Product Description

The BMXCPS3020 is an isolated DC power supply module for the Schneider Electric Modicon X80 platform. It provides regulated backplane power for PAC systems such as the Modicon M580 and Modicon M340.

Designed for 24–48 V DC input, the BMXCPS3020 features a fully isolated DC-to-DC architecture, preventing field-side noise or surges from affecting CPU and I/O modules. Its high efficiency, controlled inrush current, and diagnostic LED indication make it suitable for mission-critical industrial environments.

Frequently Asked Questions

Q1: What is the benefit of isolation?
Electrical isolation prevents ground loops and protects the controller from voltage spikes on the DC supply line.

Q2: Can it power field devices?
No. It supplies only the rack backplane. Field sensors and actuators require a separate external 24 V DC power supply.
