Lipstick Type 2 channels AI/AO/DI/DO 4G Remote Terminal Unit FCT-181222

This 4G network-connected control unit integrates 2-channel AI/AO (analog input/output), allowing for external sensor data acquisition via self-polling. It can be connected to a touchscreen for local control and display, and can be integrated with our company’s cloud platform for remote control. It has been widely applied in various intelligent transformation fields, such as factory power distribution box monitoring, intelligent control of agricultural greenhouses, smart street lighting projects, sewage treatment, aquaculture, and livestock farming, among hundreds of other industry applications. It supports connection to customer servers via TCP, MQTT, HTTP, and other protocols.

● 4G CAT.1 full network compatibility, strong signal, and low power consumption;

● Provides multiple configurations: 2-channel AI, 2-channel AO, 2-channel DI, 2-channel DO, etc., which can be used in pairs via a cloud server, one for AI/DI and the other for AO/DO.

● Digital I/O functions: Enables device status acquisition, local control, and inter-device linkage control.

● Analog I/O functions: 0-10V/4-20mA acquisition range is configurable.

● Server linkage: Enables input-output linkage and inter-device linkage.

● Edge computing: Supports digital and analog edge linkage for device output control, unaffected by network conditions.

● Customization services: Supports protocol customization, function customization, and hardware customization services.

● Provides software configuration for 4G parameters and status monitoring;

● Supports MQTT multi-topic subscription and publishing; supports MQTT transparent transmission and Modbus to JSON data packet conversion, and supports parsing JSON data from the server and scheduled reporting; supports MQTT protocol integration with various cloud platforms such as Huawei Cloud, Alibaba Cloud, and China Mobile Cloud;

● Superior lightning protection: Protects against lightning strikes, withstands induced high voltage, and prevents surges; fanless high-efficiency heat dissipation reduces repair time;

● Provides DIN 35mm rail mounting or wall-mounted installation; wide temperature range: operating temperature -40℃~ +85℃;
