The Azbil SDC25 is a compact single-loop digital indicating controller designed for process and temperature control applications.
According to Azbil's official specifications, the SDC25 supports multi-range inputs, including thermocouple, RTD, DC current and DC voltage. It uses PID control and supports different control outputs depending on the exact model configuration. The controller also supports RS-485 communication on applicable configurations.
Important SDC25 features include:
The SDC25 has a 300 ms sampling cycle and specified indication accuracy of ±0.3% FS ±1 digit under stated conditions.
The Azbil SDC36 belongs to the higher-performance C35/C36 controller family.
Azbil specifies the C35/C36 series with ±0.1% FS accuracy and a 100 ms sampling cycle, making it suitable for applications requiring faster control response. It supports multi-range inputs and a variety of control/output configurations.
Depending on the exact model/configuration, the SDC36 platform can provide:
This makes the SDC36 useful in many industrial process-control and machinery automation systems where accurate and responsive regulation is required.
These controllers are designed for industrial process/temperature-control applications. Depending on the equipment design and exact controller configuration, this type of controller can be encountered in control systems involving:
temperature control, process control, heating systems, machinery control, boiler/burner-related control panels, industrial automation panels and other process equipment.
For marine applications, buyers should always match the full model code, input/output configuration, power supply and existing wiring/application before replacement.
At SM MARINE SERVICE™, customers can send us the existing controller's front photo, side/rear nameplate and complete model number, and we can check the available replacement unit.

The most visible difference is their physical/front-panel format, but technically they also belong to different controller families.
The SDC25 / C25 is a compact controller with a 300 ms sampling cycle and ±0.3% FS class accuracy, while the SDC36 / C36 family provides higher-speed 100 ms sampling and ±0.1% FS accuracy according to Azbil specifications.
Therefore, an SDC25 and SDC36 should not automatically be treated as interchangeable. The complete model specification should be checked before replacement.
This is particularly important for buyers in 2026.
Azbil's current product information states that order acceptance for the C25/C26 and C35/C36 series is scheduled to end in September 2026. Azbil identifies C2A/C2B as alternatives to C25/C26 and C3A/C3B as alternatives to C35/C36.
So vessels, factories and service companies maintaining equipment fitted with existing SDC25 or SDC36 controllers may increasingly need existing-model replacement stock or assistance identifying an appropriate successor.
SM MARINE SERVICE™ can support inquiries for existing Azbil controllers as well as other marine and industrial automation components.
Many buyers may also search older automation equipment using the Yamatake name. Therefore, customers looking for older Yamatake/Azbil controllers are welcome to send their requirement.
We can assist with inquiries involving:
Availability varies between New, Used, Tested and Reconditioned equipment depending on the particular product.
When requesting a replacement, please send:
Manufacturer: Azbil / Yamatake
Existing Model: SDC25 / SDC36 or other model
Complete Model Code: From the side/rear nameplate
Quantity Required:
Condition Required: New / Used / Reconditioned
