- Introduction of MQTT Modem
ZHC493C is a network IO product which support 2-channel dry (wet) node detection, 1-channel relay (COM, NO, NC) Output, 1 channel analog quantity (current 4~20mA) detection, 1 channel RS485/232 transparent, 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, RS485/232.
Product model: ZHC493C, the network is 4G full Netcom, providing 1RS485/1RS232/2DO/1DI/1AI interface
Featured functions: automatic collection, scheduled restart, and the device itself supports logic operations.
Protocol: Support JSON protocol acquisition control, Modbusr RTU/TCP.
Industrial-grade quality: anti-reverse connection, anti-surge, dual watchdogs, can work normally at -20℃~+60℃,
Application: remote power meter power-off control, vending machine, smart street light automatic switch.
ZHC493C supports obtaining SIM card number, signal strength, setting APN, reading and writing positioning information.
ZHC492C supports setting 8 logics.
Forward follow: DI is closed and DO is closed
Reverse follow: DI is closed and DO is opened, DI is opened and DO is closed
Greater than or equal to: trigger DO output when AI input is greater than or equal to the set value
Less than or equal to: trigger DO output when AI input is less than or equal to the set value
ZHC493C can quickly transmit data collected by various sensors to facilitate server summary and analysis, so as to realize real-time monitoring of data and promote the development of agricultural Internet of Things.
The basic function of ZHC493C is to realize the two-way transparent transmission through RS232/485 to 4G, support 4G, industrial design, built-in hardware watchdog protection, Has high speed, low delay characteristics.
| ZHC493C supports "arrival at the set time point (Beijing time), trigger an action" |
| Item | Properties | Parameters |
| Mode | Whether to turn on this timing trigger | Enable/Disable |
| Timing time | The time point when the action is triggered | Hour: 00~23; Minute: 00~59; Second: 00~60 |
| Action type | Type of action performed | Restart/DO |
| Execution channel | When the action type is DO, the output channel of DO | DO1~4 |
| Execution state | When the action type is DO, the DO channel outputs a value | on/off |
