▊Coil parameters
Rated voltage DC（V） | Action voltage VDC | Release voltage VDC | Maximum voltage VDC | Coil resistance ω |
24 | ≤18.0 | ≥2.4 | 31.2 | 1600×（1±10%） |
Remarks:
1. The above values are all initial values;
2. The maximum voltage refers to the maximum voltage that the relay coil can bear in a short time;
3. For products with rated voltage ≥48V, in order to protect the coil from operation, measures must be taken to suppress the overvoltage of the coil during testing and application (such as connecting diodes in parallel with the coil).
