<b>Relay is an electrical control device that usually used in automatic control circuit. The relay in fact is an automatic switch which uses a smaller current to control a larger current. In the circuit, it functions as automatic adjustment, security protection and conversion circuit.<b/><br> <b>Specification:<b/><br> Contact Capacity: <br> Normal switching Capacity (Resistance load): <br> -NO (Normal Open) 40A 14VDC <br> -NC (Normal Closed) 30A 14VDC <br> Max. switching current: 40A <br> Max. switching voltage: 30VDC <br> Max. switching power: 560W <br> Performance Parameter:<br> Endurance (operations): <br> -Mechanical (at 10,800 ops./h): 10,000,000 <br> -Electrical (at 900 ops./h): 100,000 <br> Ambient Temperature: -40°C +125°C (no condensation) <br>
