Note: 1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method. 2. The response time is the time it takes for the main contact to open after the input is turned OFF. 3. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked. -
