Overall and installation dimension(mm):
- Q: What is relay?
- A relay is an electronic control device that is usually used in an automatic control circuit and is actually an "automatic switch" that uses a smaller current to control a larger current. So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.
- Q: In the main circuit, the fuse and thermal relay thermal components can be less with one or two? Both the fuse and the thermal relay can only use one of them can play a short circuit and overload protection? why?
- Thermal relay as an overload protection of the motor is necessary to be installed.
- Q: What is the difference between optocoupler thyristors and solid state relays?
- SCR optocoupler is optocoupler to increase the characteristics of thyristor made of digital control equipment: Control terminal voltage is low, low current, used for digital system control, with optical isolation, with optocoupler high isolation voltage characteristics. After the control terminal is connected, the rear stage is turned on, and the rear stage is not cut off when the current flows in the latter stage until the controlled terminal current stops resuming until it receives the next preceding signal and has the same characteristics as the thyristor. Solid state relays are power devices: The control terminal voltage is higher, the current is relatively large, and more for the simulation system control, non-contact electronic switch, the isolation voltage is relatively low. After the end of the circuit connected to the post-level, after the closure of the pre-class circuit closed. In use, the same parameters can be common, but the thyristor generally smaller package, solid state relay larger.
- Q: OMRON relay G9EA-1 PDF data there Electrical endurance (See note 6.): 400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min. And now do not understand what this means! Look under the detailed instructions There is trouble to recommend a relay can be placed on the PCB board Requires electric shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge instantaneous current is about 1200A away Trouble to recommend a relay can be placed on the PCB board Requires shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge current is about 1200A
- Ops / min. Ops is the abbreviation for Operations, which means the maximum number of switches (or actions) per minute, but some kind of relay will have its life, that is, how many times it can switch, for example, thousands of times. 400 VDC is the maximum voltage of the coil. 30A is the maximum switching current number The other you have to choose according to the equipment sample manual.
- Q: What is the speed relay working principle?
- Speed relay, as the name suggests, is when the machine running to a certain speed, you can make the relay action. Commonly used speed relay there are two, one is mechanical, directly to the machine or motor speed to take to promote the contact of the clutch. The JMP speed relay, which can reflect the level of the machine or motor speed out to promote the contact of the clutch, and the Hall sensor is similar.
- Q: What is the role of thermal relay what is it?
- Thermal relay is controlled by the temperature of the switch off the relay, the role is to use low-voltage circuit on the off to control the high-voltage circuit off
- Q: The left side of the 6 input and output contacts on the right there are 4 input and output contacts have any use
- 6 contacts connected to the main circuit, 4 contacts control circuit
- Q: Is there a DC thermal relay?
- Our synchronous motor DC zero excitation undercurrent protection is used in this model. You can specifically check the next, you need the JL14 overcurrent relay model.
- Q: I would like to ask: PLC output sub-relay output and thyristor output, what is the difference.I only control the general digital signal, what type should be selected?
- 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: Components: 24V power supply 1 24V motor 1 24V relay 1 (2 normally open 2 normally closed) Button 1 trip switch 2 Purpose: press the start button to achieve positive and negative reversal, only use a 24V relay (with two relays everyone will) Hope that a master can figure, thank you!
- Travel switch a lot of categories, you can search on Baidu or Taobao search directly to a lot of pictures. Simply the equivalent of touch-type keys, will be released after the release
