![]() ![]() Here are some instructions on how to use it with our DC Motor Driver. However, if you want to do more advanced things (like combining it with a quadrature encoder and doing edge-triggered interrupts) then you will want to use an opto isolator to keep things nice and clean. Using multiple Opto-Isolator Boards with digital expansion addressing, up to 128 input modules and 1024 output modules can be connected to one Data Acquisition. In normal operation, this is not a problem. I have modified the code for the ports I need and have managed to select 8 pins that can be used. Both the input side and the output side are designed to interface with equipment using logic voltages of anywhere from 3.3V to 24V. Step 1: COMPONENTS IN THE DESIGN The front end of the design consists of the PIC WEB OLIMEX board seen here with the ethernet cable connected and the Pickit 3 connected. The DC motor driver can generate a bit of line noise. General Description This product provides four channels of optical isolation with both a non-inverting output and an inverting output for each channel. Attach the corresponding outputs to device B The Opto-Isolator Mini Board is a small compact solution to a problem, that is becoming increasingly common with the new low power consumption 3V microcontrollers available on the market now. PC817 4 Channel Optocoupler Isolation Board I/O isolation for MCUs (Micro Controller Units) Noise suppression in switching circuits Signal transmission.Attach up to 4 output signals on device A to the 4 IN inputs.The basic technique is this (with device A (sender) and device B receiver) General Description This product provides four channels of optical isolation with both a non-inverting output and an inverting output for each channel. ![]() The device is intended to isolate the circuits electrically, so each side needs to be powered independently. : NOYITO PC817 4-Channel Optocoupler Isolation Board Voltage Converter Adapter Module 3. Additionally, you will need to properly hook it up to each devices power supply. Since it just passes signals through it, you just hook it up between the two different devices you want to communicate. They're keyed, so they can only be inserted in one orientation. ![]()
