Schneider 172PNN21022C Modbus Communication Adaptor for Modicon Momentum

Technical Specifications Breakdown

Key parameters for the 172PNN21022C are listed below for quick reference:

Industry Applications

For example, in a packaging line where multiple Modicon Momentum I/O bases need synchronized data exchange, the 172PNN21022C ensures consistent data flow with its 5 V DC supply and 700 mA current capacity. Its compact Lexan housing and D-shell 9-pin connector simplify integration into existing cabinets.

Installation & Setup Guidance

Mount the adaptor on the I/O base as specified by the manufacturer. Connect the D-shell 9-pin connector to the Modbus network cable. Ensure the supply voltage is exactly 5 V DC from the I/O base to avoid damage. The LED provides local status indication for quick verification of power and communication activity.

Maintenance & Reliability

The lithium 2/3 AA battery supports clock drift of plus/minus 13 seconds per day, reducing the need for frequent adjustments. Inspect the D-shell connector periodically for corrosion or loose pins. The Lexan material offers good impact resistance, but avoid exposure to excessive moisture or chemicals.

Enhancing Modbus Communication in Modicon Momentum Systems

Industrial networks often face reliability challenges when integrating communication adaptors into existing control architectures. The Schneider Electric 172PNN21022C addresses this by providing a dedicated Modbus protocol adaptor for the Modicon Momentum series, ensuring stable data transfer in demanding automation environments.

Compatibility & Integration

This adaptor is designed for the Modicon Momentum series and uses the Modbus protocol. It receives power via the I/O base, simplifying cabling. The dielectric strength of 500 V DC ensures electrical isolation for safe integration with other system components.

Selection Guide & Purchasing Advice

When selecting a communication adaptor for your Modicon Momentum system, verify that the 172PNN21022C matches your network requirements. AutoDCSTech stocks this Schneider part for immediate shipment. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
