Description
The
SDV144-S13 is a 16-channel digital input module with module isolation, designed for industrial applications requiring stable signal processing. It accepts no-voltage contact signals (1 kΩ max on-resistance, 100 kΩ min off-resistance) and operates on a 24 V DC external power supply (±20% tolerance). Its compact design (0.36 kg) and compliance with ISA G3 standards (temperature range: -20°C to 70°C) enable operation in corrosive and extreme temperature environments. The module is discontinued and replaced by the
SDV144-S53, but remains a trusted choice for legacy systems.

SDV144-S13
- High Reliability: Module isolation and noise protection ensure accurate signal processing in harsh environments.
- Wide Compatibility: Supports 24 V DC systems with ±20% voltage tolerance, suitable for diverse industrial setups.
- Compact Design: Lightweight (0.36 kg) and space-efficient, ideal for dense control panels.
- Legacy Support: Backward-compatible with Yokogawa’s ProSafe-RS and Centum VP systems, ensuring continuity for existing installations.
- Environmental Resilience: Meets ISA G3 standards for corrosion resistance and operates across a broad temperature range.
- Industries: Manufacturing, energy, chemical processing, and automation systems.
- Scenarios: Monitoring pump status, valve positions, and sensor inputs in DCS.
- Case Study: A chemical plant used the SDV144-S13 to monitor 16 safety switches in a corrosive environment. The module’s ISA G3 compliance and 2 kV isolation prevented signal interference, ensuring reliable safety system operation.
Compared to similar digital input modules, the SDV144-S13 offers superior noise isolation (2 kV AC) and a broader temperature range (-20°C to 70°C), outperforming standard modules limited to 0–50°C. Its modular design and backward compatibility with Yokogawa systems reduce integration costs for legacy upgrades.
SDV144-S13
- Compatibility: Ensure integration with Yokogawa DCS (ProSafe-RS, Centum VP).
- Environment: Choose the module for corrosive settings (ISA G3) or extreme temperatures.
- Budget: Consider the replaced model SDV144-S53 for new projects; the SDV144-S13 is ideal for maintaining legacy systems.
- Installation: Verify external power supply (24 V DC) and contact rating (24 V DC ±20%, 10 mA min).
- Safety: Follow voltage limits (max 30 V DC instantaneous).
- Maintenance: Regularly inspect terminals for corrosion (ISA G3 environments).
- Installation: Use approved connectors (pressure clamp, MIL cable, or AKB331 signal cable).
- Redundancy: For critical systems, pair with dual-redundant terminal blocks (e.g., STB4D-00).
