The measurement technology instruments in the ELM3xxx series are powerful EtherCAT measurement modules in IP20. They can be combined with other EtherCAT Terminals, of which more than 800 are available, on the DIN rail in the control cabinet using practically any configuration to suit the requirements of the application. The ELM3 measuring instruments are divided into 2 classes: the ELM3x0x basic series for faster measuring processes and the ELM3x4x economy series for slower measuring processes.
