Product Description

Description

The Schneider Electric Modicon Quantum 140CPS11420 is a summable or standalone AC power supply module designed to deliver regulated power to backplane components within the Modicon Quantum automation platform. Operating on nominal input voltages of 115 VAC or 230 VAC, the unit converts main power sources into a stable 5.1 VDC output, delivering up to 11 A in standalone mode or up to 20 A when used in a summable configuration at 60 degC.

Engineered to support system reliability, the 140CPS11420 integrates internal overvoltage and overload protection mechanisms alongside a dedicated power-loss alarm relay output (1 NC contact rated for 220 VAC at 6 A / 30 VDC at 5 A). Front-panel diagnostic reporting is provided via a green PWR OK LED. Grounded within standard Quantum backplane racks, the module provides stable internal current distribution for installed CPUs, communication modules, and I/O slices.

Features

Flexible operational modes allowing standalone (11 A) or summable (up to 20 A) power expansion.
Dual AC input voltage support for 115 VAC (93...132 VAC) and 230 VAC (170...276 VAC) lines.
Integrated internal overvoltage and overload protective circuitry to protect internal system components.
Hardwired power-loss alarm output featuring a normally closed (NC) dry relay contact set.
Clear local diagnostic feedback via a dedicated green PWR OK panel LED indicator.
Standard Modicon Quantum backplane form factor for standard rack installation.

Applications

Primary backplane power distribution for Modicon Quantum PLC rack configurations.
Summable power architecture in high-density, multi-module I/O racks requiring current beyond 11 A.
System monitoring interfaces utilizing the fault relay output for external mains loss reporting.

Installation Guidelines

Verify that the system main power is disconnected prior to inserting or removing the power supply from the Quantum backplane.
Confirm input line voltage settings; ensure terminal pins 3 and 4 have a jumper installed for 115 VAC operation, or leave open for 230 VAC operation.
Align the module with the dedicated slot in the Quantum rack and seat it firmly into the backplane connector.
Wire the AC mains supply to terminal 5 (AC L) and terminal 6 (AC N), and attach the protective grounding line to terminal 7.
If auxiliary monitoring is required, wire external alarm loops through the NC dry relay contacts on terminals 1 and 2.
Verify that an external 2.0 A slow-blow fuse is installed in the line circuit prior to energizing the module.

Configuration / Commissioning / Replacement Recommendations

Summable Operation Compatibility: Combine only approved AC summable power supply models (such as 140CPS11420 or 140CPS11410) within the same backplane rack. Do not mix AC power supplies with DC models (e.g., 214 00 or 414 00) in summable configurations.
Software Power Calculations: Note that legacy programming software (such as ProWORX NxT versions prior to v2.2 SR8) may calculate power consumption incorrectly for 11 A modules. Calculate backplane power totals manually when configuring racks in legacy software environments.
Replacement Procedure: When replacing a failed module, power down the rack feed, disconnect the 7-point terminal connector, release the top/bottom rack seating levers, replace the hardware, and reconnect the terminal block without altering cabinet field wiring.

FAQ

What is the primary function of the Schneider Electric Modicon Quantum 140CPS11420?

The Schneider Electric Modicon Quantum 140CPS11420 is an AC power supply module that converts incoming 115 VAC or 230 VAC supply power to 5.1 VDC to provide internal operating power to modules residing on a Modicon Quantum PLC backplane rack.

What output current can the 140CPS11420 module supply?

The module provides up to 11 A at 5.1 VDC when used in standalone mode at 60 degC. When configured with another compatible summable power module in the same rack, total available backplane output current increases to 20 A.

How do you select between 115 VAC and 230 VAC input operation on the 140CPS11420?

Voltage selection is set at the 7-point front terminal connector. A jumper wire must be installed between terminal pins 3 and 4 for 115 VAC input operation, whereas these pins are left unconnected for 230 VAC operation.

Can the 140CPS11420 AC power supply be paralleled with DC power supply modules?

No, according to Schneider Electric compatibility matrices, AC power supply modules like the 140CPS11420 can only be paired with compatible AC summable models (such as the 140CPS11410). Combining AC and DC power modules in a summable configuration is prohibited.
