High-Voltage Wide-Range Input for CENTUM VP Systems

The ADV144-S13 digital input module provides 16 isolated DC input channels for Yokogawa CENTUM VP and CS 3000 distributed control systems. This module accepts a remarkably wide voltage range from 24 V to 250 V DC, consolidating multiple DC standards into a single hardware platform . Therefore, it significantly reduces the need for external signal converters and simplifies spare parts management across the plant.

Technical Specifications

Input Versatility and Adaptive Logic

The ADV144-S13 module employs adaptive threshold detection logic, automatically recognizing DC presence across the entire 24–250 V range without requiring hardware jumpers or software configuration . Consequently, this single module can directly interface with 24 V instrument loops, 110 V battery-backed switchgear statuses, and 220 V DC motor control signals within the same I/O rack. Each channel provides optical isolation from the system bus, protecting the controller from voltage transients and ground loops .

System Integration and Redundancy

This module mounts directly into Yokogawa FIO nests and supports dual-redundant configurations for critical safety and control loops . The pressure clamp terminal connection ensures secure field wiring, while the -S13 suffix indicates the isolated variant with screw-type terminals. Furthermore, the module supports both status input for standard ON/OFF detection and pushbutton input for edge-counting applications .

Application Scenarios

This versatile input module is widely deployed in power substations for monitoring DC battery-backed switchgear status, in large-scale refining where diverse voltage standards coexist, and in safety feedback loops requiring redundant high-voltage interlock monitoring . It also serves Remote Terminal Units (RTUs) for interfacing legacy field equipment with non-standard DC voltages . For AC signals, users should select the ADV141 (100–120 V AC) or ADV142 (200–240 V AC) modules instead .
