Beckhoff EL3102 EtherCAT 2-Channel Analog Input Terminal
1. Product Overview
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.
2. Product Advantages & Core Features
