Schneider 170NEF11021 Modbus Interface for Momentum PLCs

Description

The Schneider Electric170NEF11021 Modbus Plus communication adaptoris designed toconnect Modicon Momentum I/O bases to Modbus Plus networks. Operating at1 Mbit/s, it supportspeer-to-peer token bus communication, allowing fast and deterministic data exchange between PLCs and field devices. This module is ideal forindustrial environments requiring robust and scalable networking. The adaptor supportsmultidrop topologyand can connectup to 31 devices per segment, or63 across all segments using repeaters. It featuresLED indicators for power, activity, and communication errors, simplifying diagnostics and maintenance. The 170NEF11021 is compatible withCompact 984 and Quantum PLCs, making it a flexible solution forlegacy and hybrid systems. It drawspower directly from the I/O base, reducing wiring complexity and installation time.
