Q:How long is the relay from power to suction?
: Different products have parameters that are generally in the tens of milliseconds or so it
Q:How the intermediate relay is self-locking
Self-locking relay principle is the coil power through the switch after the suction, the auxiliary contact at the same time connected to provide the coil of the pull power, switch off after the relay self-locking
Q:There is a fuse, why should the thermal relay
Fuses and thermal relays can play the role of "overload protection". Once the fuse in the fuse is selected, the performance of the overload is fixed. The thermal relay set the temperature can be adjusted, more convenient.
Q:Why solid state relays are solid
You know the electromagnetic relay has a contact, the coil is energized after the contact action to make the circuit connected, so it is operating state, and solid-state circuit breaker is no contact, the use of thyristor as a switch, when the control voltage signal On the conduction, and no contact action, which has a relay function, not a relay, so give it a solid circuit breaker name, and electromagnetic relays to be distinguished.
Q:What is TTL-> relay
Is the TTL level signal control relay. Is a kind of control relay. Control relay is an automatic electrical appliances, it is suitable for long-distance connection and breaking off, DC small capacity control circuit, and in the electric drive system for control, protection and signal conversion. The input of the control relay is usually the current, voltage and other electricity, it can be temperature, pressure, speed and other non-power, the output is the contact action when the electrical signal or output circuit parameters change. Relay is characterized by a change in its input to a certain program, the output will be a step change.
Q:The difference between the relay output and the thyristor output
The key question depends on what kind of control is your load required 1, the relay output can be used for DC, AC control of the switch control due to the total number of life So the output frequency is too high too high the total number of life will soon finish 100,000 times as the total number of technological progress may be higher 2, the transistor is generally used for occasions with fast frequency changes for DC power on and off control High frequency must be transistor output And can not be followed by contact type of intermediate relay
Q:What is the working principle of thermal relays?
Q:DC motor forward and reverse diagram of a relay
As shown in the figure, where the trip switch a choice of moving open, a choice of moving off, pay attention to the trip switch and motor steering related, can not be anti Turn left to turn right
Q:In the main circuit, the fuse and thermal relay thermal components can be less with one or two?
Thermal relay as an overload protection of the motor is necessary to be installed.
Q:Is there a DC thermal relay?
JLl4 series AC and DC current relay (hereinafter referred to as relay), suitable for AC 50Hz voltage 380V and below, DC voltage 220V and below the control circuit as overcurrent or under current protection purposes.
