Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140CPS12420 is a Schneider Modicon Quantum power supply module, order code 140-CPS-124-20, delivering 11 A at 5.1 V DC from a 115 V AC input in a redundant topology. It is chassis-mounted and carries CE marking, UL 508 and CSA C22.2 No 142 certifications, with an internal output overload protection and a 2 A slow-blow associated fuse. This module supplies logic power to the Quantum backplane and I/O racks. The redundant topology means two units can be paralleled for fault-tolerant operation — if one drops, the other holds the 5.1 V DC rail without a glitch. The 11 A output current supports a fully loaded Quantum rack with multiple I/O modules; the 1.1 A input draw at 115 V AC gives a rough efficiency check for panel heat budgeting. An internal overload protection prevents sustained overcurrent damage, backed by the 2 A slow-blow fuse on the AC line. A green LED (PWR OK) provides local status, and a normally-closed alarm output rated 6 A at 220 V signals a power supply fault to the PLC or annunciator. ## Applications The 140CPS12420 is used in Modicon Quantum automation platforms for continuous process control, water treatment, material handling, and manufacturing lines where redundant power is specified to avoid a single-point failure bringing down the controller. ## Compliance & certifications The module carries CE marking, UL 508, CSA C22.2 No 142, and cUL product certifications. It also notes California Proposition 65 compliance. No RoHS or REACH declarations are listed in the available evidence. Within the Modicon Quantum range, the 140CPS12420 is the redundant 11 A power supply option, specified when the application demands fault-tolerant backplane power. It sits alongside standard (non-redundant) Quantum supplies and is a direct fit in the same chassis slot.","metaTitle":"Schneider 140CPS12420 Modicon Quantum Power Supply, 11 A, 5.1 V DC","metaDescription":"Schneider Modicon Quantum 140CPS12420 redundant power supply module: 115 V AC input, 11 A output at 5.1 V DC, CE, UL 508, CSA.
