Tianjin SENTINEL Electronics Co., Ltd. was established in 2008, initially focusing on the R&D and manufacturing of sensors and fieldbus devices. In 2019, the company embraced the trend of intelligent manufacturing and launched a new IO-Link product line, opening a new chapter in intelligent connectivity technology.

With the rapid development of IO-Link technology, after five years of continuous research and technical accumulation, the substation devices have become very mature. This article will introduce several representative IO-Link substation products, showcasing their applications and advantages in the field of industrial automation.

Background and Advantages of IO-Link Technology

IO-Link is an open standard point-to-point communication protocol that provides efficient device interconnection and intelligent data transmission solutions for the industrial automation field. It not only transmits data but also enables real-time monitoring of device status and diagnostic information, improving overall system efficiency. The core advantages of IO-Link lie in simplifying device integration, optimizing production processes, and supporting predictive maintenance through real-time data, thereby reducing unexpected downtime.

Maturity and Diversified Selection of Substation Devices

Over the past five years, SENTINEL Electronics has launched various series of IO-Link substation devices to meet the needs of different industrial applications. These substation products mainly consist of the IP20 and IP67 series, designed for different environments and requirements, and they excel in I/O point integration, environmental adaptability, and installation flexibility.

IP20 Series: Integrated High-Density I/O Points

The IP20 series substation devices are products designed by the company for industrial scenarios requiring high-density I/O points, suitable for relatively clean environments such as indoor equipment cabinets. This series integrates 32 I/O points and supports multiple flexible configurations, allowing users to choose from the following combinations based on actual needs:

• 32 inputs
   
• 32 outputs
   
• 16 inputs + 16 outputs

This design allows the IP20 series products to flexibly adapt to various automation needs, providing an efficient connection and control solution, especially in scenarios where precise control of numerous sensors and actuators is required during production processes.

Application Scenarios:

The IP20 series is particularly suitable for installation in environments that require high-density I/O integration, such as automated production lines and equipment control cabinets. For example, in the manufacturing of electronic components or precision assembly industries, this high-density configuration can effectively improve equipment operating efficiency and reduce wiring complexity.

IP67 Series: Adaptation to Various Harsh Field Environments

The IP67 series substation devices offer higher environmental adaptability, particularly suitable for outdoor or harsh industrial environments. With an IP67 protection rating, these devices can operate stably in environments with high humidity and dust. The IP67 series also provides a variety of specifications and interface types, mainly in M8 and M12 interface specifications, allowing users to choose according to actual usage needs.

M8 Specifications: Compact Design for Limited Space

The M8 specification substation module is compact, designed for space-constrained installation scenarios, offering the following configurations:

• 8 inputs
   
• 8 outputs
   
• 16 inputs

The 8-output configuration also offers Class A and Class B IO-Link interfaces, allowing users to flexibly configure based on the characteristics of different devices. The compact design makes the M8 series very suitable for situations where multi-point control is needed, but space is limited.

M12 Specifications: Powerful and Flexible Configuration

Compared to M8, the M12 substation modules offer more flexibility and scalability, meeting the control needs of large equipment or complex systems. The M12 series provides the following I/O configurations:

1. Switch Input/Output Modules:
    
   • 16 inputs
      
   • 16 outputs
      
   • 8 inputs + 8 outputs
      
   • 8 inputs + 4 high-current outputs (up to 2A per point)
      
   • 8 high-current outputs (up to 2A per point)
      
2. Analog Input Modules:
    
   • 8 4~20mA/0~20mA input modules
      
   • 8 0~10V input modules

The design of the M12 series provides users with more diverse choices, allowing them to flexibly respond to different application scenarios. The switch modules are suitable for switch control applications that require a large number of I/O points, while the analog modules cater to precise signal measurement needs, especially for sensor data collection and monitoring.

Application Scenarios:

The IP67 series substation is particularly suitable for harsh industrial environments, such as outdoor automated equipment and areas with high humidity or dust on production lines. The M8 specification is widely used in compact automated systems, while the M12 specification is suitable for complex industrial systems requiring high current output or signal processing, such as automated machinery and logistics handling systems.
