Honeywell TC-PCICO1K Pulse Counter I/O Module

Honeywell TC-PCICO1K — Stop the Clock on Your Downtime. Ship Today from Xiamen.

Every minute a TPS / TDC 3000 node sits offline, your plant is bleeding money. Flow totals drift, batch records break, and your operations team is staring at a blank faceplate. The TC-PCICO1K Pulse Counter I/O Module is the exact card that puts your loop back in service — and we have it on the shelf right now, tested, documented, and ready to clear customs before your next shift change.

We are not a catalogue site. We are a stocking distributor with a warehouse in Xiamen, China, staffed by engineers who have pulled these cards from live TPS cabinets. When you send us a purchase order at 11 PM, we are already packing the box.

Troubleshooting & Replacement Tips

Common failure signatures for TC-PCICO1K:

• FAIL LED solid red on card faceplate — Most often a firmware mismatch after an HPM upgrade. Before condemning the card, check the HPM revision against the I/O Link firmware table in the TPS System Release Notes. A card that worked fine for five years can throw a FAIL after a controller patch.
• Pulse count freezing or rolling over incorrectly — Inspect the field wiring first. TC-PCICO1K is sensitive to ground loops on the pulse input lines. Verify shield termination at one end only (panel side). A floating shield on a turbine meter cable is the most common culprit in refinery environments.
• Intermittent COMM FAIL on LCN — Reseat the card in the chassis. TPS card-edge connectors oxidize in humid environments. Use DeoxIT D5 on the gold fingers before reinsertion. If the fault persists after reseating, swap the I/O Link cable assembly (TC-CCR014 / TC-CCR024) before replacing the module itself — cables fail more often than the card.
• Module not recognized after hot-swap — TPS requires the replacement card to match the firmware revision of the outgoing unit. Pull the firmware label from the faceplate of the failed card before ordering. If revisions differ, the HPM will reject the new card at initialization. Contact us with your revision requirement — we stock multiple firmware variants.

Step-by-step replacement procedure (field-tested):

1. Confirm the HPM has placed the affected I/O point in manual or has a redundant path active. Do not pull the card with live control loops in auto.
2. Document the slot address and I/O Link node number from the TPS Engineering Console before removal. You will need this for re-commissioning.
3. Loosen the card retaining screw (Phillips M3) at the top of the faceplate. Grip the extraction handle — do not pull by the faceplate label.
4. Insert the replacement TC-PCICO1K. Seat firmly until the card-edge connector is fully engaged. Tighten the retaining screw finger-tight.
5. At the HPM console, perform a card initialization command for the slot. The module will self-address from the chassis backplane — no DIP switch setting is required on this model. The LCN node address is assigned by the HPM, not by hardware jumpers.
6. Verify the ACTIVE LED goes green within 30 seconds. If it does not, check that the firmware revision on the replacement card matches the HPM’s expected revision table.
7. Restore the I/O point from manual to auto. Confirm pulse counts are incrementing correctly against a known flow reference before releasing to operations.

Configuration note — no DIP switches, but firmware matters: Unlike older TDC 3000 I/O cards that required manual address selection via rotary switches, the TC-PCICO1K uses automatic slot addressing via the LCN backplane. The only configuration variable that will cause a rejection is a firmware revision mismatch. Always confirm the firmware suffix (e.g., TC-PCICO1K/R110) before ordering a replacement.

Reliability in Harsh Conditions

TPS systems were engineered for continuous operation in environments that would destroy consumer-grade electronics. The TC-PCICO1K reflects that design philosophy. The card’s PCB uses conformal coating on all signal traces, providing a moisture barrier rated for operation in relative humidity up to 95% non-condensing — a real-world requirement in coastal refineries and tropical chemical plants where cabinet door seals degrade over time.

Vibration tolerance is validated to IEC 60068-2-6 test profiles, covering the 5–150 Hz frequency range at 1 g acceleration — sufficient for installation in pump rooms and compressor buildings where structural vibration is a daily reality. The card-edge connector uses gold-plated contacts with a wipe-action design that maintains electrical continuity even when the chassis experiences minor thermal expansion and contraction cycles across a 24-hour day-night temperature swing.

Thermal management is passive — no fans, no moving parts. The card dissipates heat through the chassis backplane and card cage airflow. In installations where cabinet cooling has degraded, the TC-PCICO1K will typically show intermittent COMM errors before a hard failure, giving maintenance teams a warning window to act. If you are seeing unexplained intermittent faults on a card that passes bench testing, check the cabinet ambient temperature before replacing the module.

Every unit we ship has been stored in a climate-controlled warehouse in Xiamen. Cards are individually bagged in anti-static ESD packaging with silica gel desiccant. We do not stack cards loose in bins. When your replacement arrives, it is in the same condition it left the original plant — or better, because we have cleaned the contacts and run a power-on functional test before it left our facility.

Global Express Logistics

Our warehouse is located in Xiamen, Fujian Province — one of China’s primary export hubs with direct access to Xiamen Gaoqi International Airport and the Port of Xiamen. This geography is not accidental. It means your urgent order moves from our shelf to an international carrier in hours, not days.

Standard express routing:

• Southeast Asia (Singapore, Thailand, Malaysia, Indonesia): DHL Express or FedEx International Priority — typical transit 1–2 business days from dispatch.
• Middle East (UAE, Saudi Arabia, Kuwait, Qatar): FedEx International Priority or DHL Express — typical transit 2–3 business days.
• Europe (Germany, Netherlands, UK, France, Italy): DHL Express Worldwide — typical transit 3–4 business days. We prepare all export documentation including commercial invoice, packing list, and HS code declaration (HS 8537.10) to prevent customs delays.
• North America (USA, Canada, Mexico): FedEx International Priority or DHL Express — typical transit 3–5 business days. We can provide a formal export license declaration if required by your import broker.
• South America and Africa: DHL Express — transit varies by destination; we will confirm lead time at order placement.

For plant turnaround situations where every hour counts, we offer same-day dispatch on orders confirmed before 14:00 CST (UTC+8). We will send you the AWB tracking number within two hours of handover to the carrier. If your freight forwarder requires a specific carrier account number for billing, we accommodate that — just include it in your purchase order.

All shipments include full commercial documentation for customs clearance. We have shipped to over 40 countries and understand the import requirements for industrial automation components in each major market. We will not let a paperwork error hold your part at customs when your plant is down.
