Engineered specifically for legacy CV-series backplane architectures, the Omron CVM1-PA208 supplies reliable, low-noise DC control power directly to the rack's system buses. This high-capacity power module accepts a wide AC input range and converts it to a highly stable 5 VDC, 8 A output, which is crucial for maintaining processor integrity and preventing backplane communication errors. The unit is optimized for heavy-duty industrial configurations where PLC modules require consistent current supply without voltage sags.
| Parameter | Specification |
|---|---|
| Manufacturer | Omron |
| Model Number | CVM1-PA208 |
| Input Voltage | 100 to 120 VAC / 200 to 240 VAC (selectable) |
| Frequency Rating | 50 / 60 Hz |
| Output Voltage | 5 VDC |
| Output Current | 8 A |
| Power Consumption | 150 VA |
| Operating Temperature | 0 to 55 degC (32 to 131 degF) |
| Country of Origin | Japan |
| Shipping Weight (Calculated) | 1.50 kg |
| Package Dimensions (Calculated) | 24.5 x 14.0 x 9.5 cm |
| Terminal Label | Function / Circuit Assignment |
|---|---|
| AC100-120V / AC200-240V | Main AC line power supply input terminals. |
| LG | Line ground (noise filter ground) to reduce common-mode high-frequency interference. |
| GR | Frame Ground terminal connected directly to the system grounding bar. |
| RUN OUT | Relay contact terminals (SPST-NO) that close when the CPU is operating normally. |
The CVM1-PA208 power supply replaces standard or lower amperage modules within the CV family (such as 3 A and 5 A variants) to support system expansions containing high-density digital or analog cards. When updating backplane hardware, verify that total current consumption on the 5 VDC internal bus does not exceed the unit's 8 A output ceiling.
Overheating in sealed, non-ventilated enclosures can lead to accelerated aging of the internal smoothing capacitors. Keep a minimum vertical spacing of 20 mm around the rack power unit to allow convective cooling. If output voltage drops below 4.75 VDC, the system watchdog will trip, halting PLC execution as a safety precaution.
Ensure that the Line Ground (LG) and Frame Ground (GR) terminals are wired correctly. Loop the GR terminal with a heavy, low-impedance ground strap directly to your panel plate. Leaving the GR terminal disconnected or sharing a daisy-chained ground with high-noise variable frequency drives (VFDs) can introduce electromagnetic interference, causing intermittent CPU memory corruptions.
Disconnect all incoming AC electrical power sources before handling, mounting, or wiring the terminal block. Touch hazards exist at input terminals when line power is applied. Verify the absence of voltage with a properly calibrated multimeter prior to starting system integration.
