![]() After 56 years supplying surplus and new electronic parts and supplies, we have decided. MCP3008 Eight Channel 10-Bit A/D Converter with SPI The Microchip Technology Inc. ALL ELECTRONICS IS GOING OUT OF BUSINESS Clearance Sale in Progress. The inputs have a relay driver transistor and opto-isolator built-in which means the device needs 2. Prev: 12V to 3. MCP3008 - 8 Channel 10 Bit A/D Converter. These relays are fully 5V logic compatible. ![]() The main downside to relays is that being an electro-mechanical device, like any mechanical switch relays are more prone to wear and tear over prolonged use. They are also nicely contained little modules that are simple to hook-up and are especially useful for switching AC. Unlike transistors used for switching, relays use metallic switch contacts which avoids the power loss and heating inherent in transistor switching circuits. The following figure shows the relay module pinout. If it cant, youll have to get more clever and the solution isnt as simple as hooking up a opto-isolator. 5V 2-channel relay module 5V 1-channel relay module 5V 8-channel relay module 3.3V 1-channel relay module Relay Pinout. Check the specs for the 24 V signal and verify it can source the current computed in the previous step, with some margin. Relay modules are handy for controlling external loads. This is current you want to drive the input of the opto with. Can operate with opto-isolation or without it.LED indicators when relays are energized.Normally Open (NO) and Normally Closed (NC) contacts. ![]() KEY FEATURES OF RELAY MODULE 5V X 8 RELAY W/ OPTO-ISOLATION: Relay Module 5V x 8 Relay w/ Opto-isolation.If it is a pulse signal, please note that the limit of 817 is below 4KHZ, please do not use this module for control signals greater than 4KHZ, which will not work properly.The relay module has eight independent 5V logic compatible relays that control or up to each. Elegoo 8/4 Channel DC 5V Relay Module with Optocoupler Switching capacity available by 10A in spite of small size design for high-density P.C. This eight channel voltage converter module is extremely handy to convert 5 volt logic level signals. This item: Optocoupler Isolation Board, 24V To 3.3V 8-Channel Photoelectric Isolation Module Level Voltage Converter PNP Output PLC Signal 23.99 23. Item Type: Optocoupler Isolation BoardMaterial: PCBDriver Signal Voltage: 3.6-24VOutput Voltage Range: 3.6-30V (output current depends on the specific situation, but the maximum power is not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) 8 Channel Optocoupler Voltage Converter Module 3.6-30V. ![]() 3TURN ON CONTROLLED TERMINAL: Can realize 3.3V or 5V control interface of 3.6-24V voltage level, after the control terminal is turned on, the controlled terminal will also be turned on 4DRIVE VARIOUS OCCASION: Optical isolation has strong interference resistant ability, which can drive high power transistors, MOS tubes and other occasion that require high voltage drive, and can also directly drive low power 24V relays to work 5EXCELLENT PCB: Good quality PCB materials possess reliability and miniaturization, good maintenance and interchangeability 1HIGH LEVEL OR PULL DOWN OUTPUT: Whether the output terminal is high level output or pull down output can be realized through the jumper cap 2SIMULTANEOUS CONTROL DIFFERENT VOLTAGES: The 4 channels of 817 on the board are independent, which can realize simultaneous control of different voltages, etc. ![]()
