Product Description

Serial To 2G IOT Cellular Modem With 4DO 4DI 4AI Ports For remote Control

 

  • Introduction​ of IOT Cellular Modem
  •  

 

ZHC2921 is a network IO product that supports 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) output, 4-channel analog (current 4~20mA) detection, and 1-way serial port passthrough transmission. It is compatible with Modbus RTU/TCP protocol.With the function of "remote control" as the core, it is highly easy to use, and users can easily and quickly integrate into their own system to realize the remote control based on GPRS network.
