Schneider 170PNT16020 Modbus Plus Adapter

Product Introduction

The Schneider Electric 170PNT16020 is a high-performance communication adaptor for the Modicon Momentum series. This module delivers reliable Modbus Plus network connectivity at a 1 Mbit/s transmission rate. It supports both token bus and peer-to-peer access methods, which makes it a flexible solution for distributed I/O systems. Its compact, industrial-grade construction ensures stable operation in clean automation environments. System integrators and maintenance engineers will find this component essential for robust industrial communication.

Technical Specifications

The 170PNT16020 communication adaptor offers efficient and dependable performance. It transmits data at 1 Mbit/s over standard twisted-pair cabling. This module supports two access methods simultaneously: token bus and peer-to-peer. These capabilities allow flexible network topologies and direct controller-to-controller data exchange. Dual SUB-D 9 connectors provide primary and backup network connections, which improves system redundancy and uptime. The adaptor draws its operating power directly from the I/O base, which simplifies the overall wiring design.

Mechanical & Environmental Parameters

The 170PNT16020 features a rugged design that suits demanding industrial settings. It operates reliably across a temperature range of 0 to 60 °C. The module also tolerates a maximum relative humidity of 95% without condensation, ensuring stable performance in varying indoor conditions. Additionally, this unit carries UL, CSA, and FM Class 1 Division 2 certifications, which confirm its compliance with strict safety and performance standards. The device functions properly at altitudes up to 5,000 meters above sea level.

Installation and Setup Guide

Installing the 170PNT16020 communication adaptor requires minimal effort. You simply plug the module directly into a Modicon Momentum I/O base, and it draws power from that base automatically. Its compact footprint of 18 x 26 x 5.5 cm allows efficient use of your panel space.

Three diagnostic LEDs on the front panel provide clear status feedback. A green MB + ACT LED indicates power and communication activity, while two red ERR A and ERR B LEDs signal cable errors on each network line. For network connections, the adaptor includes two 9-pin SUB-D connectors. You connect the primary Modbus Plus network to one port and may attach a redundant backup cable to the second for enhanced reliability. Remember to configure your network topology correctly and keep the device count per segment at or below 31 for optimal performance.
