SE3008

Description

Parameter Specifications

1. Power Supply
   The SE3008 typically operates on a 24V DC power supply. The power consumption is relatively low, around 8 – 12W, ensuring energy – efficient operation for long – term use in industrial and other relevant settings.
2. Input/Output Channels
   • Digital Inputs: It is equipped with 8 digital input channels. These inputs are designed to interface with common digital sensors such as proximity sensors, limit switches, and photoelectric sensors. The input voltage range is 18 – 30V DC, which is compatible with a wide variety of industrial sensors.
   • Digital Outputs: There are 8 digital output channels. Each output channel can handle a resistive load of up to 1.5A and an inductive load of up to 0.8A. This allows it to control devices like relays, solenoid valves, and small – sized motors.
3. Communication Interface
   The SE3008 supports the Modbus RTU communication protocol over an RS – 485 interface. The communication speed can reach up to 9600 bps, enabling 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 SE3008 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 SE3008 weighs approximately 0.7 – 1 kg, which is relatively light, facilitating easy installation and handling.
2. Dimensions
   It has a compact design with dimensions around 120mm (length) x 100mm (width) x 40mm (height). This small size allows it to be installed in standard control cabinets or on DIN rails without taking up much space.

Characteristics

1. Cost – Effective Solution
   The SE3008 offers an affordable option for small – scale automation projects. It provides essential input/output and communication capabilities at a reasonable price.
2. Easy Configuration
   The device can be easily configured using simple software tools. Users can set up input/output parameters, communication settings, and diagnostic functions without complex programming knowledge.
3. Electrical Isolation
   It features electrical isolation between input/output channels and the power supply. This helps prevent electrical interference and protects the device and connected equipment from damage.

Stability and Reliability

1. Robust Construction
   The SE3008 has a durable housing that can withstand normal industrial vibrations, dust, and moderate temperature variations.
2. Fault Protection
   It is equipped with over – current and over – voltage protection circuits. These safeguard the device from electrical faults, ensuring reliable operation over time.
3. Long – Term Testing
   The device has undergone long – term testing under various operating conditions to verify its stability and reliability, giving users confidence in its performance.

Actual Cases

1. Small – Scale Plastic Molding Workshop
   In a small – scale plastic molding workshop, the SE3008 was used to control a small injection – molding machine. It monitored the position of the mold through a proximity sensor connected to the digital input. When the mold was in the correct position, the device sent a signal through the digital output to start the injection process. This simple automation improved the efficiency and quality of the plastic product manufacturing.
2. Small Office Lighting and Fan Control
   In a small office, the SE3008 was installed to control the lighting and a single ventilation fan. It was connected to an occupancy sensor. When an employee entered the office, the occupancy sensor sent a signal to the digital input, and the SE3008 turned on the lights and the fan via the digital outputs. When the office was unoccupied, the lights and the fan were turned off, resulting in energy savings.
