FAQ

Q: Can the 140CPS12400 operate without redundancy? A: Yes, it can function as a standalone power supply, but redundancy requires pairing with a second identical module.

Q: Is this module compatible with Modicon M340 or X80 systems? A: No, it is designed specifically for the Modicon Quantum platform. For X80 systems, BMXCPS4002 is the recommended alternative.

Q: What happens in case of power supply failure? A: In a redundant configuration, the secondary module automatically maintains system operation without interruption.
