What is G5RL-1A-E-HR-5DC used for?
The G5RL-1A-E-HR-5DC is widely used in home appliance control boards to switch AC heating elements, motors, and lighting loads rated up to 16 A at 250 VAC from low-voltage MCU control signals. HVAC systems deploy it as a fan contactor or compressor starter relay driven by a 5 V microcontroller output through a small NPN transistor. Industrial equipment designers also specify it for programmable logic controller (PLC) output modules where a compact, high-current SPST relay is required to switch field devices across isolated AC power rails.

Frequently Asked Questions
What is the maximum contact current and voltage rating of the G5RL-1A-E-HR-5DC for switching AC loads?
The G5RL-1A-E-HR-5DC is rated for 16 A at 250 VAC for resistive loads, which corresponds to up to 4000 VA of switched power — sufficient for household heating elements, motor starters up to 1 HP, and lighting circuits. For inductive loads such as motors, the rated switching capacity is derated to approximately 8 A at 250 VAC due to the higher peak inrush current during motor start cycles.
How much coil current does the G5RL-1A-E-HR-5DC draw at 5 VDC and can a typical MCU GPIO pin drive it directly?
The G5RL-1A-E-HR-5DC requires approximately 70 mA to 90 mA of coil current at 5 VDC, which far exceeds the typical 8 mA to 20 mA source capability of a standard MCU GPIO pin. A small NPN transistor such as the 2N2222 or BC547 with a 1 kΩ base resistor is recommended between the MCU output and the relay coil, with a freewheeling diode across the coil terminals to suppress the inductive back-EMF spike up to 50 V that occurs when the relay is de-energized.
How long does the G5RL-1A-E-HR-5DC last in a high-cycle industrial application, and what does the HR designation indicate?
The G5RL-1A-E-HR-5DC carries Omron's HR (High Reliability) designation, which specifies a rated mechanical life of 100,000 operations without load and an electrical life of 10,000 operations at rated 16 A / 250 VAC resistive load. At a typical industrial cycle rate of 10 operations per hour, the electrical life equates to approximately 1000 hours of operation. For higher-frequency switching such as thermostat control cycling multiple times per hour, a solid-state relay should be considered after 1000 operating hours to avoid contact wear.
Is the G5RL-1A-E-HR-5DC a suitable drop-in replacement for the Omron G5RL-1-E-5DC in a home appliance control board?
The G5RL-1A-E-HR-5DC is functionally similar to the G5RL-1-E-5DC, sharing the same SPST-NO configuration, 5 VDC coil, 16 A / 250 VAC contact rating, and PCB footprint. The key difference is the HR (High Reliability) suffix on the 1A-E variant, which doubles the rated mechanical cycle life from 50,000 to 100,000 operations and adds stricter quality screening. The HR version is a direct pin-for-pin replacement with improved longevity, making it the preferred choice for appliance designs targeting 10-year service life requirements.
