Description
Parameter Specifications
- Power Supply: The RER133 typically operates on a 24V DC power supply. The power consumption is relatively low, around 8 – 12W, which makes it energy – efficient for long – term use in industrial applications.
- Input/Output Channels: It is equipped with 8 digital input channels and 8 digital output channels. The digital input channels can receive signals from various sensors such as proximity sensors, limit switches, and photoelectric sensors. The digital output channels are capable of controlling actuators like solenoid valves, relays, and indicator lights.
- Communication Interface: It features an RS – 485 communication interface, supporting the Modbus RTU protocol. This allows for easy connection to other devices in an industrial network, enabling data exchange and remote monitoring.
- Operating Temperature Range: Designed to function within a temperature range of – 10°C to 50°C. This range makes it suitable for a variety of industrial environments, including those with moderate temperature variations.
Applications
- Industrial Automation: In manufacturing plants, the RER133 can be used to control and monitor simple production processes. For example, it can control the movement of a small – scale conveyor system based on the signals from sensors detecting the presence of products.
- Agricultural Automation: In greenhouses, it can be used to monitor environmental parameters such as temperature and humidity through connected sensors and control ventilation fans or heaters accordingly.
- Building Automation: In small commercial buildings, it can be used for basic control tasks such as controlling the lighting system based on occupancy sensors or monitoring the status of door locks.
Weight and Dimensions
- Weight: Approximately 0.3 kg, which is relatively light and easy to handle during installation and maintenance.
- Dimensions: It has a compact design, with dimensions of about 100mm (length) x 80mm (width) x 30mm (height). This small size allows it to be easily installed in control boxes or other limited – space areas.
Features
- Cost – Effective Solution: The RER133 offers a cost – effective option for basic automation and control tasks, especially for small – scale applications where high – end features are not necessary.
- Easy Configuration: Configuration is straightforward. Users can set up input/output functions, communication parameters, and other settings through software or DIP switches, reducing the complexity of installation and operation.
- Modular Expandability: It has a modular design, which means additional units can be easily added to expand the input/output capacity as the system requirements grow.
Stability and Reliability
- Robust Construction: Built with high – quality components and a durable enclosure, it can withstand normal industrial vibrations, minor shocks, and dust.
- Electrical Isolation: It provides electrical isolation between input/output channels and the power supply, protecting the device from electrical interference and ensuring stable signal transmission.
- Long – term Testing: Through long – term testing, it has been proven to have a reliable performance over time, with a low failure rate.
Practical Case
In a small – scale furniture manufacturing workshop, the RER133 is used to control a simple wood – cutting machine. The digital input channels are connected to sensors that detect the position of the wood on the cutting table. When the wood reaches the appropriate position, the RER133 sends a signal through the digital output channel to activate the cutting blade. One day, there was a brief power surge in the workshop. Thanks to the electrical isolation feature of the RER133, the device continued to operate normally, and the wood – cutting process was not interrupted. The cost – effective and reliable performance of the RER133 ensured the smooth operation of the furniture manufacturing process.
