1. DC resistance: The DC resistance in the good price and quality Electromagnetic relay can be measured by a multimeter.

2. Rated working voltage: Good price and quality Electromagnetic relay needs rated voltage when it works normally. According to different places and electrical models, good price and quality Electromagnetic relay can be AC or DC.

3. Pull-in current: good price and quality Electromagnetic relay produces the minimum current when it works and pulls in. Under normal and stable working conditions, the given current is greater than the pull-in current.

Introduction to the characteristics and main functions of good price and quality Electromagnetic relay

4. Release current: refers to the maximum current that occurs when the good price and quality Electromagnetic relay releases its action. The working current is less than the pull-in current, and the good price and quality Electromagnetic relay presents the release state in the non-energized state. .
