A: No. The coil is rated for 12V nominal. Using it with 24V will immediately burn the coil. Look for the G8B-241-01 (24V coil variant).
You cannot drive this relay directly from a microcontroller (like an Arduino or PIC) because the coil requires more current than a logic pin can supply, and the coil voltage (12V) is higher than logic voltage (3.3V/5V).

The Omron G8B-201-01 is a specialized automotive relay primarily recognized for its role as an OEM (Original Equipment Manufacturer) turn signal flasher unit for various vintage and modern Honda motorcycles. While it is a relatively small component, it is vital for the safe operation of a vehicle's signaling system. Overview of the Omron G8B-201-01
The G8B-201-01 is a 12V DC flasher relay manufactured by Omron, a leader in electronic components. In the automotive world, it is often cross-referenced with the Honda part number 38301-MF8-771.
This relay is designed to control the rhythmic flashing of turn signals. It is often housed in a protective rubber mount to shield it from the vibrations inherent in motorcycle operation. Key Specifications
While specific datasheets for discontinued or legacy OEM-only parts like the G8B-201-01 can be rare, its primary characteristics align with standard automotive relay standards: Operating Voltage: 12V DC.
Terminals: Typically features a 3-pin configuration ("mini faston" style) used for input, output, and ground.
Manufacturer: Omron, specifically for Honda's motorcycle division. omron g8b-201-01
Interchangeability: It is often considered interchangeable with other flasher units like the Mitsuba FR-3303. Common Vehicle Applications
The Omron G8B-201-01 was a staple in many Honda motorcycles from the 1980s through the early 2000s. Owners of the following models frequently seek this specific relay for repairs:
Honda VF series: Such as the 1985 VF1100S Sabre and V65 Magna.
Honda Shadow series: Including the Shadow Spirit 750 (2001–2007).
Honda CBR series: Notably the CBR 600 F4 and various Hornet models.
Honda Scooters: Like the Honda Pantheon 125/150 (1998–2002) and Silverwing. Symptoms of a Failing Relay
If you are troubleshooting your motorcycle's electrical system, a faulty G8B-201-01 relay usually manifests in a few specific ways:
Non-responsive signals: The turn signals do not light up at all when the switch is engaged.
Solid lights: The signals turn on but stay illuminated without flashing.
Irregular flashing: The signals flash much faster or slower than usual (often a sign of a load mismatch or internal component failure). Sourcing and Availability
Because this is an older OEM part, you will most likely find the Omron G8B-201-01 through specialty parts retailers or second-hand marketplaces:
Used/OEM Surplus: Retailers like Hooprider Parts often stock tested, used units for vintage restorations. A: No
Online Marketplaces: eBay is a reliable source for both new-old-stock and pulled parts from salvaged bikes.
Modern Alternatives: Some riders replace this relay with modern LED-compatible flashers if they have upgraded their incandescent bulbs to LEDs, as the original G8B-201-01 is designed for standard bulb resistance. Honda Omron Turn Signal Flasher Relay G8b-201-01 - eBay
A very specific request!
The Omron G8B-201-01 is a power relay, so I'll try to craft an interesting story around it. Here's a tale:
The Mysterious Case of the Unreliable Elevator
In the heart of Tokyo, there was a sleek, modern skyscraper that housed a prominent electronics company. The building's elevator system was designed to be efficient and reliable, but lately, it had been malfunctioning. People would press the button, and sometimes, it would work; other times, it wouldn't.
The maintenance team was stumped. They checked the usual suspects: the control panels, the motors, and the wiring. Everything seemed fine. That's when they called in the expert, a brilliant engineer named Yui.
Yui examined the elevator's control system and discovered that the issue lay with a small, but critical component: a power relay. Specifically, the Omron G8B-201-01.
The relay was supposed to switch the elevator's motor on and off, but it was malfunctioning. Yui suspected that the problem was due to a faulty coil or a worn-out contact. She decided to replace the relay with a new one.
As she was about to install the replacement, she noticed something peculiar. The faulty relay had a small inscription on its side: "For Elevator 3 Only." Yui wondered if this was a clue.
She investigated further and discovered that the building's previous engineer had designed a custom system for Elevator 3. The Omron G8B-201-01 relay was part of a secret "shortcut" circuit that allowed the elevator to bypass the regular control system. The inscription was a warning to anyone who might replace the relay: "Use with caution."
Yui realized that the malfunctioning relay was not just a simple failure; it was a symptom of a clever hack. The previous engineer had created a hidden "express lane" for Elevator 3, which allowed it to move quickly and efficiently, but also caused the occasional glitch. Basic Wiring Steps:
With this new understanding, Yui replaced the relay with a standard one and adjusted the control system to eliminate the shortcut. The elevator began working smoothly, and the building's occupants were relieved.
From then on, Yui made sure to inspect all the relays in the building, including the Omron G8B-201-01. She realized that even the smallest components could hold big secrets and that understanding their role was crucial to keeping the systems running smoothly.
And that's the story of how the Omron G8B-201-01 relay helped Yui unravel the mystery of the unreliable elevator!
