Product Description
Product Overview
The Yokogawa SDV144-S63 S4 Digital Input Module is a robust and versatile component designed for Yokogawa’s industrial control systems, such as CENTUM VP or ProSafe-RS platforms. This module accepts 16 no-voltage contact signals from field devices, with module isolation and dual-redundant configuration capability for enhanced reliability. Operating with a 24 V DC external power supply, it features a maximum input response time of 40 ms and a withstand voltage of 2 kV AC. Weighing approximately 0.36 kg (or 0.41 kg with a signal cable interface adapter), it supports flexible connection options including pressure clamp terminals, MIL cables, or dedicated signal cables (AKB331), and includes ISA Standard G3 compliance for operation in temperatures from -20 to 70°C.

Specific Configuration
- Model/Part Number: SDV144-S63 S4
- Configuration Details:
- Suffix Codes: -S (Standard type), 6 (With signal cable interface adapter and no explosion protection), 3 (With ISA Standard G3 and temperature -20 to 70°C)
- "S4" is not explicitly listed in suffix codes; may be a typo (intended as "-S63") or an undocumented variant
Additional Notes
- The "SDV144-S63 S4" is a Digital Input Module with 16 isolated channels for no-voltage contact signals, designed for integration into Yokogawa’s FCS or safety systems, supporting dual-redundancy for critical applications.
- Suffix codes "-S63" indicate a standard type (-S) with a signal cable interface adapter (-6) and ISA Standard G3 compliance with a -20 to 70°C temperature range (-3); "S4" may be a typo for "-S63" or an undocumented variant, treated here as part of the configuration based on prior submissions (e.g., SDV144-S63PRP S4).
- "External power supply: 24 V DC +20% / -10%" calculates to 21.6 V to 28.8 V DC, with a 200 mA capacity, supporting field device powering.
- Weight options "Approx. 0.36 kg" and "0.41 kg" reflect different connection types; converted to 0.36 kg (0.79 lb) and 0.41 kg (0.90 lb); "-6" suffix (signal cable adapter) aligns with the heavier 0.41 kg.
- Limited prompt data restricts additional specs (e.g., dimensions, specific options like /PRP); the -20 to 70°C range from suffix -3 is confirmed, but other details require datasheet verification. Prior submission (SDV144-S63PRP S4) included /PRP, not specified here.
