Product Model: Yokogawa ADV551-P50 S2
Brand: Yokogawa
Series: ADV551 Series – Digital Output Modules
Product Introduction
The ADV551-P50 S2 is a high-performance 32-channel digital output module built for industrial automation and process control systems. Within the ADV551 family, the “P50” suffix indicates that this variant supports pulse-width and time-proportional output functions (in addition to standard ON/OFF outputs), while the “S2” denotes a specific revision or option set. This module is designed to drive 24 V DC discrete field devices—such as solenoids, relays, indicator lamps and actuators—via current-sink outputs, all in a compact rack-mountable format.
Because space, wiring complexity and system reliability matter in modern automation, the ADV551-P50 S2 combines 32 channels in one module, supports enhanced output functions, and integrates smoothly into Yokogawa’s modular I/O architecture. The module features high electrical isolation, fast switching, and efficient installation wiring flexibility—making it a strong fit for plants, manufacturing lines, utilities and retrofit scenarios requiring dense output control.

Applications
-
In large-scale process plants (chemical, petrochemical, power generation) where dozens of discrete outputs such as solenoid valves, alarms, relays and actuators must be managed reliably.
-
In manufacturing automation systems (assembly lines, machine control, robotics) where high-density output control is needed and wiring/cabinet space are constrained.
-
In utilities/infrastructure (water/wastewater treatment, pumping, motor control centres) where discrete output devices are numerous and need efficient I/O modules.
-
In retrofit or expansion scenarios: When an existing I/O rack must be expanded to support more output channels without increasing cabinet size, the ADV551-P50 S2 offers 32 channels in one slot, reducing module count and wiring.
-
In systems requiring timed control: The module’s pulse-width and time-proportional output capability allow more advanced control of actuators, making it suitable for modern automation environments beyond simple ON/OFF switching.
Advantages
-
High output density: 32 channels per module reduce the number of modules, wiring paths and rack slots required.
-
Compact & lightweight: At approx. 0.20 kg and modest dimensions, the module fits well into dense rack environments.
-
Enhanced control functions: Pulse-width/time-proportional output capability provides flexibility beyond standard digital output.
-
Robust electrical isolation: Withstanding voltages up to 2 kV AC protect the system in noisy industrial environments.
-
Fast switching: Response times ≤ 3 ms ensure timely signal delivery to field devices.
-
Modular integration: Compatible with Yokogawa I/O platform—standard form-factor and interface simplify system design and maintenance.
-
Cost efficiency: Fewer physical modules, fewer wiring terminations, simpler installation and maintenance reduce total cost of ownership.
-
Future-proof scalability: The advanced output functions and modular architecture support evolving automation requirements without redesigning the infrastructure.
