Earth Checker
Since it has an F-shaped relay design, it can be installed easily in a space-saving manner! It forms an alarm contact when it detects insulation failure.
We handle the "Earth Checker," which helps prevent failures by continuously monitoring the insulation resistance between the ground and the signal power supply and level crossing power supply as monitoring lines. The alarm contact configuration operation timing can correspond to each of the level crossing failure detectors N1, centralized automatic reset field devices, and electronic level crossing failure detectors. We conduct development design and manufacturing (prototype mass production) utilizing the technology of selecting LEDs and circuit board layout cultivated through railway signal and display devices. If you have requests like "I want an alarm like this" or "Can you make something like this with LEDs?" we are here to help, so please feel free to contact us. 【Features】 ■ When the insulation resistance of the monitoring line decreases and insulation failure is detected, an alarm contact is configured. ■ The F-type relay shape allows for space-saving and easy installation (the 5-circuit type is A-type relay shape). ■ The alarm contact configuration operation timing corresponds to each of the level crossing failure detectors N1, centralized automatic reset field devices, and electronic level crossing failure detectors. *For more details, please download the PDF or feel free to contact us.
