Hi, I have a problem with one of my setups. H32B and input panel stops communicating after 6-10 tries.
After deset it is ok gor 6-10 tries and then stops.

We changed the input panel and it is the same problem. Communicating with Home assistant and mode red is working, Just the connection with panel and contoller.
H32B was not replaced.

Any suggestions?

Hi
I am designing a pressure controlled vacuum tank.
Software of ESP32 and
Nextion screen is OK

But I have problem when
I get digital input from (TMCB)
thermal magnetic circuit protector( schneider gv2me14)
When red fault contacts close I want to get information of fault of motor.  But esp32 reset itself .

32- ModBus Adapter Protocol

In some 3rd-party applications the terms "PNP" / "NPN" are used to describe the polarity of the control signal (whether positive +12V or ground 0V voltage is used as the control signal). The KC868-H32BS outputs +12V (or +24V) per each output channel to control the relay. If a relay module is used, it gets a 0V as a common control line and +12V signal per each channel. Is this configuration considered as "PNP" or "NPN" connection from the point of view of the relay module?

improvement:

1. add MQTT topic include "post password" function. Improved security for controller

   

2. add 8 channel sensor input ports for effective pulse width options. Such as a sensor trigger signal time, from 10ms ---1 second.

Hello! 

I installed KC868-H32B with our mqtt server.

Sometimes TCP Client Led(white color) is blinking. what is that mean? 

thank you!
