EL3314-0002 | EtherCAT Terminal, 4-channel analog input, temperature, thermocouple, 24 bit, electrically isolated
EL3314-0002 | EtherCAT Terminal, 4-channel analog input, temperature, thermocouple, 24 bit, electrically isolated
Thermocouple measurement with Beckhoff components: precise and fast
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The EL3314-0002 analog input terminal allows the direct 2-wire connection of four thermocouples. The channels are electrically isolated from one another and from the E-bus, thus preventing interference and damage due to cross-currents. Various types of thermocouple are supported; the voltage is calculated in temperature directly in the terminal. The terminal can also be used for mV measurements. A broken wire is signaled by the error LEDs and on the fieldbus. Cold junction compensation takes place by means of precise internal temperature measurement at the connecting terminals, but operation with an external cold junction is also possible.
