I would like a board designed that can control 4 solid state relays, 120vac at 6-10 amps. It must be able to detect 4 ac inputs. It must be able to count on 4 pins 12-24vdc. With pin protection, ie opto, diode, and resister circuit. Also must have a 485 interface. The 120vac circuits should have switches to manually override logic.

Hello , How are you ? Hope all is fine ! Regarding your project , I have worked on many control projects that utilized opto-isolated mechanical relays and the more advanced SSR. I design the boards with multiple power domains (logic , Relays , load) . you can see samples of my work on my portfolio and my youtube channel. =============================================================================== =============================================================================== I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. I also have long experience with PCB design. I have worked with low-speed , high-speed and power boards. I use Altium Designer and Eagle, and I deliver neat layout that conforms to your dimension constraints and the manufacturing constraints. More to be discussed once you contact me . BR, M.T.

Hi, I'm interested in your project. I've designed a board similar to this using a dsPic to read 10 ADC channels and output 10 DAC outputs. If you could provide me more details on the design such what is the logic to handle the sold state relays and other specifications such the input to read, logic, etc. I will be able to provide a logic bid amount. Thanks

Hello, I am interested to design this board for you. I can design board (schematic, layout and prototype) with pic controller and other required parts. I would suggest breaking project in several steps - confirming circuit schematic and components, making layout and finally making prototype PCB with all components for testing. Most expensive parts will be adequate solid state relays, most likely on heatsink with screw terminals for connecting load. For 12-24vdc counting inputs isolated optocouplers will be used and RS485 IC for half-duplex RS-485 connection. I am not quite sure what you mean by "It must be able to detect 4 ac inputs". Do you need microcontroller to detect if there is AC voltage connected to solid state relay? Best regards and let me know any questions.

Previously I did one project related to your concept. So, based on AC supply voltage I am controlling Led Display board (VMS).
