The IC695PSD040M is a high-performance, 40-watt power supply designed for the PACSystems RX3i controller platform. This module is engineered to provide reliable DC power to the RX3i backplane, supporting the CPU and various I/O modules within the rack. As a “Universal” power supply, the Emerson IC695PSD040M features advanced diagnostic capabilities and is specifically designed to occupy a single slot, maximizing the available space for functional modules in the system.

Application Fields
The IC695PSD040M is a staple in industrial automation and process control environments, particularly in sectors such as water treatment, power generation, and manufacturing. It is ideal for systems where 24V DC is the primary control power source, such as in remote terminal units (RTUs) or localized control panels. Because it supports the RX3i’s hot-swap capability (when used in a universal backplane), it is frequently used in mission-critical applications where minimizing downtime during maintenance is essential.
Product Instructions
The power supply should be installed in the leftmost slot (Slot 0) of a PACSystems RX3i Universal Backplane, though it can be placed in other slots depending on the power requirements of the rack. Before mounting, ensure the input power is disconnected. The module is secured by tightening the top and bottom screws to ensure a solid ground connection to the backplane. The 24V DC input should be wired to the front terminal strip using appropriately gauged copper wire. Monitor the status LEDs: a solid “PWR” LED indicates the module is operating correctly. If the “FAULT” LED illuminates, check for an overload condition or a short circuit in the backplane.
Common Questions and Answers
Q: Can I use multiple IC695PSD040M modules in a single rack for redundancy? A: No, the RX3i system does not support load-sharing redundancy with this specific 40W DC model. If your application requires redundant power, you must use specialized redundant power supply modules (such as the IC695PSD140) and a redundancy-capable backplane.
Q: Does this power supply provide power to field devices? A: No. The IC695PSD040M is designed exclusively to provide internal power to the CPU and modules via the backplane. External field devices (like solenoids or sensors) must be powered by a separate external 24V DC power supply.
Q: What is the difference between the IC695PSD040 and the IC695PSD040M? A: The “M” suffix often denotes a version intended for specific regional markets or a specialized manufacturing revision that may include updated hardware components while maintaining full functional compatibility with the standard version.
