GE IC695PSD040-F

  • Product Introduction: This is a dedicated 4-slot power supply module for the GE VersaMax PLC platform. The “040” indicates a 4-slot chassis with 4A current capacity. The “F” suffix denotes a specific firmware or feature variant (often related to fault reporting or input voltage range). This module combines the chassis and power supply in one unit, providing a compact solution for small VersaMax systems. It delivers 24VDC (or 5VDC depending on configuration) to the backplane bus, powering up to 4 I/O modules. It is ideal for small machines, standalone controllers, and applications where a full-size rack is unnecessary.

    • DIN-rail mountable with included brackets
    • Grounding lug for chassis earth
  • Working Principle:
    • AC mains enters the terminal block and is rectified by a bridge rectifier. The DC is filtered and fed into a high-frequency switching regulator (typically 80-100kHz). The regulator produces a stable 24VDC output for the I/O backplane and a 5VDC output for logic. An opto-isolated feedback loop monitors the 24V output and adjusts the PWM duty cycle to maintain regulation. The power good circuit compares the output voltage to a reference and enables the backplane drive only when voltage is within 22-28VDC. The 4 slots share the 4A current budget — the module limits total current to protect itself.
  • Installation Requirements:
    • Mount on DIN-rail or panel
    • Connect 120/240VAC to the rear terminal block (verify voltage setting)
    • Ground the chassis to building earth
    • Install I/O modules in any of the 4 slots
    • Do not exceed 4A total bus current — calculate module consumption (typical digital module = 100-300mA, analog = 200-500mA)
    • Ensure adequate ventilation — do not enclose in a sealed box
  • Usage Precautions:
    • Verify AC input voltage (120V vs 240V) before powering up — wrong setting destroys the module
    • Total current must not exceed 4A — use external 24VDC supply if more current is needed
    • Do not block the heat sink fins — overheating causes thermal shutdown
    • Check Power Good LED before inserting CPU or critical modules
    • Do not hot-swap I/O modules — power down first
    • For 4 slots fully loaded with high-current modules, verify total consumption is under 4A (typical max: 4 x 500mA = 2A, well within limit)
