The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method. *2. Not including bounce time. *3. The response time is the time it takes for the main contact to open after the input is turned OFF. Includes bounce time. *4. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked. *5. The durability is for an ambient temperature of 15 to 35C and an ambient humidity of 25% to 75%. *6. Weight shown is for 24-VAC/VDC type. For 100 to 240 VAC type, add approximately 20 g. i Applications g9SA-th301 (24 VDc) with 2-hand inputs Timing Chart S11 (NC) S11 (NO) S12 (NC) Feedback loop S12 (NO) KM1 and KM2 (NC) KM1 and KM2 (NO) 0.5 s max.
