140EHC20200 | Schneider Electric | High-Speed Counter

Product Description

Precision Pulse Counting and Motion Interface

The Schneider Electric 140EHC20200 (also identified as 140-EHC-202-00) is a high-performance high-speed counter (HSC) module specifically engineered for the Modicon Quantum PLC platform. This module is essential for applications requiring deterministic pulse acquisition that exceeds the scanning capabilities of standard discrete inputs. By offloading counting tasks from the main CPU, the 140EHC20200 ensures accurate position tracking, frequency measurement, and speed monitoring for complex industrial machinery.

High-Frequency Signal Integrity

The 140EHC20200 features two independent high-speed channels capable of processing pulse signals at frequencies up to 1 MHz. This makes it highly effective for interfacing with incremental encoders, flow meters, and high-speed proximity sensors. The module supports versatile operational modes including up/down counting and position sensing. To maintain system reliability in electrically noisy industrial environments, each channel is protected by galvanic isolation. Comprehensive front-panel LED diagnostics allow engineers to monitor channel activity and detect fault conditions instantly, ensuring maximum system uptime in motion control and packaging applications.
