Main products of relay technical parameters

1. Rated working voltage

The voltage required by the coil for the relay to work normally.Depending on the type of relay, it can be either ac or DC.


2. Dc resistance

Refers to the dc resistance of the coil in the relay, which can be measured by the multimeter.


3. Absorption current

Refers to the relay can produce the minimum current suction action.In normal use, the given current must be slightly greater than the suction current for the relay to work stably.And for the working voltage added by 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 the current

Refers to the maximum current generated by the relay to release the action.When the current in the relay suction state decreases to a certain extent, the relay will revert to the release state without energizing.The current is much less than the suction current. 


5. Contact switching voltage and current

The voltage and current allowed to be loaded by the relay.It determines that the relay can control the voltage and current, which cannot be exceeded when used, otherwise it is easy to damage the relay contacts.
