BMXDDI1602H Discrete Input Module Schneider

Description

The BMXDDI1602H Discrete Input Module is part of the Schneider Modicon X80 series, designed for industrial automation signal acquisition and processing. It features 16 discrete input channels, optimized for 24V DC positive logic (current sinking) input, with each channel drawing a nominal 3.5mA input current. The module supports both dry and wet contact inputs, compatible with NPN and PNP sensors, and offers configurable input types including sinking and sourcing logic to suit diverse field device requirements.

Engineered for harsh industrial environments, it provides high anti-interference capability and reliable performance, with an operating temperature range of 0 degrees Celsius to 60 degrees Celsius and storage temperature range of -25 degrees Celsius to 70 degrees Celsius. Key technical specifications include channel group isolation (8 channels per group, 2 total groups) with optoelectronic isolation between inputs and internal PLC circuits, a typical response time of 1.5ms with configurable filtering, and power supplied via the Modicon M340 backplane bus, eliminating the need for external power. It uses pluggable spring terminal blocks compatible with 0.2 to 2.5 square meters wire, and mounts on standard 35mm DIN rails with an IP20 protection rating for cabinet installation. Integrated diagnostic functions enable real-time monitoring of input status and module health, and it seamlessly integrates with Modicon M340 and M580 PLC systems. Ideal applications include industrial production lines, process control systems, and smart building automation for monitoring switch states, sensor signals, and equipment operation status.
