PRODUCT DESCRIPTION
BECKHOFF ELX3632 - 2-Channel Intrinsically Safe Analog Input Terminal
This EtherCAT Terminal is an intrinsically safe analog input module from the ELX series, engineered for precise resistance measurement in hazardous environments. It facilitates the direct connection of 2-, 3-, or 4-wire RTD sensors and thermistors (e.g., Pt100, Pt1000) to an EtherCAT network, ensuring reliable temperature acquisition in process automation applications requiring explosion protection.
