Compatible Replacement & Equivalent Models
When the original AD5*D is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system configuration:
- YOKOGAWA AD51D – Direct sub-variant; confirm channel count and connector type
- YOKOGAWA AD52D – Alternative sub-variant for specific I/O module pairings
- YOKOGAWA AD53D – Higher-density termination option within the same series
- YOKOGAWA AMM12D / AMM22D Terminal Boards – For analog multi-point applications in CENTUM VP
- Third-party DIN-rail terminal boards – Phoenix Contact, Weidmüller, or Wago equivalents may be adapted with custom wiring harnesses (engineering review required)
⚠ Important: Always verify connector pinout, signal type, and module compatibility before substituting. Contact Konmask engineering support for a validated replacement recommendation.
Why Choose the Original Model
- Guaranteed compatibility – Designed and tested specifically for YOKOGAWA CENTUM DCS I/O modules
- Signal integrity – Factory-calibrated termination points minimize noise and signal loss
- Reduced commissioning risk – Plug-and-play with existing YOKOGAWA field wiring infrastructure
- Long-term support – YOKOGAWA spare parts ecosystem with documented revision history
- Regulatory compliance – Meets industrial safety and EMC standards required in process industries
Typical Applications
- Oil & gas process control panels (upstream/downstream)
- Chemical and petrochemical plant DCS field termination cabinets
- Power generation and utilities control rooms
- Pharmaceutical manufacturing automation systems
- Pulp, paper, and food & beverage process lines
- Water treatment and environmental monitoring systems
System Compatibility
| YOKOGAWA CENTUM CS | ✅ Compatible (verify sub-revision) |
| YOKOGAWA CENTUM CS 3000 | ✅ Compatible |
| YOKOGAWA CENTUM VP | ✅ Compatible (confirm I/O module pairing) |
| YOKOGAWA ProSafe-RS | ⚠ Consult datasheet – safety system requirements apply |
| Third-party DCS / PLC systems | ❌ Not directly compatible – custom adaptation required |
Selection Guide
Use the following criteria to determine whether the AD5*D is the right terminal board for your application:
- Step 1 – Identify your I/O module: Confirm the YOKOGAWA I/O module model number (e.g., AAI141, AAI543) that the terminal board will connect to.
- Step 2 – Match the sub-revision: The AD5*D wildcard covers multiple sub-variants (AD51D, AD52D, etc.). Match the suffix to your module’s required termination type.
- Step 3 – Verify channel count: Confirm the number of I/O channels required (8-ch, 16-ch, 32-ch configurations may differ).
- Step 4 – Check cabinet space: Confirm DIN rail or panel mounting dimensions match your marshalling cabinet layout.
- Step 5 – Confirm signal type: Analog (4–20 mA, thermocouple, RTD) vs. digital (24 VDC, relay) termination boards are not interchangeable.
- Step 6 – Source with documentation: Request the YOKOGAWA part datasheet and revision certificate when ordering from Konmask.

Replacement & Compatibility FAQ
Q: Can I use a third-party terminal board instead of the YOKOGAWA AD5*D?
A: In some cases yes, but it requires engineering validation of pinout, signal type, and module compatibility. We recommend using the original or a verified YOKOGAWA equivalent to avoid commissioning issues.
Q: What does the asterisk (*) in AD5*D mean?
A: The * is a wildcard representing sub-variants in the AD5xD series (e.g., AD51D, AD52D, AD53D). Each sub-variant is paired with a specific I/O module. Confirm your exact module number before ordering.
Q: Is the AD5*D still in production?
A: YOKOGAWA periodically updates its product lifecycle status. Contact Konmask to confirm current availability, lead time, and whether a recommended successor model exists.
Q: Do you provide a warranty?
A: Yes. All parts come with Konmask’s sourcing guarantee. Warranty terms vary by product condition (new, refurbished, surplus). Contact us for details.
Q: Can you ship internationally?
A: Yes. We ship worldwide with DHL, FedEx, and UPS. Export documentation and customs support available for regulated items.
