General Purpose Relay DPST-NO (2 Form A) 24VDC Coil Through Hole
Active

Overview

The G2RL-2A4-DC24 is a low-profile power relay featuring a DPST-NO (2 Form A) contact configuration and a 24VDC coil. Designed for through-hole mounting, this fully sealed relay offers a compact footprint with a height of only 15.7mm, making it suitable for dense PCB layouts. It is a general-purpose component capable of handling high-power switching tasks in industrial and consumer electronics.

Why Choose This Part

The fully sealed construction allows for automatic soldering and cleaning processes while protecting contacts in harsh environments. With a low coil current of 16.7 mA and high dielectric strength, it provides an efficient and safe interface between low-power control logic and high-power AC/DC loads.

Applications

HVAC Control Systems
Switching heating elements, fans, and compressors in climate control units where high isolation is required.
Industrial Automation
Used in PLC output modules and control circuits to drive actuators and motor starters.
Smart Home Appliances
Integrating power switching for washing machines, refrigerators, and smart lighting hubs.
Power Distribution Units
Managing dual-circuit switching in networked PDUs or UPS systems.

Getting Started

When designing with this relay, ensure a flyback diode is placed across the 24VDC coil to protect driving transistors from inductive spikes. Verify that PCB trace widths for the DPST contacts are sufficient for the intended load current to prevent thermal issues. Refer to the manufacturer footprint for the 5mm pitch through-hole layout.
