Emerson DeltaV KJ1501X1-BA2 System Power Supply – M-Series AC/DC | In Stock & Request a Quote

Introduction

The Emerson DeltaV KJ1501X1-BA2 System Power Supply is a vital component of the DeltaV M-series Traditional I/O subsystem, providing reliable AC-to-DC power conversion for field devices and I/O interfaces. As part of Emerson's field-proven DeltaV architecture, this power supply ensures stable, uninterrupted power distribution across your process control infrastructure.
Traditional I/O is a modular subsystem that offers flexibility during installation. It is designed to be installed in the field, near your devices. Traditional I/O is equipped with function and field wiring protection keys to ensure that the correct I/O card is always plugged into the corresponding terminal block. Modularity, protection keys, and plug-and-play capabilities make DeltaV Traditional I/O a smart choice for your process control system.
Whether you are maintaining an existing DeltaV installation, expanding your M-series I/O footprint, or sourcing hard-to-find spares, the KJ1501X1-BA2 remains a trusted choice for engineers and procurement teams worldwide.

Key Benefits

Decreases Capital Equipment Costs

Full System Modularity: The Traditional I/O subsystem was designed with your investment in mind. All components are fully modular and may be installable under power. You add I/O interface carriers and I/O interfaces in groups of 4, 8, 16, or 32 channels as you need them. The modular design enables you to purchase the exact amount of I/O cards, 8-wide or 4-wide carriers, power/controllers, and 2-wide carriers you need — and add more DeltaV I/O as your system grows.
Reduced System Footprint: The DeltaV system's state-of-the-art form factor design of the I/O components enables you to mount the I/O interface carrier in a junction box in the field, significantly reducing the footprint of your equipment and increasing valuable control room space for other uses.
Installation Savings: Save on wiring expenses by installing Classic Instrumentation in the field, near the actual field devices. Mounting the controller with the I/O further reduces your wiring expenditures by eliminating the need for long runs of multi-cores. The integrated design of the Traditional I/O subsystem can eliminate the need for marshalling panels — saving you even more in total capital costs. The provision of in-line fuses and bussed power saves on installation costs compared with external fuses and power distribution.

Decreases Installation Time and Expense

Plug-and-Play Installation Saves Money: All Traditional I/O components plug into the I/O interface carrier. You can install the I/O interface carriers to manage anticipated growth and postpone the I/O interfaces until you are ready to install your additional field devices.
Phased Installation Saves Time: As soon as you mount the I/O interface carrier, you are ready to begin installing the field devices. I/O terminal blocks plug directly onto the I/O interface carrier. There is no need to have the I/O cards installed.
Keys: Traditional I/O interfaces and terminal blocks have I/O function keys. These keys ensure that the correct I/O card is always plugged into the corresponding terminal block. It is incredibly easy to use and gives you time to do more. This design enables you to initially install Traditional I/O quickly and efficiently. When you need to replace an I/O card, the function key design ensures that you will always install it correctly. This keying system provides a safety measure by preventing the wrong I/O interface from being installed.

Increases Productivity

Real-Time, Online Equipment Additions: Online addition of new I/O interfaces means your process does not get interrupted. As new equipment is added, the DeltaV Explorer acknowledges it and assigns it basic configuration.

Increases Process Availability

1:1 Redundancy for Traditional and HART I/O Cards: DeltaV redundant I/O uses the same Series 2 I/O cards as non-redundant I/O. This allows you to leverage your investment in installed I/O and in I/O spares. No additional configuration is needed when using a redundant channel. The redundant terminal blocks provide the same field wiring connections as simplex blocks, so there is no extra wiring needed.
Autosense of Redundancy: DeltaV autosenses redundant I/O, which greatly simplifies the task of adding redundancy to the system. The redundant pair of cards is treated as one card in the system tools.
