　　　　16. Supports Modbus RTU slave protocol

　　　　17. Multi channel indicator light

　　　　18. RS485 communication interface with lightning protection and electrostatic protection

　　　　19. Industrial machine temperature range to cope with harsh on-site environments

　　　　Application scenario: Built in DI acquisition circuit and relay adapted to monitor and collect various switch devices, control start/stop devices such as motors, pumps, access control, lighting, agriculture, etc

　　　　1、 Access control (controlling access control, monitoring access control switch status, electric doors, rolling shutter doors, gates, etc.)

　　　　2、 Valve monitoring (controlling the opening and closing of solenoid valves, monitoring switch status inquiry)

　　　　3、 Pump control (pump station control, real-time monitoring of pump unit operation status, motor start stop control)

　　　　4、 Lighting control (unmanned control of street lamps, stage lighting control, lighting control)

　　　　5、 Smart home (controlling the start and stop of household appliances such as air conditioning, access control, purifiers, and electric water heaters)

　　　　6、 Livestock farming (controlling exhaust fans, lighting, water supply, diet, etc.)

　　　　7、 Greenhouse (control door curtain motor, monitor temperature and humidity inside the greenhouse, control blower)

　　　　　　Provide parameter configuration software: The configuration software supports multiple configuration functions, allowing users to configure RTU parameters and functions according to their needs. It also supports script programming and personalized device management

　　　　　　Provide local control/testing software: a graphical interface provides DI collection feedback, DO remote control COM selection, baud rate, Modbus address settings, and other functions suitable for the application layer, meeting the simple needs of users

　　　　　　Communication between RTU and upper computer: Users can purchase a USB to 495 serial port adapter cable and use the RS485 serial port of the RTU to connect the adapter cable and convert it to USB, generating a COM port and easily establishing communication with the upper computer (or contact online customer service to purchase adapter cables from our company)

　　　　　　Provide secondary development manual technical support: provide device register addresses, detailed explanations of Modbus protocol, and 1-on-1 manual technical support guidance to facilitate users in quickly establishing project applications

　　　　　　Support DI and DO output linkage mode: While supporting switch quantity acquisition, switch linkage is also supported. Users can set the "high/low level trigger" and configure the trigger linkage operation "DO" for each DI channel. When the DI input triggers the "high/low level" value alarm, the DO output will immediately jump

　　　　　　Built in hardware level and software dual watchdog: automatic reset for abnormal situations, stable and reliable device without crashing. Hardware+software logic dog integration, when communication channel abnormalities occur, the logic dog will reset the system and restore normal operation

　　　　　　Embedded 32-bit ARM processor: high speed, high stability, low power consumption, coupled with software and hardware watchdog, the device never crashes

　　　　　　Provide Modbus protocol manual: Modbus RTU function code, detailed explanation of Modbus communication instance protocol, function code description, error code description and other development materials, and provide 1-on-1 manual technical support

　　　　　　Industrial grade long-life 2-year warranty, factory direct sales quality, after-sales guarantee: For any after-sales or warranty needs, please contact online customer service for quick handling

　　　　　　Provide technical assistance for project construction and renovation: The company has multiple departments including R&D department, technology department, project department, technical service production department, quality inspection department, etc., with strong R&D, production technology service, after-sales and other capabilities. It provides technical support services for various users in smart cities, smart factories, industrial 2.0 transformation, smart agriculture, smart power, smart artificial intelligence and other projects.
