KJT speed control switch products are mainly developed according to the actual needs of customer sites. The products have a wide range of electricity, and can be applied to 24VDC─110VAC─220VAC (different voltage levels are configured with intermediate relays of different voltages), bringing unified purchasing to users. Easy installation and good interchangeability. The product can effectively and timely handle electrical and process failures such as stalling, jamming, overloading, slow rotation, belt slipping, transmission chain (belt) falling off, transmission shaft breakage, etc. that often occur in motors and mechanical transmission devices. It can play a role in ensuring production and maintaining equipment.

• It is strictly prohibited to connect the intermediate relay directly to the 220V power supply, if the product is damaged due to direct connection to the 220V power supply, it is considered "man-made damage" and is not covered by the free warranty.

• If installed on a metal base, please pay special attention to the distance of H1 in order to prevent the equipment from starting due to the strong interference of magnetic materials.

• The installation distance of H2 should be about 4mm to prevent the change of H2 caused by external reasons.

• When installing the RD-II in the open air, please install a rain cover as much as possible to prolong the service life of the product.

• The jump-off time is marked on the product box and the product case.
