Key Features
- SPST-NO contact configuration rated for 16 A at 250 VAC, enabling direct switching of mains-voltage resistive loads from a 5 VDC control signal
- High-reliability (HR) design with reinforced insulation between coil and contacts, exceeding standard PCB relay safety requirements
- 5 VDC coil operation at 80 mA enabling direct drive from microcontroller output stages with a small transistor or relay driver IC
Applications
The G5RL-1A-E-HR-DC5 is used in home appliance control boards, industrial automation panels, and smart energy meters where a 5 VDC logic signal must switch AC mains loads up to 16 A. Its high-reliability construction and reinforced insulation make it suitable for safety-critical PCB relay positions in HVAC controllers, washing machines, and programmable logic controllers.

Frequently Asked Questions
What load current and voltage can the G5RL-1A-E-HR-DC5 relay switch?
The G5RL-1A-E-HR-DC5 can switch up to 16 A at 250 VAC for resistive loads, making it suitable for directly controlling heaters, motors, and lighting circuits from a PCB. Its SPST-NO contact configuration provides a normally open switching path that closes when the 5 VDC coil is energized.
How does the high-reliability (HR) rating of G5RL-1A-E-HR-DC5 benefit safety-critical designs?
The HR designation indicates reinforced dielectric insulation between the 5 VDC coil circuit and the 250 VAC contact circuit, providing higher creepage and clearance distances than standard relays. This meets stricter safety standards for appliances and industrial equipment, reducing the risk of insulation breakdown in harsh environments with humidity or voltage spikes.
Can a standard 5 V microcontroller GPIO directly drive the G5RL-1A-E-HR-DC5 coil?
The relay requires 80 mA of coil current at 5 VDC, which exceeds the typical 20 mA GPIO drive capability of most microcontrollers. A small NPN transistor (e.g., 2N2222) or a dedicated relay driver IC is needed between the GPIO output and the coil, along with a flyback diode to suppress the inductive voltage spike when the coil is de-energized.
