Schneider 140EHC10500 Modicon High-Speed Counter Module

Description

Schneider 140EHC10500 Modicon High-Speed Counter Module is part of the Modicon Quantum series, engineered for high reliability and performance in industrial automation systems. This 5-channel discrete incremental counter module supports flexible counting modes including single pulse, dual pulse, incremental counting, encoder counting, 32-bit event counting, 32-bit differential counting, 16-bit repeat counting, and 32-bit rate counting, configurable via UnityPro software. It delivers high precision with a counting accuracy of up to 0.01% and supports maximum counting frequencies of 100kHz at 5V DC and 20kHz at 24V DC, with a 1/1 duty cycle. Key electrical specifications include a maximum 30V DC counting input voltage, 7mA counting input current, and 5mA discrete input current, plus 5000Vrms isolation between inputs and outputs and internal output short-circuit protection for enhanced durability. Physically, it measures approximately 155mm x 110mm x 40mm, weighs 0.3kg, features DIN rail mounting, and has an IP20 protection rating for use inside control cabinets. It can transmit count values to the CPU on each scan or perform asynchronous updates to reduce unnecessary communication. Ideal for applications like production line speed measurement, encoder interfacing, servo motor control, machine cycle counting, and material counting, it is widely used in industrial automation, process control, building automation, manufacturing, energy, and rail transit sectors.
