Description

Brief Product Description

The General Electric IC693PSA040 is a 40-watt high-performance power supply designed for the PACSystems RX3i universal backplane. It supports a broad range of AC and DC input voltages to provide stabilized power for CPUs, logic modules, and field circuitry.²

Product Description

Versatile Power Regulation and Distribution

The GE IC695PSA040 serves as a primary power source for the PACSystems RX3i controller platform. This module converts a wide range of incoming energy—specifically 85–264V AC or 100–300V DC—into three regulated output rails.³ It provides +3.3V DC for internal backplane logic, +5.1V DC for module power, and a +24V DC relay output for external field devices.⁴ By integrating these three rails into a single 40-watt module, the unit ensures that every component in a standard RX3i chassis receives clean, noise-filtered electricity.

Operational Safety and Diagnostics

Advanced monitoring capabilities define the IC695PSA040 architecture. The front panel features four dedicated LED indicators that provide real-time status updates for Power, P/S Fault, Over Temperature, and Overload conditions. These diagnostics allow maintenance teams to identify thermal or electrical issues before they result in system downtime.⁵ Additionally, a recessed ON/OFF switch is located behind a protective hinged door. This switch includes a mechanical tab to prevent accidental actuation, though it is important to remember that it toggles output power without isolating the high-voltage input terminals.

Chassis Integration and Requirements

Engineers designed the GE Fanuc IC695PSA040 specifically for the RX3i Universal Backplane. While it offers robust performance for compact systems, it does not support parallel redundancy or capacity expansion.⁶ Therefore, this module must be the sole power supply within its backplane segment. If a system’s power requirements exceed the 40-watt threshold, technicians must distribute the load across expansion bases. This focused design makes the module an efficient and cost-effective choice for standalone automation racks and dedicated machine control setups.
