3. Communication Interface
   The VW3A3310D supports the Modbus RTU communication protocol over an RS – 485 interface. The communication speed can reach up to 9600 bps, allowing for efficient data exchange with other devices in an industrial network, such as Programmable Logic Controllers (PLCs), Human – Machine Interfaces (HMIs), and Supervisory Control and Data Acquisition (SCADA) systems.

Uses

1. Small – Scale Industrial Automation
   In small – scale manufacturing workshops, the VW3A3310D can be used to monitor and control simple production processes. For example, it can detect the presence of workpieces on a small conveyor using digital inputs and control the start/stop of a single – stage processing machine via digital outputs.
2. Building Automation in Local Areas
   In local areas of commercial buildings, like a small office or a single – floor area, it can manage basic building functions. It can be connected to door sensors and occupancy sensors to control the lighting or the operation of a single ventilation fan.
3. Agricultural Automation (Mini – Scale)
   In mini – scale agricultural facilities, such as a small greenhouse or a home garden irrigation system, it can monitor environmental parameters like the opening and closing status of small vents through connected sensors and control small – scale irrigation valves accordingly.

Weight and Dimensions

1. Weight
   The VW3A3310D weighs approximately 0.6 – 0.9 kg, which is relatively light, facilitating easy installation and handling.
2. Dimensions
   It has a compact design with dimensions around 110mm (length) x 90mm (width) x 35mm (height). This small size allows it to be installed in standard control cabinets or on DIN rails without taking up much space.

Actual Cases

1. Small – Scale Furniture Manufacturing
   In a small – scale furniture manufacturing workshop, the VW3A3310D was used to control a small cutting machine. It monitored the position of the wooden board on the workbench through a proximity sensor connected to the digital input. When the wooden board was in the correct position, the device sent a signal through the digital output to start the cutting process. This simple automation improved the efficiency and precision of the furniture production.
2. Small Office Lighting and Ventilation Control
   In a small office, the VW3A3310D was installed to control the lighting and ventilation. It was connected to an occupancy sensor and a temperature sensor. When an employee entered the office, the occupancy sensor sent a signal to the digital input, and the VW3A3310D turned on the lights via the digital output. When the temperature in the office exceeded a certain level, the temperature sensor sent a signal, and the device turned on the ventilation fan, creating a comfortable working environment.
