The EL3314-0092 analog input terminal facilitates the direct connection of four thermocouples in a 2-wire configuration. The channels are electrically isolated from each other and from the E-bus, which effectively prevents adverse effects and damage due to cross currents. Various types of thermocouples are supported, and voltage-to-temperature conversions take place within the terminal. The terminal also allows for mV measurements. Wire breaks are signaled by error-LEDs, as well as on the fieldbus. Cold junction compensation is carried out by an internal precise temperature measurement at the connection terminals; however, operation with an external cold junction is also possible.
The EL3314-0092 also supports TwinSAFE SC (TwinSAFE Single Channel). This enables the use of standard signals for safety tasks in any networks or fieldbuses.
