      Overview Manuals Common Applications Product Precautions
      Honeywell 8C-TCNTA1 is a coated Series 8 C300 Controller I/O Termination Assembly (IOTA). It provides the controller mounting, 24 V power, I/O-link and redundancy termination base for a C300 node.
      • Mounts the C300 controller on its Series 8 termination base
      • Accepts either 8C-PCNT03 or 8C-PCNT05 controller hardware
      • Routes controller supply and I/O-link connections
      • Supports the documented redundant-controller cable arrangement

      8C-TCNTA1 installs with a C300 controller, Series 8 power cables, controller-to-IOTA connection hardware and redundancy cable 51305980-836 when a redundant node is configured. It is used in Experion PKS C300 controller cabinets that coordinate Series 8 I/O links and dual FTE uplinks.

      Important Notice: Verify the complete 8C-TCNTA1 marking, the installed 8C-PCNT03 or 8C-PCNT05 controller, cabinet power cabling, I/O-link connections and approved redundancy arrangement before insertion or replacement.

      Read the applicable Honeywell installation instructions before work. Verify 8C-TCNTA1 and the installed Experion PKS C300 configuration.
      1
      Verify the complete 8C-TCNTA1 marking and its assigned C300 controller-IOTA position before work.
      2
      Place the connected process and control strategy in the approved maintenance state.
      3
      Isolate the applicable cabinet supply and controller field energy before disconnecting conductors.
      4
      Record controller position, I/O-link routing, cable identities and redundancy arrangement before removal.
      5
      Use ESD controls and protect the backplane connector, terminal hardware and coated electronics.
      6
      Confirm the installed 8C-PCNT03 or 8C-PCNT05 controller and supported Experion release against the approved project.
      7
      Restore power in a controlled sequence and clear only diagnostics created by the maintenance activity.
      8
      Complete power, I/O-link, FTE and redundancy checks before returning the C300 node to service.

      Technical notes

      Technical notes

      Verify the installed 8C-PCNT03 or 8C-PCNT05 controller, 24 V Series 8 power cables, I/O-link connections and redundancy cable before inserting the controller. After installation, prove power, I/O-link communication and redundant-controller operation before returning the node to service.

      FAQS

      • Which C300 controller models are compatible with Honeywell 8C-TCNTA1?
        Honeywell specifies 8C-TCNTA1 as the Series 8 C300 IOTA for both 8C-PCNT03 and 8C-PCNT05 controllers. Verify the installed controller model and supported Experion release before replacement.
      • How is Honeywell 8C-TCNTA1 powered in a Series 8 cabinet?
        The C300 hardware requires 24 V DC supplied through cables from the Series 8 power system. Confirm the approved cabinet power cable and connector arrangement before energizing the IOTA.
      • What mounting envelope must be allowed for Honeywell 8C-TCNTA1?
        The specified IOTA dimensions are 220 mm high by 120 mm wide. Use those dimensions to verify carrier position, adjacent-module clearance and cable access.
      • Which redundancy cable is used with Honeywell 8C-TCNTA1?
        A redundant C300 arrangement uses two controllers with two IOTAs and Honeywell redundancy cable 51305980-836. Match both controller positions and the cable identity before start-up.
      • Can Honeywell 8C-TCNTA1 be serviced while cabinet power is present?
        Honeywell lists module removal and insertion under power as supported for the C300 hardware. The connected process must still be placed in the approved maintenance state and site isolation and ESD procedures must be followed.
      • What environmental coating is specified for Honeywell 8C-TCNTA1?
        8C-TCNTA1 is conformally coated. Honeywell specifies G3 harsh-environment protection in accordance with ANSI/ISA S71.04-1985 for the C300 module and IOTA.
      • What I/O-link capacity is associated with Honeywell 8C-TCNTA1 and its C300 controller?
        The C300 supports two Series 8 I/O links at 750 kbps. Each link supports up to 40 I/O units, with up to 80 I/O units per controller.
      • What must be checked when moving Honeywell 8C-TCNTA1 from 8C-PCNT03 to 8C-PCNT05 hardware?
        8C-PCNT05 uses the same 8C-TCNTA1 IOTA and redundancy cable, but it supports Experion R520 and later and is not interoperable with 8C-PCNT03 as a redundant controller pair. Verify the project release and paired-controller identity before migration.
