GE IC695PSD140A DC power module
GE IC695PSD140A
Product Overview
GE IC695PSD140A is a high-performance, high-power-density DC power supply module specifically designed for General Electric (GE)’s PACSystems RX3i Programmable Automation Controller (PAC). Serving as the “power core” in automated control cabinets, this product converts, isolates, and regulates externally input DC power (typically from the main power supply inside the cabinet) to deliver extremely stable and clean +5 VDC logic power and +24 VDC field power to the entire RX3i rack backplane and all installed modules (including CPU, high-density I/O modules, communication modules, etc.). The core value of GE IC695PSD140A lies in its robust output capability, excellent voltage stability, high conversion efficiency, and comprehensive protection functions. It meets the stringent power requirements of large-scale, complex control systems, ensuring that the control system always receives high-quality power supply even when load fluctuates or input voltage changes—thus guaranteeing the absolute continuity of critical automated processes and data integrity.

Structure and Composition
GE IC695PSD140A features a rugged metal housing design, which ensures excellent heat dissipation, mechanical strength, and electromagnetic interference (EMI) shielding performance. Its front panel is equipped with an LED status indicator (usually a green “OK” light) for intuitive display of the power supply’s normal operating status. The module’s interior consists of multiple high-performance functional units:
- The input stage includes a reverse polarity protection circuit and an EMI filter to prevent wiring errors and suppress noise on the input line;
- The high-efficiency DC/DC converter is the core component, adopting advanced switching technology to convert the input 24VDC into isolated, precisely regulated +5.1 VDC and +24 VDC outputs;
- The post-stage filtering and voltage regulation circuits ensure extremely low output ripple and noise.
The module connects closely to the RX3i rack backplane via a multi-pin connector at the rear, enabling efficient power distribution to the backplane bus. Its design emphasizes thermal management, optimizing heat dissipation through the housing and internal layout.
trol, and harsh industrial environments—wherever large-scale, high-availability control systems need to be built—IC695PSD140A is an ideal choice for ensuring uninterrupted power supply to the system.
Installation and Maintenance
Pre-Installation Preparation
Before installing or replacing GE IC695PSD140A, ensure that all input and output power supplies are cut off and that Lockout/Tagout (LOTO) procedures are implemented. Confirm that the cabinet is properly grounded. Check that the polarity of the input DC power supply is correct and that the voltage is within the 19.2-31.2 VDC range. Plan the specifications of the input cables to meet its current requirements.
Maintenance Recommendations
This module requires no regular maintenance. During daily inspections, observe the OK indicator on the front of the module to confirm it is steadily lit. Ensure that the module’s ventilation and heat dissipation paths are unobstructed and free from dust blockage. If the system malfunctions, before troubleshooting other modules, measure whether the +5VDC voltage on the backplane is stably within the range of 5.1V ± 0.5%. Due to its high reliability, the module itself has an extremely low failure rate; if a fault is confirmed, direct replacement is recommended.
