Frequently Asked Questions
Q: What is the difference between the G5V-2 and G5V-2-H1 relay models?
A: The standard G5V-2 series supports a 2A contact current rating and is available in 5V, 12V, and 24V coil voltages. The G5V-2-H1 series has a 1A contact current rating and extends to a 48VDC coil voltage option, making it suitable for higher-voltage coil drive applications where lower contact loads are acceptable.
Q: Are these relays compatible with standard PCB relay sockets?
A: Yes. The G5V-2 series uses a standard 8-pin DIP through-hole footprint (20.5mm × 10.1mm × 11.5mm), making it compatible with widely available PCB relay sockets and direct PCB soldering setups.
Q: Can I use these miniature signal relays with a microcontroller like an Arduino?
A: The 5VDC coil variants are well-suited for use with Arduino and similar 5V microcontrollers, typically via a transistor driver circuit or a dedicated relay module board, since the relay coil may draw more current than a GPIO pin can supply directly.
Q: What does DPDT (2NO + 2NC) mean on this relay?
A: DPDT stands for Double Pole Double Throw. This relay has two independent switching poles, each with a Normally Open (NO) and a Normally Closed (NC) contact. This allows you to simultaneously switch two separate circuits when the relay coil is energized.
