1. Optocoupler Isolator

2. Bestol 100pcs PC817 PC 817 SOP-4 SMD Optocoupler

3. Cylewet 30Pcs Optocoupler PC817C 2.54mm Pitch 4 Pins DIP-4 Mounting Photo Coupler

• Optocoupler output type: optical transistor
• Pin pitch: 2.54mm
• Number of pin: 4
• Isolation voltage: 5kv

4. Optocoupler Isolation Board, Signal Converter Module Voltage Level Translator Current Voltage

• 4>. high voltage test, current amplification.
• 5>. excellent service, if you have any questions after purchase, you can contact us and we will handle it for you as soon as possible.
• 3>. can be used in the inverter to invert the output signal.
• 1. the scm output level can be used to isolate, resist interference and protect certain circuits of the scm while driving the motor.
• 2>. the scm output level is low and the drive module voltage is high.

5. Icstation 24V to 5V 8 Channel Optocoupler Isolation Board Voltage Level Translator PNP

• This is an 8 channel one-way transmission digital signal converter. it can convert pnp signal to npn. support max conversion frequency 20khz.
• Attention: the dc power supply is the same as the signal output voltage. for example, if the signal is 3.3v to 5v, then vcc = 5v input.
• It is also a dc 24v to 5v voltage level converter board. support mcu/plc signal level converting.
• Each channel equipped with an led indicator, make it easier to recognize their working status.
• Please feel free to contact us if you have any question about the product. we provide replacement if you get a defective unit.

6. 5V Relay Module with Optocoupler Isolation Support High and Low Level Trigger Relay

• "high", "low" level controllable - with a jumper cap, you can choose a low level control or a high level control, allowing the relay module to adapt to more occasions.
• Adopts smd optocoupler isolation - use two sets of fully isolated power supply system power, to ensure that the relay in the switch will have an impact on the signal circuit and can be freely switched to high level drive mode or low level drive mode. trigger current is 5ma.
• It has a fault-tolerant design - even if the control line is broken, the relay won't actuation.
• High quality module - the relay module uses genuine high-quality relays. the maximum load of the frequently opened interface is: ac 250v/10a, dc 30v/10a.
• User-friendly interface design - all interfaces can be directly connected through the terminal block, which is very convenient

7. ICStation 1CH DC 3V 3.3V Relay Power Switch Module with Optocoupler High Level

• Use the classical and beautiful black pcb and metal components, looks cool and pleasure to the eyes, which will show your whole diy project superior. 2pcs with the independent anti-static packing. size: 50x26x17mm/1.97x1.02x0.67inch, voltage: 3v-3.3v, current: <200ma (operating), <5ma (trigger). operating temperature: -25~85 celsius.
• Load capacity7a, 240v ac, 10a 120v ac, 10a 28v dc. please do not go beyond the voltage or current, or it will burn the relay contact. load wire is fenestrate processed, if it is tin plated, it can bear high current (please pay attention to the insulation).
• Icstation 1ch 3v 3.3v relay power switch module with optocoupler high level trigger for esp8266 development board. optocoupler isolationit can control high current load via low current, and replace mechanical switch.
• Interface input: vcc, gnd, in, load port: normal close, common, normal open. wiringvcc connects dc 3.3v positive, (2) gnd connects dc 3.3v negative, (3) in connects main control equipment input port, such as mcu, sensor output port (0 and 1, you can adjust via the switch on your own), (4) please note that the power cannot be reversely connected, or it will burn ...
• Connect the power, when push the switch to l, in port will input low level, and relay will operate, s lamp will be on. if com and no are connected, when input high level, the relay will release, and s lamp will be off. if com and no are disconnected, it becomes connection between com and nc. if push the switch to h, and not use the relay, nc and com are connected.

8. NOYITO PC817 4-Channel Optocoupler Isolation Board Voltage Converter Adapter Module 3.6-30V Driver

• Photoelectric isolation has strong anti-interference ability. it can drive high-power triodes, mos tubes and other applications that require high-voltage driving, and can also directly drive low-power 24v relays.if it is a pulse signal, please note that the limit of 817 is 4khz or less. if the control signal is greater than 4khz, please do not use this module, it will n...
• This module is used when it comes to the need for isolation control and voltage conversion.
• Drive terminal signal voltage: 3.6-24v. output terminal voltage range: 3.6-30v (output current depends on the specific situation but the maximum does not exceed 10ma, the total power is constant, the voltage and current are inversely proportional)
• Important noteplease choose "brand of noyito " and "fulfilled by amazon", we have not authorized other sellers to sell this product.
• It can realize 3.3v or 5v to control the interface of 3.6-30v voltage . after the control terminal is turned on, the controlled terminal will also be turned on.
