HONEYWELL CC-PDIS01 – Pulse/Discrete Input Module for Experion Series C and C300 I/O

The HONEYWELL CC-PDIS01 is a pulse/discrete input module designed for Experion Series C systems, typically paired with the C300 controller architecture. From my experience, it’s chosen when you need reliable counting of pulse signals (like turbine flowmeter pickups, proximity sensors, or totalizers) alongside clean 24 Vdc discrete inputs for interlocks and status points. It seems to be a natural fit for plants that want millisecond-level event visibility and stable long-run performance without constant tweaking.

• Pulse and discrete inputs on one module – Consolidates high-speed pulse counting and standard 24 Vdc status inputs, reducing cabinet footprint.

• Software-configurable channels – In many cases, input type, debounce, and scaling can be set in software, speeding commissioning.

• Event time-stamping – Typically supports millisecond-level SOE for critical events, making troubleshooting much faster during trips or alarms.

• Backplane integration with Series C – Communicates over the Series C I/O backplane, so no external converters or gateways are required.

• Hot-swap serviceability – Module replacement is usually possible without powering down the whole I/O segment, reducing downtime risk.

• Diagnostics and health monitoring – You might notice that channel- and module-level diagnostics help maintenance teams pinpoint wiring or signal issues early.

• Oil & Gas – Turbine flowmeter pulse counting, wellhead status, compressor skids.

• Chemicals & Petrochem – Batch totalizing, pump feedbacks, valve limit switches with event capture.

• Power & Utilities – Turbine/aux equipment status inputs, pulse signals from metering devices.

• Food & Beverage – Bottle/can line counting, packaging machine interlocks, throughput monitoring.

• Water & Wastewater – Flow totalizers, lift station run signals, gate/valve position status.

• Engineering efficiency – Combining pulse and discrete inputs on a single platform typically simplifies I/O lists and cabinets.

• Lifecycle reliability – Honeywell’s Series C ecosystem is known for long-term availability and stable firmware paths.

• Seamless Experion integration – Less time chasing drivers or third-party settings; trends, SOE, and diagnostics show up where you expect.

• Cost control – Fewer separate pulse counter modules and lower panel complexity can reduce total installed cost.

• Supportability – Access to Honeywell’s global spares and technical support network, which matters when uptime is critical.

• Cabinet and mounting – Install on the matching Series C IOTA/terminal assembly in a ventilated, dry cabinet; keep away from high-EMI sources where practical.

• Power and grounding – Use a clean 24 Vdc cabinet supply; bond shields at a single point and follow plant grounding standards to minimize noise on pulse lines.

• Field wiring – For pulse/frequency devices, shielded twisted pair is typically recommended; set debounce/filtering per sensor type (proximity, reed, or dry contact).

• Safety – De-energize field circuits before service; verify polarity on 24 Vdc inputs; respect SELV/PELV practices.

• Routine checks – Periodically review diagnostics, clean dust from vents, and confirm firmware/engineering station updates align with site change control.

• Spare parts – Keeping at least one spare CC-PDIS01 and the compatible IOTA on hand usually shortens MTTR during unplanned outages.

• Certifications – CE and UL/cUL compliance are standard for Series C modules; RoHS alignment is typical. Documentation can be provided upon request.

• Manufacturing quality – Produced under ISO 9001 quality systems.

• Warranty – Standard manufacturer’s warranty applies for new hardware (duration varies by region and supply program).

• Series C IOTA/terminal assembly matching CC-PDIS01 (for module mounting and field terminations)

• C300 controller within the Experion PKS architecture

• Appropriate cabinet 24 Vdc power supply with redundancy where required

If you’re aligning an upgrade or adding new pulse inputs to an existing Experion node, send the I/O list and we can verify channel counts, expected frequencies, and any debounce or scaling settings. You’ll avoid guesswork and, in most cases, shorten your commissioning window.
