Schneider Electric 172JNN21032 Overview

The 172JNN21032 is a Serial Option Adapter that provides additional Modbus port functionality for use with the TSX Momentum PLC series. The adapter offers a user-selectable RS232/RS485 slave functionality through Modbus Port 2, which is a general-purpose asynchronous serial port. This port can be used for various purposes, such as connecting external devices, communicating with other systems, and more.
The adapter comes with a front panel that includes an LED indicator, a battery compartment door, and the Modbus Port 2 connector. The LED indicator is used to show activity on the RS232/RS485 serial port, and it may be on steadily or blinking. The battery compartment door houses two AAA alkaline batteries, which power the adapter's time-of-day clock. The adapter's TOD clock is accurate to +/-13 seconds per day and has a service life of fewer than 30 days from a battery-low indication received to actual battery failure. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry Adapters from other manufacturers such as Modicon and ABB.


The adapter can operate in a wide range of temperatures and humidity levels, making it suitable for various environments. It is also designed to meet CE mark requirements for open equipment and has agency approvals from UL, CSA, CUL, CE, and FM class 1, div2 (pending). Furthermore, it has been tested for vibration and shock according to IEC standards, ensuring its reliability.


One of the adapter's unique features is its auto-logout feature, which is activated when the RS232 port is chosen. This feature automatically logs out of the port if a programming panel is disconnected, preventing a lock-up situation that could prevent other host stations from logging in on other ports.

Overall, the 172JNN21032 Serial Option Adapter is a reliable and versatile option for adding a Modbus port to a TSX Momentum PLC system. Its user-selectable RS232/RS485 slave functionality, front panel with an LED indicator, and auto-logout feature make it a convenient and efficient addition to any system.
