6.3. Technical specifications of the analog extension
The analog extensions are powered at 5 V and 24 V d.c. by the central unit or extensible
remote unit to which they are connected.
The analog value with a customized format of each channel is displayed on a 4 digit display.
The channel number is selected by the push button on the front side.
Warning: the extensions must not be connected or disconnected under power supply.
Warning: In the configuration current 4 – 20 mA, the sensor should be able to provide 20 mA
with min 10 V d.c. Moreover, the input is not protected against voltage between 10 up to 18 V
d.c. and can give an error or destroy the input.
