WebMar 24, 2015 · This is the second section of an Introduction to Reed Relay Basics. For a simple explanation of what a reed switch is and generating the magnetic field please read ' Reed Relay Basics Part 1 '. Normally open reed relays are by far the most common configuration of reed relay. However, normally closed relays can also be supplied where … WebMost of the time, failsafe circuits use normally open contacts for interlock chains. In the case discussed above, however, a set of normally closed contacts was properly used. This was proper because the level switches used here are dumb— unpowered, non-electronic switches that switch the state of their outputs strictly based on pressure.
WebHere, both the pressure switch and the relay contact (CR1-1) are drawn as normally-closed switch contacts. This means the pressure switch contact will be closed when the applied … WebHIC SDD-10HDZ Solid state relay is a 10A one channel normally open normally closed dc solid state relay with 10A current load current. 35mm din rail-mounted socket, 10A operating current, it is very convenient to use. …
