Product Overview

The 140CPU67160 (Model: 140CPU67160) represents the pinnacle of reliability for the Schneider Electric Modicon Quantum platform. This high-availability Unity processor is specifically engineered for mission-critical automation environments where downtime is not an option. Operating at a high-speed 266 MHz clock frequency, it provides the deterministic logic execution and computational bandwidth required for large-scale distributed architectures and complex floating-point process control.

The standout feature of the 140CPU67160 (Part Number: 140CPU67160) is its integrated Hot Standby (HSBY) capability. Unlike standard processors that require separate sync modules, this unit features a built-in MT-RJ multimode fiber optic interface for high-speed synchronization between primary and standby controllers. This ensures a "bumpless" transfer of control and state data in the event of a system fault, maintaining process continuity in oil and gas refineries, power plants, and large-scale water treatment facilities.
