IC695PSD140 GE PACSystems RX3i Power Supply 40W DC Input Module

Technical Engineering Brief

• The IC695PSD140 is a high-performance multipurpose power supply module for the PACSystems RX3i platform.
• Engineered for critical infrastructure, this module facilitates both load-sharing and redundant power architectures.
• It accepts a dedicated input range of 18 to 30 VDC and delivers three regulated output voltages to the backplane.
• The IC695PSD140 features a 20ms ride-through capability to maintain system stability during transient voltage drops.

Global PLC Spare HUB's Insight

• Our technical team highlights the IC695PSD140 as a cornerstone for high-availability industrial systems.
• Unlike standard modules, this unit allows up to four supplies to reside on a single RX3i universal backplane.
• The "multipurpose" design enables engineers to scale power capacity as I/O density increases within the chassis.
• Critical Note: This module is strictly incompatible with PSD040 or PSA040 models in redundant modes to prevent hardware damage.

Selection Guide & FAQ

• Selection Advice: Calculate total I/O wattage on the 5.1V and 3.3V rails to ensure it stays under 40W per module.
• Selection Advice: Ensure all redundant IC695PSD140 units are wired to the same primary power source.

• Question: Can I toggle the front-panel On/Off switch during live operation?
• Answer: Only if you have a redundant setup; turning off a non-redundant module will cause an immediate CPU shutdown.

• Question: What happens if I mix this with an IC695PSA040 in a redundant rack?
• Answer: This is strictly prohibited; mixing these different power supply types can cause physical damage to both modules.

• Question: Does the IC695PSD140 provide electrical isolation?
• Answer: This specific module does not provide isolation between the input power and the backplane.

• Question: Why is the 20ms ride-through time important for my facility?
• Answer: It acts as a buffer against brief voltage sags, preventing the PLC from rebooting during minor power fluctuations.

• Question: Is a terminal block included for field wiring?
• Answer: Yes, the module comes with the necessary terminal assembly for #14-22 AWG wiring.
