllers and fiber optic transceiver units (T8314) or extension processors (T8310). Its robust external shielding design provides excellent shock resistance (compliant with MIL-STD-810F military standards) and a wide operating temperature range (-40°C to +70°C), ensuring that signal integrity and the system's SIL 3 safety level are not compromised in high-risk, high-EMI environments such as petrochemical and critical process control.

      The TC-304-01 ICS Triplex Communications Cable may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      ICS Triplex TC-304-01 Communications Cable Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      The primary function of the TC-304-01 communication cable is to establish a low-level hardware-level serial diagnostic channel independent of the main control network:
       
      1.Direct Diagnostic Interface: Used to connect the Engineer Workstation (EWS) to the front panel RS-232 diagnostic port of the Trusted TMR Processor Module (T8110) or Trusted Communication Interface Module (T8151).
       
      2.Command Line Interface (CLI): Through this dedicated channel, field technicians can use standard terminal programs to directly invoke the controller's command-line diagnostic protocol at 19200 baud rate, read the highest-level task list, firmware version, channel chassis configuration, and perform advanced troubleshooting.
       
      3.Safety Switch Insulation Immunity: The low-level RS-232 hardware diagnostic data stream is completely unaffected by the physical state of the processor's front panel push-button switches. Even if the buttons are locked, safe read-only diagnostics can be performed, fully complying with the requirements of the SIL 3 functional safety specification regarding prevention of misoperation and safety assessment guidelines.

      Technical notes

      The Rockwell Automation ICS Triplex TC-304-01 is a serial maintenance/diagnostic cable designed specifically for Trusted 8000 Series Triple Modular Redundancy (TMR) safety systems. This cable (typically 6 feet/1.8 meters long) is primarily used to connect an Engineering Station (EWS) or a PC running a terminal program to the front panel diagnostic serial port of the main processor or communication interface module. It runs a command-line diagnostic protocol at 19200 baud, enabling efficient acquisition of system logs, fault diagnosis, and uploading and downloading of the system.ini configuration file.
      PRODUCT & ORDER FAQS

      Questions buyers ask about TC-304-01

      • What is the principal functional purpose of the TC-304-01 in Trusted industrial control implementations?

        The TC-304-01 is a maintenance and communications cable engineered to facilitate robust diagnostic connectivity between an Engineering Workstation (EWS) or PC and the RS-232 diagnostics port of ICS Triplex Trusted controllers such as the T8110 processor or T8151 communications interface.

      • How does TC-304-01 ensure signal integrity during diagnostic interfacing in safety-critical environments?

        The TC-304-01 employs a shielded twisted-pair design with foil and braid shielding that mitigates electromagnetic interference (EMI), preserving data integrity during real-time communication and troubleshooting procedures.

      • What specific connector configurations are integrated into the TC-304-01 assembly?

        The TC-304-01 assembly includes a 9-way ‘D’ type (DB9) connector on one end and a 6-way DIN connector on the other, enabling standardized interfacing with ICS Triplex controller diagnostic ports.

      • Which electrical and physical characteristics define the TC-304-01 for reliable installation?

        The TC-304-01 specification includes 24 AWG conductor gauge, an impedance of 100 ohms, and shielding optimized for high-quality signal transmission, traits that support consistent performance under industrial conditions.

      • How is the TC-304-01 utilized in support of system diagnostics and fault triage within a Trusted TMR system?

        Engineers use the TC-304-01 to establish a direct communications link to the front panel RS-232 diagnostics interface, enabling diagnostic commands, error retrieval, and troubleshooting workflows on Trusted TMR processors and communications modules.

      • What certifications or industrial quality assurances are typically associated with the TC-304-01 cable?

        Although specific certifications may vary by distributor, TC-304-01 assemblies are generally supplied as genuine ICS Triplex components with compliance documentation and manufacturer traceability that ensure conformity with industrial automation standards.

      • Why is understanding the TC-304-01 communication role essential before integration into a Trusted safety-instrumented architecture?

        Because the TC-304-01 mediates diagnostic communication to Trusted processors and interfaces, understanding its electrical, mechanical, and protocol support characteristics is critical to planning maintenance strategies and ensuring system diagnostic access without disrupting redundant TMR operations.
