Product Description
The SDV144-S13/B4D00 (SDV144) is a high-reliability, 16-channel digital input module designed for Yokogawa’s ProSafe-RS Safety Instrumented System (SIS). Unlike standard control modules, it is engineered for functional safety, monitoring critical inputs such as emergency stop buttons, flame detectors, and pressure switches.
The S13 configuration provides ISA Standard G3 corrosive gas protection, while the hardware revision is optimized for Vnet/IP communication. The B4D00 option equips the module with a MIL-spec interface, allowing connection to dedicated terminal blocks via AKB331 cables for secure, vibration-resistant safety-critical data transmission.

Application Scenarios
The SDV144-S13/B4D00 is a core module for Safety Instrumented Systems (SIS) in oil & gas, petrochemical, and power generation industries. It is typically deployed in SIL-rated applications where timely detection of signal changes is critical to prevent hazardous events. Its G3 rating ensures reliable operation in environments with corrosive gases such as sulfur or chlorine, making it suitable for offshore platforms, refineries, and chemical plants.
Technical FAQ
Is this module compatible with CENTUM VP?
While it operates on the same network fabric, the SDV144 executes safety logic independently within ProSafe-RS. It can provide status information to CENTUM VP HMI for monitoring, but all safety decisions are handled internally.
What does the B4D00 suffix signify?
The B4D00 denotes a MIL-spec connector interface for the module. It requires a compatible signal cable, typically AKB331, instead of conventional screw terminals, ensuring secure, vibration-resistant connections for critical signals.
