Description

ZHC493C is a support2Road dry (wet) node detection,1Relay (COM, NO) output,1Analog quantity (current 4~20mA) detection, 1 channelRS485 pass through, 1 way RS232 transparent transmission The latest network IO products are 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 systems to realize LTE, RS485Remote and loca lcontrol.
