140NOC78100C Schneider Quantum Control Network Module

Product Overview

The Schneider Electric 140NOC78100C is a high-performance Ethernet network module specifically engineered for the Modicon Quantum automation platform. This module serves as a versatile communication bridge, supporting both EtherNet/IP and Modbus TCP protocols. With a specialized protective coating for harsh environments and a lightweight design of 0.345 kg, it ensures reliable data exchange and network flexibility for complex industrial architectures.

Advanced Networking & Redundancy

Dual-Protocol & High-Speed Exchange

The 140NOC78100C operates in full duplex mode, facilitating simultaneous two-way data transmission at rates of 10 or 100 Mbit/s. It supports up to 64 concurrent connections, making it ideal for high-density I/O communication. Despite its compact 0.345 kg form factor, the module features an embedded 4-port switch and supports Rapid Spanning Tree Protocol (RSTP) for optimized network traffic management.

Hot Standby & Topology Flexibility

For mission-critical reliability, this module supports Hot Standby redundant architecture, ensuring seamless failover in the event of a network disruption. It is compatible with multiple network layouts, including Redundant Ring and Daisy Chain Loop topologies. The module's 0.345 kg rack-mountable design integrates easily into existing Modicon Quantum systems, drawing power directly from the backplane for simplified installation.

Technical Specifications

Embedded Services & Diagnostics

The 140NOC78100C is equipped with an embedded web server for remote monitoring and configuration. Key services include DHCP/BootP server functionality, SMTP e-mail notifications, and NTP time synchronization. The module provides clear local signaling via six front-facing LEDs, allowing maintenance teams to verify module status, network health, and communication activity at a glance. Its 0.345 kg build is IP20 rated and operates efficiently within a temperature range of 0°C to 60°C.

Industrial Reliability (Coated Version)

As a "C" suffix model, this module is conformal coated, providing superior resistance to humidity, dust, and chemical contaminants. This makes the 140NOC78100C the preferred choice for wastewater treatment, oil and gas, and heavy manufacturing sectors. The robust 0.345 kg module utilizes RJ45 10BASE-T/100BASE-TX ports and follows the standard Modicon Quantum format for guaranteed product compatibility with 140CPU6xxxx processors.

Technical FAQs

Q1: What is the benefit of the Coated (C) version?
A1: The conformal coating protects the internal circuitry from corrosion and environmental pollutants, extending the lifespan of the module in harsh industrial settings.

Q2: Can this module be used in a Hot Standby system?
A2: Yes, it is fully compatible with Schneider's Hot Standby redundant architecture, providing high availability for critical control applications.

Q3: Does the 0.345 kg weight include the rack mounting hardware?
A3: The 0.345 kg refers to the weight of the module itself. It is designed to slide into a standard Modicon Quantum rack, which handles the structural support.
