Schneider 140NOC78100C Ethernet Module

The 140NOC78100C provides Ethernet communication for Quantum PLC systems. This module connects control networks to field devices and supervisory systems. Its rectangular frame measures 166 millimeters in width. The module height reaches 140 millimeters exactly. Depth stays at 115 millimeters. You will find this unit weighs approximately 0.65 kilograms. Therefore, installation requires sliding the unit into a standard Quantum rack slot. One front-panel RJ45 port serves as the primary Ethernet connection.

Physical Layout and Connectors

The front panel features a single shielded RJ45 Ethernet port. A second RJ45 port provides daisy-chain connectivity for additional modules. Three status LEDs indicate link activity, speed, and collision status. Two rotary switches allow manual IP address segment selection. Four mounting screws secure the module firmly in the rack.

Internal Design and Energy Storage

The 140NOC78100C contains exactly 286 discrete components onboard. A 560 microfarad capacitor bank filters noise from the internal power supply. Dual network controllers handle Ethernet traffic on each port independently. The module includes galvanic isolation for all network interfaces. A dedicated 32-bit processor manages protocol stacks efficiently. Flash memory stores firmware and configuration data persistently.

Operational Performance

This Ethernet module supports Modbus TCP communication with up to 32 devices. It allows web-based configuration through any standard browser. Moreover, the unit provides SNMP for network management systems. You can daisy-chain multiple modules using the second Ethernet port. The module auto-negotiates speed and duplex settings automatically. Three LEDs show real-time network status for troubleshooting. Consequently, you achieve reliable network connectivity for Quantum systems. Schneider designed this module for industrial control networks. Its metal housing provides excellent electromagnetic shielding.

In summary, the 140NOC78100C delivers robust Ethernet communication capability. Use this module for remote I/O or SCADA integration. It simplifies network connectivity with dual-port daisy chaining. Order this Ethernet module for your Schneider Quantum system.
