Technical Overview

The ADV144-S13 is a high-versatility digital input module for the Yokogawa CENTUM VP DCS, designed to capture 16 discrete DC signals across a wide voltage range of 24 V to 250 V DC. Its broad input capability allows it to consolidate multiple DC voltage standards into a single module, reducing the need for multiple types and external converters.

Each channel is fully isolated, providing high-level electrical protection and compatibility with dual-redundant I/O configurations for high availability in critical process environments.

Technical Specifications

Strategic Applications

• Power Substation Monitoring: Direct interface with 110V or 220V DC battery-backed switchgear and breaker statuses.

• Large-Scale Refining: Consolidates 24V instrument loops and 125V DC motor control signals into a single I/O rack.

• Safety Feedback Loops: Redundant status monitoring for high-voltage DC interlocks.

• Remote Terminal Units (RTUs): High-density interface for legacy field equipment with non-standard DC voltages.

Engineering FAQ

What is the primary advantage of the wide-range input?

• Allows hardware standardization across 24V, 48V, 110V, and 220V DC systems, reducing spare parts inventory and simplifying engineering design.

Can this module handle 250V AC signals?

• No. The ADV144-S13 is DC-only. For AC signals (100–240V AC), use ADV141 or ADV142 modules to ensure proper detection and hardware safety.

Is any configuration required to recognize different DC voltages?

• No. The module uses adaptive threshold logic to detect DC presence across 24–250 V DC. It is effectively plug-and-play for various field voltages.
