Product Description

The Yokogawa SDV144-S13/B4D10 is a high-integrity 16-channel digital input module designed for the ProSafe-RS Safety Instrumented System (SIS). It monitors critical safety devices, including emergency shutdown (ESD) switches and process sensors, providing millisecond-level accuracy required for SIL 3 safety loops.

This S13 configuration is built for harsh industrial environments, featuring ISA Standard G3 corrosive gas resistance. The B4D10 suffix denotes a MIL-connector signal cable interface, optimized for use with dedicated safety terminal boards, ensuring secure, high-density connections. With individual channel isolation, this module prevents electrical faults from propagating, maintaining maximum system reliability and uptime.

Technical Specifications

Application Scenarios

The SDV144-S13/B4D10 is ideal for oil & gas, petrochemical, and power generation facilities, where monitoring field-side safety interlocks is critical. Its ruggedized design and corrosion-resistant construction allow reliable signal acquisition in environments with hazardous gases like $H_{2}S$, ensuring functional safety even under extreme conditions.

Technical FAQ

What does the B4D10 suffix specify?
The B4D10 code defines the module’s connection style and hardware revision, optimized for MIL-spec signal cables (e.g., AKB331) to interface with safety terminal boards.

Is this module compatible with standard CENTUM VP I/O nests?
No. The SDV144 series must be installed in a ProSafe-RS safety node. While it communicates status to the CENTUM VP HMI, all safety logic is executed within the safety controller to maintain SIL 3 compliance.
