(15) Description of equipment
The Ex-Separator-Module type iXT0-xxx is used for supply of sensors and for communication of
sensors with measuring transmitters.
The following executions of the Ex-Separator-Module type iXT0-xxx are available:
- iXT0-420: Ex-Separator-Module for connection to 4 x RS485 and 2 x 2 wire sensors
- iXT0-421: Ex-Separator-Module for connection to 4 x RS485 and 2 x 2 wire sensors with 1 x HART
function
- iXT0-21 0: Ex-Separator-Module for connection to 2 x RS485 and 1 x 2 wire sensors
- iXT0-211: Ex-Separator-Module for connection to 2 x RS485 and 1 x 2 wire sensors with 1 x HART
function
The permissible ambient temperature range is -20 °C ... +40 °C.
