Description

The ELX3202-0090 analog input terminal allows the direct connection of RTDs located in hazardous areas classified Zone 0/20 or 1/21. The circuitry of the ELX3202-0090 can operate sensors with 2, 3 and 4-wire technology. Linearisation is carried out over the entire freely selectable temperature range. By default the terminal is set to PT100 sensors with 3-wire technology. The ELX3202-0090 terminal indicates signal state and sensor malfunctions (e.g. wire breakage) by means of LEDs.
