Model Selection and Functional Differences

The suffix letters of G2R-2 represent different functional configurations:

-에스: 표준형, no additional functions.

-SN: Built-in operation indicator light (주도의), supporting circuit status monitoring.

-SD: Built-in freewheeling diode, protecting the circuit from back EMF (electromotive force) 영향, 유도 부하에 적합.

-SND: Integrates both LED indicator light and diode, ideal for scenarios requiring status feedback and protection.

(에스): Equipped with a mechanical operation lever, facilitating manual circuit testing.

예를 들어, G2R-2-SN DC24 refers to a DPDT relay with a DC24V coil and built-in LED indicator; G2R-2-SD AC120 is a model with an AC120V coil and built-in diode.

III. 응용 시나리오
