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 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.
