Hi, I am currently researching the appropriate standards (UL, CSA, IEC) for a position indicator. The indicator is mounted on a valve. It indicates whether the valve is open or closed. It is a 10 to 30 Vdc, 150 mA, PNP device. The valve is used in the pharmaceutical industry and controls the flow of sterile liquids.
After doing some research, I have come up with two options. 1. Laboratory, control and measurement equipment. UL 3101-1, CSA 1010.1 and IEC 61010-1 2. Proximity switches. IEC 60947-5-2, UL 508 (I don't think the UL version of IEC 60947-5-2), CSA ?? Does anyone have any comments or ideas? Thanks Ned Devine Entela, Inc.
