Schneider Electric 140NOC78100C Modicon Quantum Network Module

The 140NOC78100C is a high-performance Ethernet communication module designed by Schneider Electric for the Modicon Quantum automation platform. Featuring conformal coating for harsh environment protection, this module manages simultaneous EtherNet/IP and Modbus TCP protocol traffic over twisted-pair copper media. It offloads network management tasks from the local rack controller while facilitating high-speed data exchange across industrial networks.

Multi-Protocol Communication and Topology Flexibility

Equipped with dual protocol support, the module functions in full-duplex mode to deliver simultaneous two-way transmission at 10 or 100 Mbit/s. It supports up to 64 concurrent connections, making it suitable for distributed I/O integration, peer-to-peer controller messaging, and supervisory system interfacing.

For versatile field wiring, the hardware supports both Daisy Chain Loop and Redundant Ring topologies. These configurations permit resilient cabling layouts directly between rack locations, minimizing external switch infrastructure while maintaining ring recovery mechanisms.

High Availability and Conformal Coating Protection

Designed for mission-critical installations, the 140NOC78100C integrates into Hot Standby redundant controller architectures to ensure uninterrupted network access during CPU failover events. An embedded web server provides real-time system monitoring and diagnostic access directly through a standard web browser.

The "C" suffix designates a factory-applied conformal coating on the internal circuit assemblies, protecting electronic components from airborne moisture and industrial chemical contaminants. The IP20 module mounts directly into standard Modicon Quantum rack backplanes and operates in ambient temperatures from 0 to 60 deg C.
