2.5.1 Introduction
Fig. 18: EL3318
8 channel HD analog thermocouple input terminal with open-circuit recognition
The EL3318 analog input terminal allows direct connection of eight thermocouples and is therefore
particularly suitable for space-saving use in control cabinets. The EtherCAT Terminal circuit can operate
thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole
temperature range, which is freely selectable. The error LEDs indicate a broken wire. Compensation for the
cold junction is made through an internal temperature measurement at the terminals. The EL3318 also
enables measurements in the mV range.
The HD EtherCAT Terminals (High Density) with increased packing density are equipped with 16 connection
points in the housing of a 12-mm terminal block.
