2.Control equipment
3.Ethernet Output interface
4.Input interface
5.Controlled terminal
6.Local control terminal
Remote Control
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 man power and material resources. 
Modbus protocol adaptation:
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.
Support Master mode and Slave mode for user to choose:
Default work mode of USR-IO424T is Slave mode and IO424T can be queried and controlled by Master device in Network side and RS485 side simultaneously in Salve mode. IO424T 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.

3.RS485 anti-surge protection: 2KV
4.Over-current protection for power supply
EFT:
When there is instantaneous high current in the circuit(such as power switch, etc.), it can ensure that the device hardware is not damaged.
Power supply interface ±4KV
Ethernet interface and serial port ±2KV
ESD:
Prevent electrostatic damage equipment(Such as: dust electrostatic, electric arc, etc.)
Air ±15KV
Contact ±8KV
Watchdog:
Well-designe
d hardware watchdog which can realize 24 hours stable operation.
Work mode:
Master mode
In master mode, after IO424T receiving data, it will judge destination address firstly. If destination address is local address, IO424T will process data; if destination address isn't local address, IO424T will forward data. In this mode, user can connect to multiple slave devices by RS485 cascading connection.
Slave mode
In this mode, IO424T can connect to master device or work as single device. In this mode, IO424T will analyse and process received data. If destination address is local address, IO424T will make a corresponding reaction; if destination address isn't local address, IO424T will discard data.
Features:
Conditional control
Conditional control function supports user configuring the conditions to trigger IO changes. It can make using IO424T 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 IO424T or powering on IO424T 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.
Support analog acquisition and temperature acquisition
Analog acquisition adopts public reference ground method to connect, that's to say it can convert to voltage detection; temperature acquisition can acquire temperature status by PT1003 line.
USR Cloud function
Industrial agreement: Modbus protocol devices can quickly access to USR Cloud
Historical data: curve and report forms.
Alarm push: WeChat, e-mail and message.
Open API: provide SDK and Demo source code.
Applications:
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.
Temperature and humidity monitoring of agricultural greenhouse
User can connect IO424T to remote server to monitor and control greenhouse status such as: temperature and humidity, soil temperature and humidity, etc. This solution can realize starting or stopping by IO424T's remote control function to realize automated management of smart agriculture. 
Smart lamp control
 User can connect to USR Cloud by USR-IO424T 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.
Smart hotel management
In smart hotel management project, user can connect USR-IO424T 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 output interface to multiple Relays and connect input interface to switching value, then connect USR-IO424T 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-IO424T's output Relays to realize remote control of powering on/off. USR-IO424T's RS485 interface can connect to RS485 electricity meter to realize remote charging, remote control, etc.
