Yokogawa S9758UV Centum VP 24V Power Cable for AEP7D-4 S9758UV

S9758UV Yokogawa DCS Power Supply Cable (AEP7D-4 Compatible, 24 V DC, 2 m)

Oiltech Controls’s Insight

• Our engineering review confirms that the Yokogawa S9758UV serves as a vital component in maintaining system power integrity for Centum VP DCS hardware.
• When running dual redundant 24 V DC power buses, voltage drop and physical connection reliability are critical.
• The S9758UV cable features heavy-duty, industrial-grade copper conductors designed to handle the high-current demands of a fully populated AEP7D-4 unit without overheating.
• Because one end is raw and unterminated, site technicians can easily trim the 2-meter length to eliminate unnecessary slack inside high-density marshalling cabinets, reducing EMI loop capture risk.

Equipment Compatibility

• Fits Yokogawa AEP7D-4 horizontal type Primary Power Supply Bus Units.
• Fits Yokogawa AEPV7D-4 vertical type cabinet-mounted Power Supply Bus Units.
• Connects directly to Centum VP 24 V DC system field terminal boards.
• Serves as the primary 24 V feed link from main cabinet breakers to distributed I/O nests.

Technical & Purchasing FAQ

• Question: How do I confirm if my power bus requires the S9758UV instead of the S9756UV or S9757UV?Answer: The S9758UV is specifically designed for 24 V DC AEP7D-4 series units. If your cabinet uses 100-120 V AC (AEP7D-1) or 220-240 V AC (AEP7D-2) power buses, you must use the S9756UV or S9757UV respectively. Always verify the voltage label on the physical module before purchasing.
• Question: Is the pin-to-wire color mapping of the S9758UV identical to the AC cable versions?Answer: No, the wiring schematic differs significantly. For the 24 V DC S9758UV cable, Pin 3 corresponds to Black (Positive), Pin 2 corresponds to White (Negative), and Pin 1 is Green (Ground). Standard AC cables use different mappings to handle Live and Neutral assignments.
• Question: Why does the S9758UV come with one end unterminated?Answer: System integrators prefer this because it allows the cable to be run smoothly through cable glands and narrow wire ducts. You can crimp on the exact ferrule or ring-terminal type required by your specific line-side distribution block.
• Question: What is the current capacity rating for these primary power cables?Answer: The S9758UV cable assemblies are designed to safely support up to the 10 A maximum per-port current rating specified for AEP7D-4 and AEPV7D-4 primary bus units.
• Question: Can we shorten the 2-meter cable if our power distribution block is very close?Answer: Yes, you can cut this cable to your exact desired size. Keep the cuts clean, use high-quality wire strippers, and ensure proper crimping of the terminal pins to maintain minimum contact resistance.
