ZHL4931

ZHC1931 is a network IO product that supports 2 channels of dry (wet) node detection, 1 channel of relay (COM, NO, NC) output, 1 channel of analog quantity (current 4~20mA) detection, and 1 channel of serial port transparent transmission. It is compatible with Modbus RTU /TCP protocol. With “remote control” as the core function and high ease of use, users can easily and quickly integrate it into their own systems to achieve remote control based on LTE network. Remote control over LTE networks.
