Yokogawa SDV144-S63 Digital Input Module
Overview
Yokogawa SDV144-S63 is a digital input module for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). The module can be installed in a Safety Node Unit or a Safety Control Unit and is used to receive field switch/contact signals. The module is classified as a safety-critical input module. The suffix code "S" indicates the standard type, "6" indicates the presence of a signal line interface adapter without explosion-proof capability, and "3" indicates compliance with the ISA G3 standard.
🚀Fuction & features
- Withstand voltage rating: When the SDV144-S63 is connected to the SED4D terminal board using a dedicated signal cable, the withstand voltage is 500 V AC (*5). If a MIL connector cable is used, the withstand voltage depends on the cable specifications.
- Field wiring diagnostics: When used with the SCB100 (open-circuit detection, normally closed signal) and the SCB110 (short-circuit detection, normally open signal), the SDV144-S63 enables channel-level open-circuit and short-circuit fault detection. To detect both open-circuit and short-circuit conditions simultaneously, the configuration requires a combination of "SCB100 connected in parallel + SCB110 connected in series."
- Channel restrictions: The number of available channels and power supply may be limited for SDV144-SC models (*3).

Questions & Answers
💡 FAQ
Q: What is the brand?
A: Yokogawa
Q: In which industrial fields is the SDV144-S63 used?
A: Safety interlock circuits: Emergency stop pushbuttons, safety door switches, high-high/low-low level alarm contacts.
Fire and gas detection systems: Alarm outputs from flame detectors and gas detectors.
Equipment status monitoring: Pump running status and valve limit switches.
Q: What does the "S63" suffix represent? Are there other models?
A:The suffix represents a specific specification code. The SDV144 series has multiple sub-models, such as S1, S2, S3, and so on.
Q: What is the withstand voltage of the SDV144-S63 module?
A: The withstand voltage is not fixed and depends on the secondary-side voltage rating to ground of the field power supply and the connected cables:
- If the secondary-side voltage rating to ground of the field power supply is lower than the module's nominal value, the voltage rating of the power supply applies.
- When using the dedicated signal cable (AKB331), the withstand voltage between the input signal lines and the system is 500 V AC.
- When using MIL connector cables, the withstand voltage depends entirely on the electrical specifications of the selected cable and must be verified separately.
Q: What is the payment method?
A: T/T
