Technical Overview

The ADV551-P03 S2 is a high-density discrete output module for the Yokogawa CENTUM VP and CS 3000 systems, providing 32 transistor-based output channels. The -P03 suffix enables pulse width and time-proportional output functions, while the S2 hardware revision ensures enhanced thermal stability and long-term reliability.

This module is designed for fast, low-power DC switching, making it ideal for controlling solenoids, pilot valves, annunciators, and SSR-driven heaters.

Technical Specifications

Functional Applications

• Solenoid Valve Control: Driving small pilot valves in hydraulic or pneumatic manifolds.

• Annunciator Panels: Operating LEDs, alarms, and indicator sirens in control rooms.

• Time-Proportional Heating: Controlling SSRs for temperature regulation through duty cycle modulation.

• Inter-System Signaling: Providing status and handshaking signals to PLCs or Safety Instrumented Systems (SIS).

Technical FAQ

What is the advantage of the Style 2 (S2) revision?

• S2 represents a hardware update with better heat dissipation and power efficiency.

• Fully backward compatible with standard ADV551 slots while offering improved long-term reliability.

Can this module drive 110V AC loads?

• No. The ADV551-P03 S2 is DC-only (≤ 30 V DC).

• Use an interposing relay for AC or higher-current DC applications.

How does the pulse width function work in the -P03 model?

• The module varies the ON vs OFF time within a cycle.

• Useful for dosing pumps or heating elements, allowing average power regulation through duty cycle control.
