Pulse Input Counter Module 8C-PCNT01 Honeywell

Product Description

The 8C-PCNT01 is a high-speed Pulse Input Module engineered for the Honeywell Experion PKS C300 / Series 8 platform. It is designed to accurately capture, count, and process digital pulse streams from field devices such as flowmeters, rotary encoders, and velocity sensors.

This module provides high-integrity accumulation data and frequency measurement in fast industrial processes. Advanced hardware-based filtering eliminates contact bounce and electrical noise, while seamless integration with the C300 controller allows millisecond-accurate updates to control logic. It is ideal for custody transfer, dosing, turbine monitoring, and high-speed counting applications.

Technical Specifications

Industrial Application

The 8C-PCNT01 is widely deployed in oil & gas, manufacturing, and process industries for:

• Turbine meter monitoring

• Encoder-based positioning and speed control

• Flow totalization and custody transfer

Its capability to handle high-frequency pulse inputs makes it essential for applications where precision and operational efficiency are critical.

Frequently Asked Questions

Q: What is the difference between a standard DI and the 8C-PCNT01?
A: Unlike standard Digital Input modules, which detect simple state changes, the 8C-PCNT01 features dedicated high-speed hardware to count pulses up to several kHz without loss due to controller scan times.

Q: Does this module support dual-pulse inputs for error detection?
A: Yes. The module can monitor dual-pulse streams from high-precision meters to ensure measurement validity and meet regulatory standards.
