6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Overview
The ADV551-P50/D5S00 is a high-density digital output module manufactured by Yokogawa Electric Corporation for use in CENTUM distributed control systems and ProSafe-RS safety platforms. It provides reliable ON/OFF signal control for a wide range of field-level devices, supporting stable operation in continuous industrial processes.
Designed as part of Yokogawa’s advanced Field I/O (FIO) architecture, this module combines compact mechanical design with robust electrical performance, making it suitable for both standard process control and safety-related applications.
Core Functions
The ADV551-P50/D5S00 delivers discrete digital output signals to actuators and switching devices. Each output channel operates independently, allowing precise control of multiple field instruments from a single module.
The module is typically used to drive solenoid valves, interposing relays, alarms, and other binary-controlled equipment requiring dependable 24 V DC switching.

Comparison with Similar Models
Compared with lower-channel ADV series modules, the ADV551-P50/D5S00 offers significantly higher output density, reducing cabinet space and simplifying wiring. Unlike digital input modules such as ADV151 series units, this model is specifically designed for output signal driving rather than field status acquisition.
FAQ
Q: Is the ADV551-P50/D5S00 a digital input or output module?
A: It is a digital output module. It provides ON/OFF control signals to field devices and does not accept input signals.
Q: Can this module be used in safety systems?
A: Yes. It is compatible with Yokogawa ProSafe-RS when configured according to system safety requirements.
Q: What type of terminal block is included?
A: The /D5S00 option includes a pressure clamp terminal block (ATD5S-00), suitable for secure field wiring.
