1. Application scope
The JX10, JX20, JX30 series static signal relays are composed of discrete components and small relays. This product has a fast action speed and overcomes the defect of the original electromagnetic signal relay being unable to respond to the action indication signal due to the use of a fast acting vacuum switch in the domestic power system's tripping and closing circuit. It has manual and electric reset functions and can well meet the requirements of unmanned duty rooms. It has multiple sets of dynamic closing contacts and can meet the requirements of signal indication and remote transmission. It has strong shock resistance and can be installed freely, with a wide current action
Advantages such as specifications and scope. The products are divided into JX-10, JX-20, JX-30, which can be updated to replace DX-11/11A, DX-8/8G, DXM-2A, DX-30 and other products.
