Beckhoff EL3204 is a four-channel EtherCAT analog-input terminal that combines two Pt100 RTD channels for direct temperature sensing with two -10 V input channels for voltage measurement on a single module. The device delivers 16-bit resolution on its inputs, enabling precise RTD temperature readings and accurate voltage capture. As part of Beckhoff's EtherCAT terminal family, the EL3204 integrates into a Beckhoff automation system for fast, deterministic data transfer and streamlined diagnostics. Typical applications include temperature monitoring with Pt100 RTDs in HVAC, process control, and laboratory instrumentation.
