Product Description

The Yokogawa ADV551-P50/D5A00 S1 is a 32-channel high-density digital output module for the CENTUM VP Integrated Production Control System. It functions as a current-sink (transistor contact) interface for discrete field devices such as relays, signaling lamps, and small solenoid valves.

The P50 functional set provides Pulse Width Output and Time-Proportional Output, enabling precise duty-cycle control for heating loops, dosing pumps, and similar processes. The ATD5A-00 adapter simplifies installation by allowing a single KS cable connection. The S1 style code represents the original hardware revision, maintaining full compatibility with standard FIO communication nests.

Technical Specifications

Functional Code Breakdown

• Suffix P – Enables Pulse Width and Time-Proportional output for duty-cycle-based process control.

• Suffix 5 – Standard industrial version; no LED status display, non-explosion proof.

• Suffix 0 – Basic hardware for standard industrial environments.

• Option /D5A00 – Pre-installed ATD5A-00 KS cable interface adapter for simplified cabinet wiring.

Industrial Applications

• Duty-Cycle Heating – Drives solid-state relays for furnace or oven temperature control.

• Precision Dosing – Controls solenoid pumps using pulse-width modulation for chemical injection.

• Cabinet Optimization – High-density 32-channel format reduces space requirements in control room marshalling cabinets.

Technical FAQ

Q: Difference between S1 and S2 style codes?
A: S1 is the original hardware revision. Functionally identical to S2, it is preferred for like-for-like replacements in older systems.

Q: How does the current-sink output work?
A: The module connects the load to the ground (negative). The external device must connect between the +24 V DC supply and the module output.

Q: Does the module display channel status?
A: No, the P50 version lacks an LED status display. Monitoring is performed via the DCS HMI.
