Product Overview
When network bottlenecks stall production, the 140NOC78000C from Schneider Electric delivers the throughput and reliability your control system demands. As an Ethernet digital input/output network module in the Modicon Quantum series, it handles full duplex communication across up to 128 simultaneous connections. That means two-way data transfers without delays—critical for real-time automation tasks.
This module operates at 10/100 Mbit/s transmission rates, so it keeps pace with modern industrial networks. Built-in redundancy adds a layer of operational stability, while the embedded web server simplifies remote configuration and monitoring. For oil, gas, and industrial automation applications, this is a practical, ready-to-ship solution.

What These Specs Mean in Practice
The 128-connection capacity lets you scale without swapping hardware. Full duplex means data flows both ways at once—no waiting for one transmission to finish before the next begins. RSTP support optimizes network performance and reduces transmission delays. The RJ-45 interface with twisted pair cabling keeps wiring straightforward and cost-effective.
Industry Applications
In oil and gas operations, this module connects remote I/O racks to the main control network, supporting real-time monitoring of pumps, valves, and safety systems. The redundancy feature helps maintain uptime when network paths fail—a direct ROI benefit for continuous processes.
Manufacturing plants use the 140NOC78000C to integrate Modicon Quantum PLCs with supervisory systems. The embedded web server allows technicians to check diagnostics from a browser, reducing troubleshooting time.
Water treatment facilities rely on its 10/100 Mbit/s throughput for data acquisition from distributed sensors. The IP20 rating suits control cabinets in clean, temperature-controlled environments.
Installation and Setup
Mount the module in a standard Modicon Quantum rack following the manufacturer’s guidelines. Use twisted pair cabling with RJ-45 connectors for network links. Verify ambient temperature stays between 0 °C and 60 °C. For RSTP configuration, consult your network administrator to enable rapid spanning tree where needed. Always follow local electrical codes and the official installation manual.
Compatibility and Integration
The 140NOC78000C integrates with Modicon Quantum PLC systems and supports Ethernet-based protocols through its RJ-45 interface. It works with standard twisted pair cabling. When wiring into existing networks, confirm gateway or connection module requirements with your supplier.
