The 24-Z Dry Contact Input Module by Moncef EL KanetS is a robust and high-density 24-channel dry contact interface module, built for advanced home automation, industrial control, building management systems (BMS), and security applications. Designed for reliability and scalability, this professional-grade module allows seamless monitoring of 24 independent dry contact inputs — such as push buttons, door contacts, limit switches, and relay outputs — all through a single, compact unit.

Each channel is opto-isolated, offering noise immunity and electrical isolation, making it ideal for environments with high EMI or safety-critical operations. The module is compatible with popular controllers like Arduino, ESP32, Raspberry Pi, PLC systems, and SCADA platforms, enabling easy integration into IoT, BMS, and access control systems.

Whether you’re building a large-scale automation hub or enhancing security infrastructure, the 24-Z Dry Contact Input Module ensures accurate, fast, and safe signal reading across multiple zones.
