Product Overview

The CC-TPIX11 is a pulse input I/O module used in Honeywell Experion PKS C300 / Series C architectures for acquiring high-speed pulse and frequency signals from field devices. It is designed for applications where pulse measurement accuracy and signal integrity are required, including flow pulse pickup, rotational speed sensing, and metering systems. The module supports flexible channel configuration, allowing it to be set up as eight independent pulse inputs for maximum frequency capability or as four dual-input channels for quadrature (A/B) encoder measurements.

Electrical isolation and differential input design help protect the control system from ground potential differences and transient disturbances, improving reliability in electrically noisy plant environments. The module also supports common pulse-processing functions used by control and measurement strategies, such as frequency and period measurement and totalization.

Signal and Electrical Characteristics

• Channel configuration options

• 8 single pulse input channels

• 4 dual-pulse channels for quadrature encoder applications

• Mixed configuration support depending on project requirements

• Measurement capability

• Frequency range: 0 to 100 kHz in single-channel mode (typical)

• Frequency accuracy: ±0.001% (typical, application dependent)

• Input design

• High-impedance differential pulse inputs

• Selectable edge detection (rising or falling)

• Configurable input threshold/trip levels to match sensor output characteristics

• Isolation

• Optical isolation rated to 1000 VDC (typical) for improved noise immunity and ground-loop reduction

• Power/excitation support

• Supports internal 24 VDC supply usage and external excitation options (typical 5 to 30 VDC depending on wiring design)

• Output functions

• Includes output channels for driving external indication or alarm devices (implementation dependent)

Industrial Applications

• Pulse-output flowmeter signal acquisition for flow measurement and totalization

• Turbine and rotating equipment speed monitoring using magnetic pickups or pulse sensors

• Gas measurement skids and metering stations using high-frequency pulse streams

• Quadrature encoder monitoring for position/speed applications using dual-channel A/B signals

• Critical process loops that require redundant I/O behavior to reduce measurement interruption risk
