ESP32 S3 Industrial IoT Controller RS485 Module 4-20mA Input N8R2 N8R8 N16R8 MOS Switch for PLC Automation

ESS3A22 is an ESP32-S3 expansion box with rich expansion ports. It uses pluggable terminals with a spacing of 3.81MM, which makes it easy to plug and unplug wiring. It uses a fully enclosed shell and can be used as a smart home host after the code is developed.Product Features:1 Operating voltage: Wide voltage DC 7-30V2 Operating Current : Standby current 25MA, 1 relay ON 55MA, 2 relays ON 85MA, 3 relays ON 115MA, 4 relays ON 145MA,5 relays ON 175MA,6 relays ON 215MA3 Size 150*132*40mm4 Weight : 297gOnboard Resources4CH 0/4-20MA Current Input4CH 0-5V/10V Voltage Input8CH NPN Digital Input6CH 10A Relay Output4CH 3A MOS Output9CH Free Port1CH RS485 BUS1CH KEY1CH LEDLoad current description:Relay Load current: DC 1-24V <7A;24-30V <5A,30-110V <3AMOS Load current: DC 3.3-4.5V <2A; DC 4.5-8V <4A;DC 8-24V <5A;Reminder:1 Although ESS3A22 has a fully enclosed shell, it is recommended to remove the shell to develop the code during the development stage, and then cover the shell after the development is completed2 Although the board has an ''ESP32 S3 N8R2'' core board, it is still recommended that you prepare an ESP32 S3 core board so that you can replace the board at any time when the core board fails.As long as you write ESP32 code,You can use it to achieve a variety of delay timer function,such as:WIFI Remote control switchWIFI Current and voltage collectionRS485 Master-Slave Device(PLC MCU),4x 0/4-20MA Current Collection,4x 0-5V/10V Voltage Collection,8x 3.3-24V NPN Digital sensor acquisition6x 85-265V Home appliance control4x 5-30V LED dimming, or low-power motor speed regulationMQTT,HTTP,WEB Remote control switchMotor 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.This is an expansion board based on 44PIN ESP32-S3. We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.If you need more functionality, write your own code. We do not provide additional code and technical supportNote:The ESS3A22 expansion board only supports the ESP32 S3 core board with a width of 44PIN and 28MM. The expansion board comes with an ESP32 S3 core board, but the ESP32 S3 board is more easily damaged during the development process, so it is recommended to prepare your own ESP32 S3 core board.
