Product Overview

The IC695PSD140E is a dedicated expansion power supply for the PACSystems RX3i series. This module powers I/O and communication modules in remote or expansion bases, converting a 24 VDC nominal input into the necessary internal bus voltages. It ensures stable, factory-certified power for distributed I/O systems. Supplied in 100% Brand New condition, the IC695PSD140E is engineered for reliable operation in remote environments.

Technical Specifications

Key Features

• Optimized for Remote I/O: Powers remote expansion racks to avoid voltage drop over long cable runs.

• Flexible DC Input: Wide input range (18V to 30V) supports industrial battery systems and fluctuating DC sources.

• Compact Thermal Profile: High-efficiency conversion minimizes heat generation for reliable operation in non-ventilated enclosures.

• Deterministic Power Delivery: Ensures stable power to remote I/O modules, even during fluctuations in the primary DC source.

• Seamless Expansion Integration: Installs directly in the expansion backplane, powering connected modules without complex wiring.

FAQs

Can I use the IC695PSD140E in the same rack as the CPU?
No, this module is for expansion racks only. The main CPU rack requires a universal power supply (e.g., IC695PSA040 or IC695PSD040).

What does the "E" version signify?
The "E" revision includes updated components for improved reliability and manufacturing compliance, while maintaining full compatibility with the IC695PSD140 series.

How do I calculate if 40 Watts is enough for my expansion rack?
Sum the current requirements (at 5.1V and 3.3V) for all modules in the expansion rack. If the total exceeds 40W, an additional power supply is needed.

Does this module support redundancy?
No, the IC695PSD140E does not support redundancy. For redundant power configurations, use models like IC695PSD140 or PSA series.
