Web4 de out. de 2013 · You know that 1 and 16 are the coil because the're not part of the switch, and the relay in a de-energised state will have the switch in the NC position, thus implying that the commons are 4 and 13 (seen as they don't change), 6 and 11 are normally closed and so 8 and 9 must be the normally open. WebStep 4: Identify NC, NO & C. Most of the relays have the abbreviations (NO, NC, C) printed near the leads. If its not, follow these simple steps to identify them:-. 1) C (common) can be easily recognised as it is placed in the middle of any one of the side of a relay. 2) Coil terminal lies besides the Common terminal.
