8-way GSM/GPRS network IO controller
After powering network IO controller, user can directly realize remote control by USR Cloud. Take lamp control as example: user can realize lamp control by PC or APP on mobile terminal, and user can also directly open/close lamp by local switch. Remote control can realize all-weather and all-sided monitoring, save the cost of manpower and material resources.
Can automatically identify Modbus RTU/TCP protocol in network side and respond data according to received protocol to realize response data as same format as received data.
Default work mode of USR-IO808 is Slave mode and IO808 can be queried and controlled by Master device in Network side and RS485 side simultaneously in Salve mode. IO808 can also be configured into Master mode and Master mode supports connecting to multiple Modbus RTU devices by RS485 cascading connection. Master mode is suited to remote monitoring and control such as temperature and humidity monitoring of agricultural greenhouse.
Well-designed hardware watchdog which can realize 24 hours stable operation.
In master mode, after IO808 receiving data, it will judge destination address firstly. If destination address is local address, IO808 will process data; if destination address isn’t local address, IO808 will forward data. In this mode, user can connect to multiple slave devices by RS485 cascading connection.
In this mode, IO808 can connect to master device or work as single device. In this mode, IO808 will analyse and process received data. If destination address is local address, IO808 will make a corresponding reaction; if destination address isn’t local address, IO808 will discard data.
Conditional control function supports user configuring the conditions to trigger IO changes. It can make using IO808 more flexibly and extend application scenario. User only needs to modify conditional control function register parameters, it will realize corresponding function. Conditional control function can provide convenience for project management.
Support configuring IO status hold
After restarting IO808 or powering on IO808 again, can choose holding the Relay output status or resetting to disconnect status.
Support upgrading firmware by FTP
Support upgrading firmware by FTP: can remotely upgrade firmware by Modbus commands.
EWR version supports Router function
EWR version supports multiple functions such as LAN control, Ethernet, WiFi, Web Server, etc.
Combine configuration software solution
Network IO controller can connect to devices that needs to be monitored by input interface, output interface and RS485 cascading connection. Then can choose local connection or USR Cloud remote monitoring, convert network data to serial data by VCOM software and transmit to configuration software to realize remote monitoring and control. Commonly be used in unmanned machine room, integrated management of hotel facilities, self-service supermarket, etc.
Smart lamp control
User can connect to USR Cloud by USR-IO808 to realize remote street lamp monitoring and it is convenient to control in Cloud side and record the devices status. Whole solution can ensure overall rate of lighting of street lamp, help management and bring the benefit of environmental protection.
Industrial automation solution
In production-line item of industrial automation, it can realize production line monitoring and control by USR-IO808. For example, user can monitor production line quantity by infrared radiation switch or connect output interface to motor to control start and stop.
Smart hotel management
In smart hotel management project, user can connect USR-IO808 to TV, computer, refrigerator, air conditioner, door control system, etc. Then user can realize remote monitoring by mobile terminal. This solution is usually realized through local WiFi connection and it can also use USR Cloud to realize remote monitoring.
Self-service terminals solution
Based on remote monitoring function of USR-IO424T, user can connect Based on remote monitoring function of USR-IO808, user can connect output interface to multiple Relays and connect input interface to switching value, then connect USR-IO808 to Cloud platform to realize monitoring running condition of self-service terminals, adjusting supply chain at any time or handling failure timely.
Distribution box solution
Control AC contactor or breaker by USR-IO808’s output Relays to realize remote control of powering on/off. USR-IO808’s RS485 interface can connect to RS485 electricity meter to realize remote charging, remote control, etc.
