GE IC695PSD040 Power Supply Module: Technical Specs & Review
GE IC695PSD040 Power Supply Module: Technical Specs & Review
The GE IC695PSD040 is a power supply module designed for the PACSystem RX3i platform, currently under Emerson Automation. This module provides reliable DC power to the backplane and supports various output voltages essential for industrial automation systems. In this review, we examine its key specifications, installation requirements, and practical considerations for engineers.
Key Specifications
- Input voltage range: Start 18-30 VDC; Run 12-30 VDC
- Maximum input power: 60 Watts at full load
- Output power: 40 Watts maximum
- Output voltages: 5.1 VDC, 3.3 VDC, and 24 VDC (auxiliary)
- Output currents: 5.1 VDC at 0-6 Amps; 3.3 VDC at 0-9 Amps
- Ride-through time: 10 ms
- Inrush current: 4 Amps for 100 ms maximum
- LED indicators: Power, P/S Fault, Overtemperature, Overload
- On/Off switch: Yes
- Wiring: 14 AWG to 18 AWG
- Slot assignment: Slot 0 on RX3i universal backplane
Output Capabilities
The module delivers three distinct output voltages. The 5.1 VDC and 3.3 VDC outputs power the backplane and connected modules. The 24 VDC output can energize relay output module circuits. Total output power must not exceed 40 Watts, with each output limited to 30 Watts maximum. The output current for 5.1 VDC ranges from 0 to 6 Amps, and for 3.3 VDC ranges from 0 to 9 Amps. The nominal rated input voltage is 24 VDC.
Installation and Compatibility
The GE IC695PSD040 mounts to an RX3i universal backplane in Slot 0. Only one module per backplane is required. This module does not support redundant power supply or increased capacity modes. However, it supports daisy chaining of up to two PSD040 units, but this does not increase total output capacity. If the rack power demand exceeds 40 Watts, install additional modules on a separate backplane to manage loading. The module has no isolation and a ripple of 50 mV.
Practical Considerations
The 10 ms ride-through time allows the IC695PSD040 to maintain output during brief power disturbances, minimizing downtime. The on/off switch provides manual control, and the four LED indicators give immediate status on power, fault, overtemperature, and overload conditions. The CPU directly connects to these indicators to detect power loss and react accordingly. Engineers should account for the 4 Amp inrush current when sizing upstream protection. Use 14 AWG to 18 AWG wiring for terminal connections. Terminal current is rated at 6 Amps.
Conclusion
The GE IC695PSD040 offers a robust power solution for PACSystem RX3i racks. Its multiple outputs and clear status indicators simplify integration and troubleshooting. Engineers should consider its power limitations and lack of redundancy when designing critical systems. Overall, this module remains a reliable choice for standard backplane power needs in industrial automation environments.
