In terms of application, plc uses microprocessor technology and communication technology, so it can be widely used in sequential control, motion control, communication, data management and other fields, and has extremely strong flexibility. However,...
A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specifi...
Choose DC relay or AC relay, many customers have a lot of confusion on their products. Customers often ask: My relay input is DC, and the output is AC; or the input I want is AC, and the output is DC; or DC to DC, AC to AC, will not work. Faced with ...
The reason why there is "what is the difference between relay control and contactor control" is because there are both similarities and differences between the two. The difference between the two is that they rely on controlling the on and off of sma...
If the relay does not light, it means that the relay may not work. Generally, the red light of the intermediate relay indicates AC voltage, and the green light indicates DC voltage. When it is found that the relay does not light, it is necessary to u...
Some automotive relays are designed with diodes or resistors built in. These devices help suppress coil voltage spikes and protect the electronic circuit. DIODE RELAY PROTECTIONWhen the voltage is removed and a relay is denergised the magnetic field ...
A latching relay, which is a subtype of electromechanical or electromagnetic switch, commonly chosen in scenarios where the operator needs to control (either switch off or amplify) a large amount of current flow. The key components in a magnetic or ...
Latching relays can be designed to operate using either a magnetic or a mechanical model. We’ve already touched on the fact that the core difference with latching relays, in comparison to other relay switch types, is their ability to hold and retain...
