ADV551-P50/D5D00

The Yokogawa ADV551-P50/D5D00 is a 32-channel, 24 V DC isolated digital output module for the CENTUM VP FIO system. It provides discrete transistor output signals for controlling external field devices. This configuration includes the pulse width output function and a dual pressure clamp terminal block (ATD5D-00), providing a defined interface for field wiring.

Functional Description

The ADV551 converts digital output commands from the control system into discrete electrical signals for external loads. Its 32 isolated output channels support individual control signals, allowing the controller to operate connected devices according to the configured control logic.

The module supports pulse width output and time-proportional output functions. These functions allow digital switching signals to represent a variable control demand through changes in pulse duration or duty cycle, where supported by the application configuration.

Terminal Block Configuration

The /D5D00 option identifies the dual pressure clamp terminal block configuration, associated with Yokogawa model ATD5D-00. This is the specified field wiring interface for the supplied module configuration.

The terminal block option should be checked against the installed cable and field wiring arrangement when replacing an existing module. The /D5D00 version should not be confused with /D5S00, which specifies a standard pressure clamp terminal block.

Output Characteristics and Signal Configuration

The ADV551 uses current-sink transistor outputs. The field-side external supply provides the operating voltage for connected loads, while the module controls their switching states. The specified maximum load current is 100 mA per channel at 26.4 V DC.

The module supports three output functions:

• Status Output (SO): Provides conventional ON/OFF switching signals.
• Pulse Width Output (PW): Generates one-shot pulses with a configurable pulse width.
• Time-Proportioning Output (TP): Controls ON/OFF duration according to a time-proportioning demand.

For pulse width output, two consecutive terminals are assigned to one pulse output, with the first terminal required to have an odd number. This terminal allocation must be considered when configuring the module and planning field wiring.

Suffix and Ordering Code Identification

Code	Description
ADV551	32-channel, 24 V DC isolated digital output module
-P	Pulse width output and time-proportional output functions
5	Without status display; without explosion protection
0	Basic type
/D5D00	Dual pressure clamp terminal block, model ATD5D-00

The complete ordering number identifies the module together with its functional and terminal configuration. In particular, the /D5D00 option distinguishes this version from standard pressure clamp terminal block configurations.

Frequently Asked Questions

Q: What is the difference between ADV551-P50/D5D00 and ADV551-P50/D5S00?

A: Both use the ADV551 digital output module, but their terminal block configurations differ. The /D5D00 version specifies a dual pressure clamp terminal block (ATD5D-00), whereas /D5S00 specifies a pressure clamp terminal block (ATD5S-00).

Q: Can the ADV551-P50/D5D00 generate pulse width output signals?

A: Yes. The -P suffix identifies pulse width and time-proportional output functionality. Pulse width output supports a range of 8 ms to 7200 s, with an 8 ms resolution.

Q: What should be checked when replacing this module?

A: Verify the 32-channel configuration, 24 V DC field supply, current-sink output requirements, load current, and ATD5D-00 terminal block arrangement. Also check the configured output modes and terminal assignments, particularly where pulse width outputs are used.
