3. Physical Design

Dimensiones: Approximately 29mm×13mm×29mm, weighing 20g, con un tamaño compacto.

Montaje: Plug-in terminals (p.ej., P2RFZ-08E socket), supporting PCB or DIN rail mounting, reducing wiring time by 60%.

Ambiente: Operating temperature ranges from -40℃ to 70℃, humidity from 5% a 85%; resistant to vibration (10-55Hz) and shock (1,000m/s²).

1. Model Selection and Functional Differences

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

-S: Tipo estándar, no additional functions.

-SN: Luz indicadora de funcionamiento incorporada (CONDUJO), supporting circuit status monitoring.

-DAKOTA DEL SUR: Diodo de rueda libre incorporado, protecting the circuit from back EMF (electromotive force) impacto, suitable for inductive loads.

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

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

Por ejemplo, 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. Escenarios de aplicación

1. Automatización Industrial

– Controls actuators such as motors, válvulas solenoides, 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.

– Ejemplo: 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.

– Ejemplo: Controls the on-off of charging circuits in eléctrico vehicle charging piles.

4. Medical and Transportation Equipment

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

1. Installation and Accessories
2. Sockets and Terminals

– It is recommended to use Push-In Plus sockets such as P2RFZ-08mi, 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. Precauciones

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

– Durante la instalación, ensure that the contact load does not exceed the rated value; para cargas inductivas, a diode or RC snubber circuit must be used in conjunction.

1. Procurement and Alternative Solutions
2. Supply and Price
