Introduction
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.
