Quick-break valve switch feedback
Thread Content
For the switch feedback of the quick-break valve, are it usually two signals sent to the DCS? Could you send me an internal wiring diagram? A wiring diagram from the site will work as well
There should be six terminals, three for feedback on and three for feedback off. There are two COMs, as well as two each for normally open and normally closed. Generally, a COM terminal and normally open contacts are used.
Open the cover; there’s a wiring diagram on the back of it
Look at the valve you ordered; it’s really not good.
Open the cover – the wiring diagram is attached inside the upper cover. If the owner wants to purchase it, contact me; they are properly made position switches and actuators.
{:3_54:} It’s an image from the internet; I was looking for the wiring diagram on it
It’s actually quite simple: two feedback signals, for opening and closing the valve, which just need to be connected to the digital I/O cards of the DCS
There are four signals inside: normally open and normally closed when in the activated position； Normal open and normal closed for shutdown signals ； It could be three-wire or two-wire. . There are no photos from the scene. . :lol
Actually, it’s just a on/off signal; no wiring diagram is needed. You can use a multimeter to measure and adjust the cam contacts inside in order to determine its function
The image you found has a manual valve; just turn it on and off by yourself, and then use a multimeter to check it! Moreover, by opening the cover, one can see a limit switch inside, and it can also be determined through the wiring there! I think this isn’t difficult; it’s the most basic thing
