FAQ

Q: Can this module operate with both AC and DC inputs?
A: Yes, the 1MRK002266-AAr00 supports a wide range of AC and DC station power sources.

Q: How does the internal fail contact function?
A: It signals SCADA or relay systems if output voltage drops below operational thresholds or the module experiences a fault.

Q: Is this compatible with half-size and full-size Relion 670 racks?
A: Yes, it fits both standard modular relay rack sizes without modifications.

Q: How does this PSM compare with similar ABB modules?
A: This module offers extended input voltage range, integrated fail signaling, and superior surge immunity compared to earlier PSM versions in the Relion 670 series.
