NAMUR switches for postion feed back
NAMUR switches for postion feed back
(OP)
We have purchsed dsome actuated valves from Bettis with topworks posititon indicator
as pr the DS the open/ close limit switches are NAMUr type and certification EEXd
It dosent specift if it is SPDT or proximity type
do we have namur std switch in SPDT
or we need to buy Initiator tester 1-1350 and barrier in DCS panel?

RE: NAMUR switches for postion feed back
With NAMUR type, I assume they are proximitor types, need 24 Vdc supply and have none- isolated output. Check the drawing and instructions you got with the actuator or take the Topwork P.N and look for the instructions at the web.
