What does K1 stand for on a P&ID Diagram?

Explanation:
K1 on a P&ID diagram identifies a relay coil. In these diagrams, the designator K is used for relays or contactors, and the accompanying number simply names which relay it is in the circuit. So K1 means the first relay coil in the control loop. Relays are used to control larger loads with a smaller control signal, and the K designation helps you follow the coil and its associated contacts throughout the diagram. The other descriptions refer to network standards or unrelated terms, not to a relay designation on a P&ID, which is why they don’t fit.
