Description

ZHC1931 is a device that supports 2 dry (wet) node detection, 1 relay (COM, NO) output, 1 analog. A network IO product with pseudo-quantity (current 4-20mA) detection and 2 serial ports transparent transmission, compatible with Modbus RTU/TCP protocol. With “remote control” as the core function, it is highly easy to use, and users can easily and quickly integrate into their own system to realize Remote and local control of Ethernet, RS485, RS232.ZHC1931 ZHC1931 ZHC1931 ZHC1931 ZHC1931 ZHC1931 ZHC1931 ZHC1931ZHC1931 ZHC1931 ZHC1931 ZHC1931ZHC1931 ZHC1931 ZHC1931 ZHC1931 ZHC1931ZHC1931ZHC1931ZHC1931
