- Q:Thermal relay
- Protect the main circuit current does not exceed the set value. For example: 3KW motor can use the set value of 6A thermal relay, the protection of the motor will not be burned for a long time overload.
- Q:C61F-GP CKC water level relay 1.E3 is input common? 2. Is E1 E2 at the same time there is an electrical input water level relay coil to pull? still is?
- Seeking automatic manual level control wiring diagram
- Q:Inductive proximity switch three-wire NPN normally open how to control 24V relay
- Three-wire NPN proximity switch, if it is working power 24V DC. among them A line connected to the work of the positive power, usually brown, received 24V power positive There is a negative power supply is connected to the negative, generally blue, received 24V power supply negative
- 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 are three-phase phase of the input and output, L1.L2.L3. For the input. T1.T2.T3 for the output, of course, some are not the subject, roughly. 4 contacts are normally open and normally closed. The upper and lower corresponds to a group of NC is normally open, NO is normally closed. There should also be an adjustable knob, according to the actual transfer of the current. If a similar electrical problems Can go to QQ group discussion: 36760239 electric group
- Q:Relay HRS4H-S-DC5V pin of the five pins were how to connect? Or have this forum recommend it
- As shown in the figure, the number of the five pins of the relay HRS4H-S-DC5V pin is clockwise at pin 1, 2, 3, 4 and 5, respectively. Of which 2,5 is the normally closed contact pin; 2, 4 is the normally open contact pin; 1, 3 is the coil pin.
- Q:For convenience, the above figure. Relay Model: JZX-22F / 2Z with light. First ask this thing is the relay or contactor? Can it be used I would like to use PLC (Siemens s7-300 (cpu314c-2pn / dp)) simple control motor start and stop. Ask three-phase power into the line A / B / C were connected with the relay, and then U / V / W and how to connect that a few points? After programming 13,14 terminal with PLC which several terminals connected? I do not know what I asked right, but hope you can definitely answer me, thank you. There is I want to give the switch signal can not be sent to the PLC through the host computer, plc signal sent to the relay after the implementation? I look forward to your answer
- You are the middle of the relay, 13 14 is the relay coil ah, the relay coil is AC220 then 13 then PLC output, 14 then N line, FireWire access PLC COM side, with the relay to open the open contactor Of the coil, ABC UVW are connected to the AC contactor on the main contact
- Q:One is a thermostat is a solid state relay used to control the heating pipe, how should the connection
- Temperature control table 3-4 ends, and solid-state relay corresponding to 3-4 points connected to one end of the heating pipe directly connected with the zero line. The other end of the heat pipe is connected to the solid state relay 1. Solid state relay 2 is connected with FireWire; Temperature control table solid state is the current industrial automation control common control circuit, is the general circuit engineers must be familiar with; All manufacturers of temperature control table control solid state relay labeling methods are the same. SSR is the solid state relay control output.
- Q:The role of the relay
- The relay is an electronic control device, it has a control system (also known as the input circuit) and the control system (also known as the output circuit), usually used in automatic control circuit, it is actually a small current to control the larger A "automatic switch" of the current. So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.
- Q:What is the maximum allowable maximum current for a solid-state relay?
- Solid-state relay secondary side generally optocoupler isolation primary, voltage control, only the maximum allowable voltage at all, generally 32VDC, the current consumption will not exceed 15mA. If it is a side of the output current, according to the use of thyristor capacity and cooling different, the current maximum size I have seen single-phase 600A 380V, but not actually used.
- Q:I use the electronic circuit control 24V relay, with 24V relay control high-power contactor, I would like to ask the general 24V relay coil power
- there is a very simple way to calculate the relay power: first with a multimeter to measure the relay [coil resistance], and then divided by 24v [coil resistance], get the [relay operating current], then take 24v multiplied by [ Relay operating current], is the relay work when the actual power consumption.
