Schneider 172JNN21032C Serial Link Option Adaptor for Modicon Momentum

Product Overview

When integrating serial communication into a Modicon Momentum automation platform, the Schneider Electric 172JNN21032C serial link option adaptor provides a reliable and flexible solution. This unit supports selectable RS232 or RS485 serial links, making it suitable for diverse industrial networking needs. Its compact design and robust certifications ensure dependable performance in demanding environments.

Technical Specifications Breakdown

The 172JNN21032C operates with a rated supply voltage of 5 V DC and draws 700 mA at 12 V DC. It features a lithium 2/3 AA battery with a 5-year life, providing backup for critical settings. After a low battery indication at 40°C, battery autonomy remains under 30 days. The adaptor offers a dielectric strength of 500 V DC and includes one LED for communication status. It measures 0.98 inches (25 mm) in height, 5.6 inches (143.1 mm) in width, and 2.36 inches (60.06 mm) in depth, with a net weight of 3.00 oz (85.05 g).

Industry Applications

This serial link option adaptor is ideal for applications requiring reliable point-to-point or multi-drop serial communication. In manufacturing plants, it connects programmable logic controllers to remote I/O devices or operator interfaces. Its RS485 capability supports longer cable runs and multiple devices, reducing wiring complexity. The 172JNN21032C also suits building automation systems where legacy serial devices need integration into modern control networks.

Installation & Setup Guidance

Mount the adaptor securely on a DIN rail or panel using the standard Modicon Momentum form factor. Connect the communication port via the 1 connector D-shell 9 pins for Modbus Plus connection. Ensure the supply voltage is within 5 V DC ±5% and provided through the I/O base. Select RS232 or RS485 mode as required by your network topology. Verify the LED indicates proper communication status after power-up.

Maintenance & Reliability

The 172JNN21032C includes a lithium battery with a 5-year life, reducing the need for frequent replacements. Monitor the LED for communication status; a low battery warning at 40°C signals that backup power will last less than 30 days. The conformal coating (Humiseal 1A33) protects against moisture and contaminants, enhancing reliability in harsh industrial environments. Periodic inspection of connections and environmental conditions ensures long service life.

Compatibility & Integration

This adaptor integrates seamlessly with the Modicon Momentum automation platform. It supports RS232 or RS485 serial links, selectable per application requirements. The device is compatible with Modbus Plus networks via the D-shell 9-pin connector. Certifications include UL, CUL, CE, FM, CSA, and NEMA 250 Type 1, ensuring broad acceptance in global installations.

Selection Guide & Purchasing Advice

Before purchasing, verify that your system requires a serial link option adaptor for Modicon Momentum. Confirm the communication protocol (RS232 or RS485) and ensure the I/O base provides 5 V DC supply.
