But in real-world conditions when we are choosing the instrument switches or other types of discrete equipment for a process, we have to select which one should work with a Normally Open contact and which one should work with a Normally Closed contact. So, in this video, we'll answer these questions and investigate the real-world application examples of Normally Open and Normally Closed Contacts such as Contactors and relays, pushbuttons, instrument switches, and so on. We also will have a quick look at the NAMUR sensors at the end of this video. =========================== ✅ Please SUBSCRIBE to get notified about the new videos: https://bit.ly/32mlhu9 =========================== SECTIONS of this video: 0:00 important questions about NO and NC contacts 0:59 different types of discrete signals in the industry 1:27 NC and NO contacts application in a contactor (Example) 2:05 NC vs NO sensor (Example) 3:52 why normally closed contacts should be integrated into stop push buttons? 4:37 NAMUR switches instead of normal switches =========================== ▶ If you've missed our most recent videos, watch them here: DCS vs PLC: 5 Important Differences between PLC and DCS https://upmation.com/plc-vs-dcs/ What is a Directional Control Valve?
