Intermediate relay mainly plays a role of signal transmission and transformation in the circuit, it can implement multiple control, and small power control signal can be converted to the large capacity of contact action, to drive the www.dongfeng-motor.com electric actuators. Intermediate relay contacts, can expand other electrical control function. Choose intermediate relay, mainly on the basis of the control circuit voltage grade, should also consider the number of contact, type and capacity to meet the requirements of the control circuit. Commonly used in machine tool in the rotor and stator middle of the relay type has diesel generator set two kinds of JZ7 series, JZ8 series. JZ8 for ac/dc relay. The selection of time relay. Time relay is one of the line is commonly used in electrical machine control. Its types are: electromagnetic, air damping type, electric and electronic etc. Application more is the air damping type time relay. small diesel engine alternator generator Its characteristic is reliable, simple structure, time delay setting range wider (up to 0.4 ~ 180 s). The models have JS7 - A, JS16 series. Tao, the choice of a time relay mainly considering control system circuit electric generator delay contact way of the delay, delay range and the www.facebook.com/guohong.trading generator number of the instantaneous contact, but also pay attention ac motors to the coil voltage grade can meet the requirements of control circuit.
