take measures to extinguish sparks to protect the relay contact (e.g. Z 

diode) or the transistor or 8/16 mA output.

Instruments with intrinsically safe current output

You can find detailed information on the explosion-protected versions 

(Ex-ia, Ex-d) in the Ex-specific safety instructions. These safety 

instructions are part of the scope of delivery and come with the Ex-

approved instruments.
