Schneider 140CFJ00400 Modicon Quantum Fiber Optic RIO Interface

Product Description

The Schneider Electric 140CFJ00400 is a specialized fiber optic communication accessory for the Modicon Quantum PLC family. This module functions as a remote I/O head interface, enabling long-distance, noise-resistant communication between Quantum controllers and distributed I/O racks.

Engineered for demanding industrial environments, 140CFJ00400 delivers reliable data transfer over fiber optic links, eliminating EMI/RFI interference typical in process automation and utility applications. The module supports both field and loop power configurations, providing connections for plus, minus, shield, and power supply lines, along with 0.063 A fused points for analog input modules.

This terminal block accessory is compatible with Quantum I/O modules, including 140ACO02000, and is configurable via Schneider’s Concept, ProWORX, or Unity Pro software. Its design includes six terminals per point, captive screw connections, and DIN rail mounting for secure installation.

Functional Overview and Applications

140CFJ00400 enables robust remote I/O communication in large-scale automation projects, particularly in oil & gas, chemical processing, power generation, and water treatment facilities. It facilitates distributed I/O deployment while maintaining signal integrity and reliability across extended fiber optic networks.

This module is ideal for systems requiring noise-immune, deterministic communication over long distances, offering built-in diagnostics via LED indicators for quick verification of operational status and fault detection.
