Q:Relay on the MC, NO there COM mean what?: COM - Common, refers to the common, according to whether the power, can be with the NC side or NO side contact

Q:The relay is connected to the diode: Since the coil of the relay is the original of the inductive current, the coil will generate self-induced electromotive force when the current flows through the coil. According to Faraday's law, the magnitude of the self-inductance electromotive force is proportional to the rate of change of the current through the coil (coil flux change rate). So when the power off instantaneous current rate of change is very large, the coil will produce higher than the power supply voltage several times the self-inductance electromotive force and superposition with the power supply voltage (self-inductance electromotive force can be determined according to Leng's law). If the relay coil ends without diodes, such a high voltage on the circuit will damage the circuit on the transistor and other original devices. So we are connected at both ends of the coil and connected to the diode, and the power of the coil generated by the self-induced electromotive force polarity to meet the two positive conduction conduction to form a continuous flow, the self-induced current discharge to protect the circuit Transistor and other original devices. This is the role of relay diode.

Q:What is the relay contact and dynamic contact: Moving contact, also known as "normally open contact", is the relay coil in the absence of electric pull when the contact in the open position. The contact is closed after the relay is energized; Dynamic contact, also known as "normally closed contact", is the relay coil in the absence of electric pull when the contact in the closed position. The contact opens after the relay is energized.

Q:Drive a 24V intermediate relay how much current ah: There are many kinds of intermediate relays, the current is also very small.

Q:Loss of power delay time relay, power delay time relay, respectively, how the role, please point: Power loss delay time relay: When the time relay is energized, the normally closed delay contact immediately becomes open, and the normally open delay contact real-time turns on; when the time relay is de-energized, it starts to reset to the set time reset ( Often open the original state). Power delay time relay: When the time relay is energized, it will turn on. When the time relay is turned off, it will return to normal time. Original state).

Q:OMRON PLC with computer software programming time relay and counter how to compile: WR (Work Register) on behalf of the auxiliary relay, PLC program used as an intermediate relay, because the writing method is different from I: 10.00,500.00, etc., can facilitate the management of the program and readability, a see this W register Know what it is pre-arranged for their own use.

Q:The work of the car relay, such as five-pin relay they are what the role of each line of the details of the details of the more detailed the more grateful: First, the negative pole of the second investment into the money. Three main power supply. Four Dian Dian appliances. Five positioning or other linkage electrical appliances.

Q:What is the difference between the application of the relay KA and the KM?: 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. The KM contactor is used to turn on and off the load. It is combined with a thermal overload relay to protect the electrical equipment in operation. It is combined with the relay control circuit, remote control or interlock related electrical equipment. AC contactor: The typical structure is divided into double breakpoint direct drive (LC1-D / F *) and single break (LC1-B *). The former is compact, small size, light weight; the latter easy to maintain, easy to configure the unipolar, secondary and multi-pole structure, but the volume and installation area. DC contactor: its action principle and AC contactor similar, but the DC breakdown of the magnetic load stored in the magnetic field instantaneous release, breakpoint generated by high-energy arc, so the DC contactor has a certain arc function.

Q:What is the difference between the intermediate relay and the AC contactor: That popular point is The intermediate relay controls the small flow of the AC contactor to control the flow

Q:Plc relay why soft relay: Because the relay in the PLC is not visible outside, change the control does not need to re-wiring, as long as the re-programming just fine!
