Description
ZHC4931 – 4G RTU
ZHC4931 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.
- Support 1 relay output
- Supports 2 DI (dry/wet node) inputs
- Support 1 analog (current) input
- Supports 8 conditional control instructions, making control more convenient
- Provide 1 serial port (RS485/RS232)
- Support serial heartbeat package
- Supports multiple function codes: 01, 02, 03, 04, 05, 06, 0F, 10
- Support setting the direction of active data reporting
- Support TCP_Client, HTTP_Client
- Supports two working modes: host mode and slave mode. The host mode supports RS485 cascading of multiple Modbus devices.
