Description
GE IC695PSD040 Technical Specifications:
- Input Voltage: 24 VDC nominal.
- Input Voltage Range: Typically 18 to 30 VDC (verify specific datasheet for exact tolerances).
- Output Power: 40 Watts total across all backplane rails.
- Output Rails: +3.3 VDC, +5.1 VDC, and +24 VDC Relay.
- Slot Occupancy: Two (2) slots.
Functional Features:
- DC Optimization: Designed specifically for 24VDC control cabinets, eliminating the need for AC-DC conversion inside the PLC rack.
- Battery Backup Compatibility: Ideal for systems requiring uninterrupted power during AC mains failures.
- Diagnostic LEDs: Identical 4-LED diagnostic panel (Power, Fault, Over Temp, Overload) as the AC variant.
- Electronic Protection: Overcurrent and short-circuit protection with automatic recovery.
Application Scenarios:
- Safety instrumented systems (SIS) powered by 24VDC battery banks.
- Remote telemetry and pipeline monitoring stations.
- Mobile equipment and heavy machinery control panels.
- Facilities utilizing centralized 24VDC power distribution.
Performance Parameters:
- Efficiency: High-efficiency DC-DC conversion minimizing heat generation within the control panel.
- Ripple & Noise: Ultra-low output ripple to ensure clean power for sensitive analog I/O modules.
Material Composition & Structural Characteristics:
- Enclosure: Standard RX3i 2-slot power supply housing.
- Terminals: Heavy-duty screw terminals rated for continuous 24VDC current draw.
- Internal Topology: High-frequency DC-DC buck/boost converter circuitry.
Working Principle: The module steps down or regulates the incoming 24VDC supply to the required internal backplane voltages (+3.3V, +5.1V, and isolated +24V). It utilizes solid-state switching regulators to maintain tight voltage tolerance despite fluctuations in the primary 24VDC source.
Installation Requirements:
- Polarity Protection: Strictly observe positive and negative terminal markings. Reverse polarity can cause catastrophic failure.
- Wire Sizing: Use adequately sized DC cabling to prevent voltage drop over long distances from the power source to the PLC rack.
Usage Precautions:
- Non-Interchangeability: Do not substitute an AC-input power supply in a system wired exclusively for DC, and vice versa.
- Fuse Protection: Install an appropriately rated DC circuit breaker or fuse on the incoming 24VDC line to protect the facility wiring.
- Grounding: Ensure the 24VDC common is properly grounded according to system grounding architecture.
