Beckhoff EL3102 2-Channel Differential Digital Input Module With 16-Bit Resolution

The Beckhoff EL3102 is a 2-channel differential analog input EtherCAT terminal with 16-bit high resolution. It is specially designed for precise collection of analog voltage and current signals from field industrial sensors. This module converts weak analog physical signals such as temperature, pressure, flow, weight and displacement into digital data, and transmits real-time high-precision data to the upper PLC host via the high-speed EtherCAT bus. It realizes distributed field analog signal acquisition, supports differential wiring to restrain external electromagnetic interference, and serves as the core signal acquisition unit in industrial closed-loop control systems, widely used for high-precision parameter monitoring and process automatic regulation of automated equipment.

• 16-bit high-resolution conversion, ensuring ultra-precise analog signal collection to meet high-standard industrial measurement demands
• Dual-channel differential input design, effectively suppresses common-mode inerference, stable signal acquisition in strong electromagnetic workshop environments
• High-speed EtherCAT real-time bus transmission, short conversion response time, supports synchronous multi-module signal collection
• Compact narrow-body terminal structure, DIN rail installation, greatly saving electrical cabinet internal layout space
• Hot-swappable design, allows on-site module replacement without shutting down the entire automation control system
• Wide industrial temperature working range, industrial-grade anti-interference circuit design, strong environmental adaptability
• Flexible signal configuration, compatible with standard industrial voltage and current analog signals, convenient parameter configuration and debugging
• Overvoltage and reverse wiring protection for each channel, effectively preventing module damage caused by field wiring errors
