1. 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: 내장형 프리휠링 다이오드, 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

1. 산업 자동화

– Controls actuators such as motors, 솔레노이드 밸브, and contactors, supporting PLC system linkage.

– Typical cases: Signal switching for assembly line equipment, sensor-triggered logic control.

2. Smart Home and Consumer Electronics

– Drives smart switches, curtain motors, and security devices, compatible with development boards like Arduino and ESP32.

– 예: When remotely controlling home appliances via a voice assistant, the G2R-2 can act as a bridge between low-voltage signals and high-voltage loads.

3. New Energy and Power Systems

– Used for battery charge-discharge management and circuit switching of energy storage equipment, meeting high-reliability requirements.

– 예: Controls the on-off of charging circuits in 전기 같은 vehicle charging piles.

4. Medical and Transportation Equipment

– Enables precise control of medical instruments (예를 들어, infusion pumps) and status switching of traffic signals.

1. 설치 및 액세서리
2. Sockets and Terminals

– It is recommended to use Push-In Plus sockets such as P2RFZ-08이자형, which support quick wiring and reduce installation time by 60%.

– Matching terminal covers (P2CZ-C) and jumper bars (PYDN series) can enhance safety and flexibility.

2. 지침

– AC/DC coils are distinguished by tape color (예를 들어, blue for DC, white for AC) to avoid incorrect connection.

– 설치 중, ensure that the contact load does not exceed the rated value; for inductive loads, a diode or RC snubber circuit must be used in conjunction.

1. Procurement and Alternative Solutions
2. Supply and Price

– In the U.S. 시장, it can be purchased via WhatsApp: 0086-13811255435. 예를 들어, the spot price of G2R-2-S DC12(에스) 대략이다 11.71 미국 달러.

– 일부 모델 (예를 들어, G2R-2-SNI) have been discontinued; it is recommended to prioritize G2R-2-S or G2RL-2A as alternatives.

2. 인증 및 규정 준수

– Complies with international certifications such as UL, CSA, 그리고 IEC, 글로벌 시장에 적합.

– Environmentally friendly design, free of hazardous substances like cadmium and lead.

선택 권장 사항
