Schneider Electric 140EHC20200 High Speed Counter

Schneider Electric 140EHC20200 High Speed Counter is a two-channel counter module designed for Modicon M340 controllers within the Quantum automation platform, delivering pulse counting up to 500,000 Hz. It expands the controller’s capability to track fast digital inputs and is intended for integration in Modicon Quantum/M340 racks where high-speed event counting is required. The part number 140EHC20200 is officially documented as the high-speed counter module with two channels, and Schneider Electric lists BMXEHC0200 as the recommended replacement for this model. The 140EHC20200 has been discontinued for commercialization; Schneider Electric notes an end-of-commercialization date and a separate end-of-service date of December 31, 2030, after which formal sales and support are limited. This module is part of Schneider Electric’s Modicon Quantum family and is used in projects that demand reliable, high-frequency counting without overloading the main PLC processor.
