Industrial-grade anti-interference design, suitable for the electromagnetic environment of small workshops and equipment sites

Convenient installation and maintenance: Compact DIN rail installation, no rack required, saving control cabinet space; The status indicator light intuitively reflects the working status and fault type. The program supports online download, making debugging and maintenance simple and efficient

Limited expansion flexibility: Supports the connection of 2 Q series expansion modules. Analog quantity modules, high-speed counting modules, etc. can be added as needed to meet the functional expansion requirements of small-scale systems (such as adding temperature collection and high-speed positioning functions).

Application scenarios

Single-machine automation equipment: Single-machine control of small injection molding machines, sealing machines, labeling machines, and ultrasonic cleaning machines. Through built-in I/O drive solenoid valves, contactors, and indicator lights, it realizes equipment start and stop, sequential actions, and simple process control (such as single-point regulation of temperature and pressure).

Small-scale production line control: Logical control of electronic component insertion lines, small-scale assembly lines, and manual auxiliary production lines, achieving multi-station linkage, counting and sorting, fault alarm functions, and controlling a small number of actuators and sensors

General mechanical auxiliary control: Auxiliary action control of small machine tools (fixture clamping, coolant switch, workpiece conveying), start/stop and protection control of fans/pump sets, speed regulation and zonal control of small conveyor lines

Small-scale automatic control for buildings and infrastructure: Lighting zone control for small office buildings and computer rooms, air conditioning fan coil control, and automatic start and stop of water supply and drainage pump sets. Communication with local touch screens via Modbus TCP is achieved to realize simple centralized monitoring
