Product Description

The BH4M-PDT counter module is designed for industrial automation applications, featuring 4 high-speed encoder inputs with a counting frequency of up to 500 kHz and 2 isolated PLC pulse interface outputs for seamless integration into control systems. It supports direct connection to up to 8 expansion modules, enabling scalable configurations. Equipped with RS-485 and Ethernet communication interfaces, the module operates within a voltage range of 12-24V DC and withstands industrial temperatures from -20°C to +60°C. Its compact design includes a 2.4-inch LCD screen for real-time data monitoring and a built-in 2000mAh backup battery to maintain counter data during power interruptions. Ideal for machinery, conveyor systems, and motion control, the BH4M-PDT offers robust performance with minimal latency but requires dedicated software for advanced parameterization. Detection ranges extend up to 10 meters for encoder-based applications.
