Schneider 140CPU67260 Unity Hot Standby Processor for Modicon Quantum

Product Introduction

When high-availability control is non-negotiable, the Schneider 140CPU67260 delivers robust Hot Standby redundancy for critical processes. Part of the Modicon Quantum automation platform, this Unity processor integrates multimode Ethernet connectivity with 3072 kB of internal RAM and a 266 MHz clock frequency. It supports up to 2 local racks and extensive remote I/O configurations, making it a reliable choice for demanding industrial environments.

Technical Specifications Breakdown

The 140CPU67260 offers a clock frequency of 266 MHz, ensuring fast execution of control logic. Its internal RAM of 3072 kB includes 1536 kB dedicated to data, with expandable program memory up to 7168 kB via a PCMCIA card and file storage up to 8 MB. The processor supports multimode transmission over fiber optic links up to 4 km for Hot Standby synchronization. It provides 10.28 Kinst/ms for 100% Boolean operations and 10.07 Kinst/ms for mixed Boolean and numerical tasks. The bus current requirement is 2760 mA.

Industry Applications

This processor excels in applications requiring uninterrupted operation, such as oil and gas pipelines, power generation, and water treatment plants. In a Hot Standby configuration, the 140CPU67260 ensures seamless failover, minimizing downtime. Its support for up to 63 distributed I/O stations and 31 remote I/O stations makes it suitable for large-scale distributed control systems. The multimode fiber optic link enables reliable synchronization between primary and secondary PLCs over distances up to 4 km.

Installation & Setup Guidance

When installing the 140CPU67260, ensure proper mounting in the Modicon Quantum rack. Connect the multimode fiber optic cable using the MT-RJ connector for Hot Standby communication. Use the RJ45 connector for Modbus bus and the SUB-D 9 connector for Modbus Plus network. Verify that the bus current requirement of 2760 mA is within the power supply capacity. Configure the key switch for memory port on/off control as needed.
