CF9 IOTA · 9 × RJ-45 · Spare 51308301-175
CC-TCF901 / 51308301-175 — Honeywell CF9 Nine-Port Control Firewall IOTA
CC-TCF901 (spare 51308301-175) is not a process analog or digital I/O board. It is the Input/Output Termination Assembly for Honeywell’s nine-port Control Firewall (CF9). The firewall electronics (CC-PCF901) plug into this IOTA and form the Fault Tolerant Ethernet (FTE) center for a Series C control network. HKXY Instruments is a China industrial automation trader with 15 years of export experience, not the OEM.

What CF9 does on the Series C network
Honeywell’s Control Firewall User’s Guide describes CF9 as the FTE communications center for a given Series C control network. The eight downlink ports connect C300 controllers and Series C FIMs inside the cabinet, and may also connect FTE Bridge modules (FTEB) in a Series A chassis. The ninth port uplinks to the supervisory FTE network and level-2 control area.
Documented security/traffic behaviors include rejecting Ethernet messages that are not needed for control, giving downlink traffic priority over uplink ingress if the fabric saturates, and allowing only valid C300-compliant messages into the C300 domain.
Power and optional fiber
- CC-PCF901 supply rating documented at 0.112 A @ 24 VDC.
- Optional FTE fiber modules: CC-FSMX01 single-mode (dual-jacketed dual-fiber, yellow, LC connector, 9/125 glass, 1300 nm) and multi-mode counterpart CC-FMMX01 / Ca-FMMx01. Fiber-module supply is documented at 0.30 mA @ 24 VDC — confirm the exact fiber model from the installed hardware [TO CONFIRM].
Honeywell connection rules that affect spare planning
- The Control Firewall uplink must be connected to a Cisco switch (as stated in the Control Firewall User’s Guide).
- Do not stack Control Firewalls.
- Connect the firewall to an interface configured for portfast.
- Connect Series C FIMs and C300s to a Control Firewall.
- An FTEB that communicates with a C300 must share the same Control Firewall as that C300.
- Honeywell documents that it is invalid for a CF9 to host a C200 through an FTEB; an FTEB on a CF9 is valid only in the Series A FIM case described in the guide.
These are engineering constraints, not sales promises. Follow the current Honeywell bookset for the installed Experion release.
RFQ checklist
- Photograph CC-TCF901 / 51308301-175 and the plugged-in CC-PCF901 (or CU- equivalents).
- Sketch the eight downlink destinations (C300, FIM, FTEB) and the uplink switch port.
- Note any CC-FSMX01 / CC-FMMX01 fiber module and cable type.
- Confirm coated vs uncoated (CC- vs CU-) and revision.
- Quantity, destination, inspection scope. Stock, price, and lead time are [TO CONFIRM].

FAQ
Is CC-TCF901 a C300 controller or I/O module?
Neither. It is the termination assembly for the nine-port Control Firewall.
What module plugs onto it?
CC-PCF901 (coated) or CU-PCF901 (uncoated).
How are the nine ports used?
Eight FTE downlinks for in-cabinet C300s and Series C FIMs (and documented FTEB cases) plus one uplink to the supervisory FTE network.
Can I use CC-TCF901 without checking switch type?
Honeywell’s guide requires the uplink to a Cisco switch and forbids stacking firewalls. Validate against the site network design.
Is a price published here?
No. Commercial terms are [TO CONFIRM] after label review.
