Relay Logic Circuit Examples. The contacts are connected in series for and gate. Following line diagram for this example.
Engine auto start control. Two time delay relays are used in conjunction with one another to provide a constant frequency on off pulsing of contacts for sending intermittent power to a lamp. Predict how the operation of this relay logic circuit will be affected as a result of the following faults.
In this the pilot lamp will turn on whenever any one of the inputs becomes one which makes the.
Logic schematics can be drawn to illustrate how different protection elements are wired. The second line has a normally open contact from relay no 1 also labelled r1 which is connected to lamp no 1. Relay logic is all about wiring up relays for logical switching applications. Relay logic provides you with a guide for using ncd relay controllers and how they can be wired for many types of applications.
