Schneider 172PNN21022C Modbus Adaptor

172PNN21022C Schneider Modicon Momentum Adapter

Product Introduction

The 172PNN21022C from Schneider Electric serves as a vital link for Modicon Momentum control systems. This adaptor enables seamless data exchange using the widely adopted Modbus protocol. Furthermore, it operates on a stable 5 V DC supply, which it receives directly through the I/O base. With a current consumption of 700 mA, this device handles demanding communication tasks effectively. Its compact dimensions and lightweight construction make it suitable for various industrial enclosures. Therefore, this adapter provides a dependable solution for modern automation networks.

Technical Specifications

This section details the core technical attributes of the Schneider Electric 172PNN21022C. The unit supports the Modbus communication type, ensuring compatibility with numerous PLCs and field devices. Its rated supply voltage is 5 V DC, and it powers up via the connected I/O base. The internal clock exhibits a drift of ±13 seconds per day, which is adequate for routine time-stamping functions. Moreover, it incorporates a lithium battery of size 2/3 AA, providing backup power for internal operations. The electrical connection is established through a single D-shell 9-pin connector, which simplifies cabling. Meanwhile, the local signalling is managed by a clear LED indicator, allowing for quick status checks. The device also guarantees a dielectric strength of 500 V DC, confirming its robust electrical isolation.

Mechanical and Environmental Features

The housing of the 172PNN21022C is constructed from Lexan, a material known for its high impact resistance and dimensional stability. Consequently, this adaptor withstands harsh industrial conditions without degrading. Its physical dimensions are minimal: a height of 1 inch, a width of 5.6 inches, and a depth of 2.3 inches. Additionally, the total weight is a mere 85.05 grams, which minimizes stress on mounting rails and backplanes. This lightweight design also facilitates easy handling during installation or maintenance procedures. Therefore, its mechanical properties contribute significantly to its overall reliability and longevity in the field.

Installation Guidelines

Installing the Schneider 172PNN21022C is a straightforward process. First, ensure the system power is completely disconnected to avoid any electrical hazards. Next, locate the dedicated communication slot on the Modicon Momentum I/O base. Then, carefully align the adaptor's D-shell connector with the corresponding port on the base. After that, secure the adaptor firmly in place by tightening the retaining screws. Finally, reconnect the system power and verify that the LED indicator illuminates correctly. For optimal performance, avoid placing this unit near high-voltage cables or heat sources. Remember to handle the internal lithium battery with care during any disassembly.
