I would like to set up a valve control unit in a Class 1 Div 1 rated area. The control unit uses an electronic positioner that has no explosion proof qualification.
- Power supply is 24 VDC
- Output to solenoid valves is 24 VDC
- Control and feedback signal are 4-20 mA (low power)
I will place the positioner in a Class 1, Div 1 FM/UL certified junction box.
Question 1
Do I need to use conduit couplings, seals and conduit tubing or does anyone know of Class 1 Div 1 cable glands?
Question 2
Am I allowed to place the uncertified positioner in the junction box or does the positioner need to be FM/UL listed?
Thanks for your help.
