Elevator relay is what type of relay, to be sophisticated and efficient DC12V, through 2A, 220VAC, this is the use of ordinary magnetic retention relay?
Yes. This is not a high tech. Can guarantee the number of actions and reliability on it. The manufacturers are the same. The general majority of Omron. Where is the market? Just because it is reliable. Of course, you can also look at the pure import to do the price comparison.
Do you need a magnetic relay? Should not need it
I recommend Hongfa relay, domestic products are also very good, Omron really not recommended.
Intermediate relay for elevator.
?
Intermediate relay: used in relay protection and automatic control system to increase the number and capacity of contacts. It is used to pass the intermediate signal in the control circuit. The structure and principle of the intermediate relay are basically the same as those of the AC contactor. The main difference from the contactor is that the main contact of the contactor can pass through the high current and the contact of the intermediate relay can only pass through the small current. Therefore, it can only be used in the control circuit. It is generally no main contact, because the overload capacity is relatively small. So it is all with auxiliary contacts, the number of more. The new national standard for the definition of intermediate relay is K, the old national standard is KA. Usually DC power supply. A few use AC power.
