Product Overview
When reliable Modbus Plus communication is critical in your Modicon Momentum automation platform, the Schneider 172PNN21022 Modbus Plus Adapter Module provides a compact and efficient solution. This adapter module serves as a single-port communication interface, ensuring seamless data exchange in industrial control systems.
Technical Specifications Breakdown
The 172PNN21022 operates on a rated supply voltage of 5 V DC, with a tolerance of +/- 5%. Its current consumption ranges from 200 to 350 milliamperes at 24 V DC, ensuring efficient power usage. The module features a 9-pin D-shell connector for Modbus Plus connectivity and includes one LED for communication status indication. With IP20 protection and conformal coating, it is suited for controlled environments. The operating temperature range is 0 to 60°C, and storage temperature spans -40 to 85°C, both in non-condensing conditions. Operating altitude is limited to less than 6,561 feet (2,000 meters). The module includes a lithium battery with an approximate lifespan of 5 years.
Industry Applications
In manufacturing environments, the 172PNN21022 enables reliable Modbus Plus communication between PLCs and remote I/O modules. For example, in a packaging line, this adapter module ensures consistent data transfer for real-time monitoring and control. Its compact dimensions (25 mm height, 143.1 mm width, 60.06 mm depth) and lightweight design (85.05 g) make it easy to integrate into existing cabinets.
Installation & Setup Guidance
Mount the 172PNN21022 on a standard Modicon Momentum I/O base. Connect the 9-pin D-shell connector to the Modbus Plus network using a suitable cable. Ensure the supply voltage is within the specified 5 V DC tolerance. Verify that the communication LED illuminates to confirm proper operation. For optimal performance, install the module in a location with ambient temperatures between 0 and 60°C and relative humidity between 5 and 95% without condensation.
Maintenance & Reliability
The lithium battery in the 172PNN21022 has a lifespan of approximately 5 years. When the battery low indication occurs, the module retains data for less than 30 days at 40°C. Regularly inspect the module for dust accumulation and ensure the IP20 enclosure remains intact. The conformal coating protects against moisture and contaminants, enhancing long-term reliability.
Compatibility & Integration
This adapter module is designed for the Modicon Momentum automation platform and supports the Modbus Plus communication protocol. It integrates seamlessly with Schneider Electric PLCs and other Modbus Plus-compatible devices. The single-port configuration simplifies network topology in point-to-point or multi-drop applications.
Selection Guide & Purchasing Advice
Before ordering the 172PNN21022, verify that your system requires a Modbus Plus adapter module with a 5 V DC supply. Confirm compatibility with your I/O base and existing network infrastructure.
