BMXCPS4002S | Schneider Electric Modicon X80 Redundant Power Supply Module

What Happens When Your PLC Power Supply Fails Mid-Production?

A power supply failure in a Modicon X80 rack can halt an entire production line in seconds. The Schneider Electric BMXCPS4002S redundant power supply module exists to prevent exactly that scenario. It is a safety-oriented power supply module engineered for Modicon X80 backplanes, delivering reliable, redundant power to I/O modules and processors.

This genuine Schneider Electric module accepts 100...240 V AC primary voltage and provides two independent secondary outputs: 15 W at 3.3 V DC for I/O module logic, and 40 W at 24 V DC for I/O modules and processor when 3.3 V is not loaded. With built-in redundancy and advanced diagnostics, it keeps your control system running even when one supply path falters.

Advanced Diagnostics and Redundancy

The BMXCPS4002S goes beyond basic power delivery. It offers redundancy testing, temperature sensing, remaining lifetime monitoring, and uptime duration tracking — all accessible via network. Three green status LEDs indicate voltage presence (OK), redundancy status, and power supply status. A RESET push-button enables cold restart when needed.

This diagnostic capability means maintenance teams can plan interventions before failures occur, reducing unplanned downtime and extending system service life.

Built for Demanding Environments

The module carries an impressive environmental and certification profile. It is certified for ATEX zone 2/22 and IECEx zone 2/22 hazardous locations, with Class I Division 2 compliance. Additional certifications include CE, UL, CSA, RCM, EAC, TÜV, and Merchant Navy.

The BMXCPS4002S resists vibration at 3 gn and shock at 15 gn. Its conformal coating protects against gas (class Gx ISA S71.04, class 3C4 IEC 60721-3-3), dust (3S4), sand (3S4), salt (level 2), mold growth (3B2), and fungal spores (3B2). It operates at altitudes up to 6561.68 ft (2000 m), with derating above that.

Where the BMXCPS4002S Delivers Value

This module suits process control, manufacturing automation, and safety-critical infrastructure where power interruptions are unacceptable. The redundancy feature makes it ideal for continuous-process industries — oil and gas, water treatment, and power generation — where an unexpected shutdown carries heavy costs.

Its ATEX and IECEx certifications open doors to hazardous-area installations, while the wide operating temperature range supports deployment in challenging climates.

Integration and Compatibility

The BMXCPS4002S works with all Modicon X80 backplanes, ensuring straightforward integration into existing Schneider Electric control architectures. Electrical connections include a 2-pin alarm relay connector and a 5-pin line supply connector with protective earth.

When integrating into networked control systems, note that advanced diagnostics are available via network. Depending on your architecture, this may require appropriate communication modules or gateways. Confirm cable and gateway requirements with your supplier before commissioning.
