Overview

The G2R-2-DC12 is a power relay designed for PCB mounting, featuring a DPDT (2 Form C) contact configuration. It operates with a 12V DC coil and is capable of switching loads up to 5A, making it a versatile choice for power management in embedded systems.

Why Choose This Part

The G2R series offers a compact footprint with high dielectric strength of 5000V between coil and contacts. Its DPDT configuration allows for simultaneous switching of two independent circuits, which is ideal for reversing motor polarity or managing dual-line power safety.

Applications

HVAC Controls
Switching fan motors and valve actuators in climate control systems.
Industrial Automation
Interfacing low-power PLC outputs with high-power industrial actuators or contactors.
Smart Home Appliances
Controlling power to heating elements or motors in consumer white goods.
Power Distribution Units
Providing isolated switching for individual outlets in networked PDU designs.

Getting Started

When integrating this relay, ensure the driving circuit can sink the 43.6mA coil current, typically requiring a BJT or MOSFET driver with a flyback diode. Designers should follow the recommended PCB hole patterns to maintain safety creepage and clearance distances between the high-voltage load and low-voltage control traces.
