Since it has an F-shaped relay design, it can be installed in a space-saving manner! It forms an alarm contact when it detects insulation failure.

We offer an "Earth Checker" that 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 and 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 LED selection and circuit board layout cultivated through railway signal and display devices. We can solve your problems such as "I want this kind of alarm" or "Can’t we make something like this with LEDs?" so please feel free to contact us. 【Features】 ■ When the insulation resistance of the monitoring line decreases and insulation failure is detected, the alarm contact is configured. ■ The F-type relay shape allows for space-saving and easy installation (the 5-circuit type uses an A-type relay shape). ■ The alarm contact configuration and operation timing can correspond 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.
