Relay main product technical parameters
Relay main product technical parameters
1. Rated operating voltage
It refers to the voltage required by the coil when the relay is working normally. Depending on the type of relay, it can be either AC or DC voltage.
2. Dc resistance
Refers to the DC resistance of the coil in the relay, which can be measured by a multimeter.
3. Suction current
Refers to the minimum current that the relay can generate the draw action. In normal use, the given current must be slightly greater than the draw current for the relay to be stable
To work. The working voltage added to the coil, generally do not exceed 1.5 times of the rated working voltage, otherwise it will produce a large current and burn the coil.
4. Release current
Is the maximum current generated by the relay to release the action. When the current of the relay is reduced to a certain extent, the relay will return to the unenergized release
Put the state. The current is much less than the suction current.
5, contact switch voltage and current
The voltage and current that the relay is allowed to load. It determines the size of the voltage and current that the relay can control, and cannot exceed this value when used, otherwise it is easy
Damaged relay contacts.
