140CPS11100 Schneider Power Supply Module – Product Description

Brand ABB

Model 140CPS11100

The 140CPS11100 is a standalone AC power supply module from Schneider Electric’s Modicon Quantum automation platform, engineered to deliver regulated 5.1 VDC output at 3 A for Quantum PLC racks and associated I/O modules . As a standalone unit, the Schneider 140CPS11100 operates independently of the rack backplane power distribution, making it suitable for applications where a dedicated, isolated power source is required for the control system or where redundancy is mandated. The module accepts a wide input voltage range of 120 to 230 VAC (100 to 276 VAC operational), accommodating both North American and European industrial power standards without external transformers or reconfiguration .

Within the Modicon Quantum architecture, the 140CPS11100 occupies a standard module slot and provides the 5.1 VDC logic power required by the PLC’s processor and I/O modules through the backplane. Its standalone designation distinguishes it from rack-mounted redundant power supplies, offering a simpler, cost-effective solution for systems with moderate power requirements. The module’s internal overvoltage and overload protection circuits safeguard connected equipment against input transients and output faults, while a front-panel green LED (PWR OK) provides immediate visual confirmation of power status . The Schneider 140CPS11100 is certified to UL 508 and CSA C22.2 No. 142 standards, with cUL listing and FM Class 1 Division 2 approval for use in hazardous locations .

Despite its formal discontinuation by Schneider Electric in June 2024, the 140CPS11100 remains widely deployed across legacy Modicon Quantum installations in manufacturing, process control, and infrastructure applications . Its continued relevance stems from the extensive installed base of Quantum systems and the practical necessity of maintaining spare power supplies for critical control loops. The Schneider 140CPS11100 therefore represents both a proven power solution for existing Quantum deployments and a critical spare part for facilities committed to extending the service life of their automation assets.

Main Features and Advantages

Dual-Voltage Input Flexibility: The Schneider 140CPS11100 accepts both 115 VAC and 230 VAC input without requiring external jumpers, transformers, or manual reconfiguration. This dual-voltage capability simplifies inventory management and deployment across facilities with mixed power infrastructure, reducing the risk of misconfiguration during installation or replacement . The wide operational input range of 100 to 276 VAC provides additional tolerance for brownouts and voltage sags common in industrial environments.

Integrated Protection Circuitry: Internal overvoltage and overload protection circuits within the 140CPS11100 continuously monitor output conditions and automatically limit or shut down output in fault scenarios. Unlike designs that rely on external protection devices, this integrated approach reduces component count, simplifies wiring, and ensures that protection response times are matched to the power supply‘s internal characteristics . The associated 1.5 A slow-blow input fuse provides additional protection against input-side faults .

Straightforward Diagnostics and Monitoring: A single green LED on the 140CPS11100 front panel provides immediate, unambiguous confirmation that the module is powered and the internal bus voltage is within specification. While simple, this diagnostic capability is sufficient for most standalone applications, where the power supply’s role is binary: either it is functioning or it is not. The LED’s placement on the module faceplate ensures visibility during routine cabinet inspections without requiring access to the PLC programming software .

Proven Reliability in Demanding Environments: With an operating temperature range of 0 to 60 °C, 95% relative humidity tolerance, and FM Class 1 Division 2 certification, the Schneider 140CPS11100 is engineered for the environmental conditions typical of industrial control rooms, process cabinets, and hazardous-area installations . Its convection-cooled design eliminates moving parts and filter maintenance requirements, contributing to a long, low-maintenance service life.

Compact Standard-Format Footprint: The 140CPS11100 occupies a single standard slot in the Modicon Quantum rack, preserving valuable I/O capacity for application-specific modules. Its net weight of 0.65 kg and straightforward rack-mounting design facilitate rapid field replacement, minimizing mean time to repair in the event of power supply failure .
