FAQ

What is the maximum switching current for the ABR-1S418B?

The ABR-1S418B has a conventional free air thermal current (Ith) of 5 Amperes. It is designed for switching control signals and small loads, not for high-power applications.

Yes, the 24V DC circuit for this relay module includes built-in protection against reverse polarity, which prevents damage to the component during incorrect wiring.

While it offers standard functionality, a direct replacement depends on the specific terminal layout, physical dimensions (11mm width), and electrical ratings. Always verify the datasheet of the relay you are replacing to ensure full compatibility before installation.
