ZHC492C – 4G Modbus RTU

Description

ZHC492C is a support 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) Output, 4 channels of analog quantity (current 4~20mA) detection, 1 channel RS485 transparent network IO products, compatible with Modbus RTU/TCP protocol. With “remote control” as the core function, it is highly easy to use, users can easily and quickly integrate into their own systems to realize remote and local control based on LTE, RS485.
