8ch RS485 Simple PLC IO Expanding Board Multifunction Delay Relay Module for RasPi RPI Raspberry Pi Pico Python C++(with Shell)

Packing list: 1PCS (select the version you need)Product Features:Operating voltage: DC 7~25VOperating Current : Standby current (Digital tube OFF) 15MA, Standby current 34MA (Digital tube ON), 1 relay open 68MA, 2 relays open 100MA, 3 relays open 126MA, 4 relays open 157MA,5 relays open 179MA, 6 relays open 204MA, 7 relays open 250MA, 8 relays open 283MAOn-board resources: 1x RS485 Interface 8x opto-isolated inputs (low level trigger, NPN type), 4x buttons, 1x 4 bit digital tube display, 1x PI PICO slots, 8x relay outputsSize 153*72*19mm(Only Board)Weight : 157g(Only Board), 267g(with shell)As long as you write MicroPython code(sketch),You can use it to achieve a variety of delay timer function,such as:RS485 Master-Slave Device(PLC MCU)Motor forward and reverse,Timing on,Timing off,Power-up delay,Trigger delay,Infinite loop delay,A finite number of cyclic delays,Power sequencer,And so on.We provide the code(sketch) can only achieve a simple delay function,The delay time is adjusted by modifying the delay parameter of the code(sketch).If you need more functionality, write your own code. We do not provide additional code(sketch) and technical supporthow to use: See video ''DN33C08 DEMO''(You can search for videos on GOOGLE)Note:DN33C08 is an expansion Module for Raspberry Pi Pico board, it cannot work independently.If you do not have a Pi Pico board, Please purchase the Module ''Board for Pi Pico''Application 1: Through the programming of Pi Pico Board, various delay customization functions can be realized instead of PLC.Application 2: It can be used as an RS485 master device instead of PLC/PC/touch screen to control various RS485 slave devices.
