EL3602 is a 2-channel analog input terminal of the Beckhoff EtherCAT I/O system. It is used to connect analog sensors or signals to a Beckhoff PLC system. The EL3602 module supports various types of analog input signals, including voltage, current, and temperature measurements. It has a resolution of 12 bits and supports sampling rates up to 10 kHz per channel. The EL3602 terminal can be integrated into a Beckhoff PLC system via an EtherCAT fieldbus connection, allowing for fast and reliable data exchange between the terminal and the PLC controller.
