Reliable Communication for Industrial Automation
The Schneider Electric 170PNT16020 is a reliable and high-performance Modbus Plus communication adapter, explicitly designed for the Modicon Momentum automation platform. Also known by its model number 170-PNT-160-20, this industrial-grade accessory plays a critical role in enabling advanced network connectivity and communication between devices within automation systems. It provides a powerful link between I/O bases and Quantum PLCs, making it an essential component in complex Modbus Plus networks that demand reliability, speed, and redundancy.
This communication adapter features two SUB-D 9-pin connectors, one for standard Modbus Plus network communication and another for redundant networking. This dual-port design ensures continuous operation and increases system reliability in critical industrial environments. With support for redundant network topologies, the 170PNT16020 is capable of maintaining operations even in the event of a partial network failure, making it an ideal solution for industries requiring high availability and reduced downtime.
Operating on a token bus protocol, this adapter enables peer-to-peer communication and achieves a transmission rate of 1 Mbit/s over a twisted-pair cable. It supports multiple topologies, including multidrop configurations and device connection through extension or tap-off cables. Each segment of the network can include up to 31 devices, with a total of up to 63 devices supported across all segments when using repeaters. The maximum supported cable length is an impressive 5,000 meters (16,404.2 feet), allowing for expansive network layouts across extensive facilities.
The 170PNT16020 is designed to handle fault conditions gracefully, supporting fail states such as fallback to zero, forcing to zero state, full-scale value, or maintaining the last value. This capability ensures that even in adverse conditions, system behavior can be predicted and managed to avoid unsafe states or unnecessary shutdowns.
The device draws its power directly from the I/O base, making installation clean and streamlined with minimal additional wiring. Explicit local signaling is provided via integrated LEDs, including a green LED that indicates module power or activity and two red LEDs for communication errors on network A and network B. This built-in status indication enables quick diagnostics and system monitoring, allowing maintenance personnel to identify and resolve issues more efficiently.
Certified with CE marking and compliant with IEC 61131-2 standards, the 170PNT16020 meets the requirements of modern industrial automation environments. Available from MRO Electric and Supply, this communication adapter comes with a 2-year warranty and qualifies for free shipping, ensuring fast delivery and peace of mind. Whether you're upgrading an existing system or building a new automation architecture, this adapter delivers robust connectivity and dependable performance.
