Product Description
Overview
The Emerson KJ1501X1-BA1 (12P0550X022) is a dual-channel redundant power supply module designed for the DeltaV™ M-Series Distributed Control System (DCS). It provides regulated logic power to controllers, I/O modules, and workstation interfaces, ensuring continuous system operation in critical industrial environments.
This modular, rail-mounted power supply supports hot-swappable operation and parallel installation for redundancy. Its compact design simplifies integration while delivering reliable performance under varying electrical and environmental conditions.
Key Features
Dual-Channel Redundancy
Two independent channels allow parallel operation. If one channel fails, the second maintains full output without interruption, supporting zero-downtime control.
Hot-Swappable Design
Modules can be replaced or serviced while the system remains online, avoiding operational interruptions.
Wide Input Voltage Range
Accepts 85–264 VAC, accommodating global power standards.
High Efficiency
Optimized for low power loss and reduced heat generation, supporting efficient cabinet operation.

FAQ
Q: Can the KJ1501X1-BA1 be installed alongside another module for redundancy?
A: Yes, two modules can be operated in parallel for full redundancy and bumpless load transfer.
Q: Is this power supply suitable for field devices?
A: No, it is intended only for system logic power. Field devices require dedicated high-current power modules.
Q: What happens if the module fails while online?
A: The second redundant channel immediately assumes full load, maintaining uninterrupted system operation.
Q: Can this unit operate in harsh industrial environments?
A: Yes, it is rated for temperature extremes, humidity, vibration, and includes conformal coating and EMI/RFI protection.
