WebGenerally speaking, there are three types of digital or discrete signals in the industry. – First, the Instrument Switches like Level switches, Flow switches, and so on. – Second, Operator Push buttons like Start and Stop push buttons, Emergency push buttons, and so on. – Third, the Digital Feedbacks from Contactors and relays.. The Open and Closed contacts can … WebApplication of Relay. The application of control systems and automation circuits need the logic state and logic gates. The logic gates are represented by open and closed state of switches or relays. Later we will use the terms of NO (Normally Open) and NC (Normally closed) when talking about relays and switches when the coil is generated.
