GE IC695PSD040B PACSystems RX3i Power Supply Module
Configured for high-efficiency DC power delivery in PACSystems RX3i backplane racks, the GE IC695PSD040B (IC695PSD040 Power Supply Module) provides direct physical/electrical execution. This hardware unit generates regulated internal bus voltages from an AC line input to sustain logic processing, I/O bus communications, and field-side relay drive loops across local and expansion rack setups.

Backplane Bus & Power Allocation Dynamics
The IC695PSD040B delivers triple-voltage DC rails directly to the PACSystems RX3i backplane bus. Internal power conditioning circuits convert incoming 85-264 VAC supply lines into high-density +5 VDC (4 A) and +3.3 VDC (3 A) logic supplies alongside a localized +24 VDC (0.5 A) isolated relay bus. System configuration software verifies total backplane current draw prior to deployment to prevent voltage drop across high-density digital I/O arrays. Thermal dissipation profiles remain optimized through internal heatsink conduction, ensuring system firmware stability across deterministic Ethernet and backplane communication paths without active fan cooling.
Frequently Asked Questions
Q: Can the IC695PSD040B power supply module be hot-swapped during rack operation?
A: No. Installing or removing the IC695PSD040B while the AC main power line is energized causes electric arc risk and disrupts the backplane logic bus. Power down all incoming 120/240 VAC supply lines before insertion or extraction.
Q: What limits apply to the +24 VDC output bus provided by this module?
A: The onboard +24 VDC relay bus supplies a maximum current of 0.5 A. External power supplies must drive field actuators or heavy relay loads exceeding this threshold to avoid triggering internal thermal shutdown or overcurrent protection circuits.
Q: Is it permissible to parallel two IC695PSD040B modules in a single RX3i backplane for power redundancy?
A: No. The standard RX3i universal backplane supports only one power supply module per rack section. Load expansion requires an additional expansion backplane populated with its own dedicated power supply unit.
Field Installation Guidelines
Mounting and wiring of the IC695PSD040B must occur in de-energized conditions. Seat the module firmly into the dedicated power supply slot on the far left of the RX3i universal backplane until the rear connector latches engage fully. Fasten the captive retaining screw at the top of the module to guarantee physical grounding through the DIN-rail / panel chassis backplate.
Incoming 120/240 VAC supply conductors must pass through dedicated terminal block screws. Maintain a physical separation of at least 50 mm between AC power input cables and low-voltage DC I/O signal lines to limit high-frequency electromagnetic noise coupling. Strip conductor insulation strictly to manufacturer length specifications to avoid bare wire exposure. Connect the protective earth (PE) terminal directly to the central cabinet ground busbar using a low-impedance conductor with a minimum engagement torque compliant with standard panel assembly practices.
