The EL3318 is an EtherCAT terminal designed for analog input with 8 channels for temperature measurement using thermocouples, offering 16-bit resolution. It supports the direct connection of eight thermocouples and is suitable for space-saving use in control cabinets. The terminal operates thermocouple sensors using a 2-wire technique. A microprocessor handles linearization across the entire selectable temperature range.
