Description

Brief Product Description

The GE Fanuc IC695PSA140 is a high-reliability 40-watt power supply designed for the PACSystems RX3i platform, supporting both AC and DC input ranges.³ This multipurpose module enables load-sharing and redundancy configurations to ensure continuous operation for mission-critical industrial automation tasks.⁴

Advanced Load-Sharing and Redundancy

The GE Fanuc IC697CMM741 operates as a high-capacity energy source specifically engineered for the PACSystems RX3i backplane. This module excels in high-availability environments by supporting redundant “hot-standby” configurations and load-sharing capabilities. Consequently, engineers can install up to four IC695PSA140 units within a single RX3i universal backplane.⁵ This scalability allows the system to support a higher density of I/O modules than a standard single-source setup while providing robust fault tolerance against individual power supply failures.

Flexible Voltage Output and Signal Integrity

This power supply converts a broad range of input voltages—spanning 85 to 264 VAC or 100 to 300 VDC—into three regulated DC rails required by RX3i modules.⁶ The hardware delivers a maximum of 40 Watts total output, distributed across +5.1 VDC and +3.3 VDC for internal logic, alongside a dedicated +24 VDC relay power circuit. To protect against transient power drops, the IC695PSA140 features a 20-millisecond holdup time. This “ride-through” capability ensures that the PLC remains operational during brief electrical interruptions, preventing unnecessary system resets and downtime.⁷

Integrated Safety and Diagnostic Monitoring

Safety and diagnostics are central to the IC695PSA140’s design. The module includes sophisticated overcurrent protection, limiting the 5.1 VDC output to 7 Amps and the 3.3 VDC output to 10 Amps to prevent hardware damage.⁸ For real-time monitoring, the front panel features four distinct LED indicators that signal Power, System Fault, Overtemperature, and Overload conditions.⁹ These visual cues allow maintenance teams to identify thermal or electrical stressors immediately. Furthermore, the module occupies two slots on the RX3i backplane, providing a stable mechanical footprint and sufficient surface area for efficient heat dissipation.¹⁰
