Изоляция: Withstands 5,000V between coil and contacts, and 10,000V surge voltage, complying with safety standards.

Параметры катушки

Диапазон напряжения: Доступно несколько вариантов, including DC5V, 12В, 24В, 48В, 100В, or AC12V, 24В, 100В, 200В.

Потребляемая мощность: Approximately 0.53W for DC type, and 0.9VA (at 60Hz) for AC type.

Рабочие характеристики: For DC coils, the pick-up voltage is ≤70% of the rated value, and the drop-out voltage is ≥15% of the rated value; for AC coils, the pick-up voltage is ≤80% of the rated value, and the drop-out voltage is ≥30% of the rated value.

Physical Design

Размеры: Approximately 29mm×13mm×29mm, weighing 20g, с компактным размером.

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

Среда: Operating temperature ranges from -40℃ to 70℃, humidity from 5% к 85%; resistant to vibration (10-55Гц) and shock (1,000м/с²).

Model Selection and Functional Differences

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

-С: Стандартный тип, no additional functions.

-СН: Встроенный индикатор работы. (ВЕЛ), supporting circuit status monitoring.

-СД: Built-in freewheeling diode, protecting the circuit from back EMF (electromotive force) влияние, suitable for inductive loads.

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

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

Например, 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. Сценарии применения

Промышленная автоматизация

– Controls actuators such as motors, электромагнитные клапаны, and contactors, supporting PLC system linkage.

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

Smart Home and Consumer Electronics

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

– Пример: 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.

New Energy and Power Systems

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

– Пример: Controls the on-off of charging circuits in электрический vehicle charging piles.

Medical and Transportation Equipment

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

Installation and Accessories
Sockets and Terminals

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

Меры предосторожности

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

– Во время установки, 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.
