What is the relay and the specific classification

Answer:

Chinese name: relay English name: relay Definition: An electrical appliance that causes a predetermined step change in the electrical output circuit when the input quantity (amount of excitation) changes to the specified requirement. What are the classification of the relay? Time Relay Static time relay | Time relay | AC power delay relay | DC power delay relay | High precision time relay | Transistor time relay | Intermediate relay Static intermediate relay | with intermediate relay | intermediate relay | delay intermediate relay | AC intermediate relay | fast intermediate relay | large-capacity intermediate relay | Large capacity relays RXMVB2 High Capacity Dual Position Relay DCS-10 High Capacity Dual Position Relay | RXMS1 Fast Trip Relay | RXSF1 Double Drop Signal Relay | RXMVB4 High Capacity Dual Position Relay |
