ETROB02 ETROA01 FAQ
https://eletechsup.com/products/dc-12v-24v-1-2ch-din35-rail-rs485-ethernet-modbus-rtu-relay-board?variant=46538862690461 I have a question for you: *Can I control the relay simultaneously using Ethernet and RS485 (at the same time, sometimes sending commands to the relay via Ethernet, and sometimes via RS485)? Can I simultaneously control the relay using the Ethernet connector and the RS485 connector? My assumptions: Program number 1 on the computer is connected to relay number 1 via the Ethernet connector. Program number 2 on the computer is connected to relay number 1 via the RS485 connector. Program number 1 and program number 2 are running simultaneously on the computer. The signal to open the relay can be sent by either program number 1 or program number 2. Can the ETROB02 2DI-2DO work in this way? Answer : Yes. Ethernet and RS485 can work at the same time.

ES32C14 FAQ
Hi, I buy the shield for esp32 (photo). But I connect Signal 4-20 ma, but the resistence that I see is for 90 ohms. The input in pins 34-35, etc.. has a suport Max range 3,3 v. But I get input 24 v dc (4-20ma), the Max Volts is 1,86 v. The resolution ADC is 11 bits. The great resistence mabe would be 165 ohms. Could you help me, if you have another Shield? I have a Big proyect. Thanks. Answer : Sorry! We don't have other expansion boards. But you can replace the resistors yourself.

ET69C02 FAQ
ET69C02 , Hi, we have a lot of your network modules connected to your relay modules. we have encountered an issue. The network modules loose their connection to the network. They start working fine after setup but in time just loose connection and there is not ping to them and no web interface, until you restart the network module, and sometimes even have to reset the module. We have tried to increase the voltage to 12.9-13.0 volts, but it did not work. This is our general configuration: Answer : 1 The power supply may be disturbed. Please use an independent DC 12V power supply 2 The network interface may be disturbed. Please change the network cable environment 3 If the problem still cannot be solved, please replace the ET69C02 board.
