Features:

  • Provides 16 isolated inputs for safety system applications.
  • Enables high-availability configurations for critical safety loops.
  • Supports pressure clamp, MIL cable, and AKB331 signal cable.
The SDV144-S53 S4 provides 16 digital input channels with module isolation for safety system applications in ProSafe-RS environments. It accepts no-voltage contact signals from field devices such as limit switches, pushbuttons, and safety relays. The SDV144-S53 S4 has an input current of 6mA at 24V DC and a response time of 40ms maximum. The module isolation ensures electrical separation between input signals and the system, enhancing safety and noise immunity in critical applications.

The SDV144-S53 S4 can be configured in dual-redundant configurations for critical safety applications where high availability is essential. This redundancy ensures continued operation if one module fails, maintaining safety integrity in demanding process environments. The SDV144-S53 S4's dual-redundant capability makes it suitable for use in emergency shutdown systems, fire and gas detection, and burner management systems where fault tolerance is paramount.

The SDV144-S53 S4 supports multiple external connection options including pressure clamp terminals, MIL cable, and dedicated AKB331 signal cable. The module supports SCB100 and SCB110 connection units for normally off and normally on input configurations, enabling line supervision for short and open circuit detection. The SDV144-S53 S4 is available with ISA Standard G3 and temperature options (-20°C to 70°C), explosion protection, and high-density installation configurations.

The SDV144-S53 S4 YOKOGAWA 16-Channel Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Emergency Shutdown Systems (ESD): Monitors critical process triggers—such as emergency stop buttons, high-pressure switches, and pipeline limit switches—to execute automated, safe machinery shutdowns.
  • Fire and Gas Systems (FGS): Acquires signals from flame detectors, toxic gas sensors, and smoke alarms to initiate deluge systems, activate alarms, or trigger ventilation isolation.
  • Burner Management Systems (BMS): Monitors boiler and furnace parameters (e.g., fuel valve positions, flame scanners, air pressure switches) to guarantee safe ignition, operation, and fuel trip sequences.
  • Critical Process Control: Widely used across highly volatile petrochemical plants, offshore oil & gas rigs, chemical refineries, LNG terminals, and nuclear or thermal power generation facilities.
  • Functional Safety Standards: Certified by TÜV Rheinland in accordance with IEC 61508 (Parts 1–7) and IEC 61511 for direct implementation in SIL3 safety loops.
  • Marine Approvals: Certified under various maritime classification societies (such as ABS, DNV, and BV) for installation on marine vessels and floating offshore production units (FPSOs).
  • Electrical Safety & Radiated Interference: Carries CE Marking, UKCA, and compliance under EMC Directive standards (IEC/EN 61000-6-2 for industrial immunity and IEC/EN 61000-6-4 for emissions).
  • Safety Control Unit Integration: The module mounts directly onto Yokogawa SSC60S, SSC60D, SSC50S, or SSC50D Safety Control Units via regional safety bus networks.
  • DCS Interoperability (CENTUM Integration): While operating as a fully autonomous safety controller, the module bridges data seamlessly to Yokogawa's CENTUM VP / CENTUM CS 3000 DCS networks. This allows standard plant operators to view safety alarms, sequence-of-events (SOE) logs, and diagnostics directly on the main DCS Human-Machine Interface (HMI) without complex third-party protocol mapping.
  • Terminal Board Compatibility: It supports connection to pressure clamp terminal blocks or MIL cable connection boards. It pairs natively with specialized field connection cables (like the AKB331 series signal cables) to ensure noise-free signal delivery from field sensors.
