Product Overview

The GE IC695PSD040 is a high-performance, 40-watt DC power supply designed specifically for the PACSystems RX3i Universal Backplane. This module provides the primary regulated power required for the CPU, specialized modules, and standard I/O within a single rack. Engineered for simplicity and reliability, the IC695PSD040 converts a 24VDC input into the multiple voltage rails needed for backplane logic and internal circuitry.

As a non-redundant power solution, this module is intended for single-unit installation. It occupies one slot on the universal backplane and serves as a cost-effective energy source for small to medium-scale automation configurations. The unit features advanced internal diagnostics that integrate with the RX3i CPU to provide real-time status updates and fault reporting, ensuring that power-related events are captured within the system’s diagnostic logic.

Installation and System Safety

The IC695PSD040 is optimized for standard industrial environments where a stable 24VDC source is available. To maintain system integrity, it is vital to adhere to the single-supply installation rule. This module cannot be wired in parallel with other power supplies on the same backplane; doing so may result in equipment damage or unpredictable system resets. If the power budget of a single rack exceeds 40W, users should utilize expansion bases or remote I/O drops to distribute the load.

Furthermore, the module includes a specialized ground connection to ensure high noise immunity against electromagnetic interference (EMI). Its rugged design and lack of internal fans make it highly durable in dusty or high-vibration industrial settings. By strictly following the installation guidelines regarding version compatibility—particularly ensuring this 40W unit is not mixed with redundancy-capable modules—operators can guarantee a long service life and stable control system performance.
