Product Description

GPRS 3G 3G IOT Cellular Modem Modbus RTU M2M IO Controller With Antenna

 

  • 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.
