EPX3204-0022 | EtherCAT Box, 4-channel analog input, temperature, RTD (Pt100), 16 bit, M12, Ex i
The EPX3204-0022 EtherCAT Box enables direct connection of RTDs from zone 0/20 and 1/21 hazardous areas. The EPX3204-0022 circuit can operate sensors in 2-wire, 3-wire and 4-wire technology. Linearization takes place across the entire, freely selectable temperature range. By default, the terminal is set to Pt100 sensors in 4-wire technology. The EPX3204-0022 indicates signal state and sensor faults (e.g. wire break) by means of LEDs.
