ADV551-P63/D5A00

The Yokogawa ADV551-P63/D5A00 is a 32-channel, 24 V DC isolated Digital Output Module designed to provide discrete control signals to external devices. It supports current-sink output operation and pulse width/time-proportional output functions. This configuration includes status indication, ISA Standard G3 and extended temperature options, together with a KS Cable Interface Adapter (ATD5A-00).

Functional Description

The ADV551-P63/D5A00 converts digital control commands from the control system into electrical output signals for connected field circuits. Its 32 output channels support individual discrete control, while the current-sink configuration allows the module to switch connected loads by providing a path to the common negative side.

The -P suffix adds pulse width output and time-proportional output functions. These functions allow the control system to represent a time-based control demand through the ON/OFF duration of an output signal, rather than relying only on steady-state discrete switching.

Output Configuration

The module operates with a rated applied voltage of 24 V DC and supports a maximum load current of 100 mA per channel at 26.4 V. The actual load must remain within the specified channel current limit and voltage conditions.

The common negative (-) side is arranged in groups of 16 channels. This grouping is relevant when planning field wiring and connecting external loads, particularly where channel commons and isolation boundaries must be considered.

Model Configuration and Ordering Information

The complete ordering number identifies the following configuration:

Code	Description
ADV551	32-channel, 24 V DC Digital Output Module
-P	Pulse width output and time-proportional output functions
6	With status display; without explosion protection
3	ISA Standard G3 option and -20 to 70 deg C temperature option
/D5A00	KS Cable Interface Adapter for 32-channel digital signals, model ATD5A-00

The /D5A00 option identifies the cable interface arrangement supplied for this configuration. It should be distinguished from pressure-clamp terminal block options such as ATD5S-00, which have different connection arrangements.

Pulse Width and Time-Proportional Output

The ADV551 supports three output assignment patterns: status output, pulse width or time-proportional output, and mixed status/pulse/time-proportional output. These functions allow the module to handle conventional ON/OFF commands as well as time-based output signals.

For pulse width output, two consecutive channel terminals are required, with the first terminal being an odd-numbered channel. When pulse width and time-proportional outputs are combined, the terminal assignment must follow the manufacturer's channel configuration rules.

Electrical Isolation and Field Wiring

The module provides electrical withstand capability between output signals and the system, as well as between channel commons. Its 16-channel common grouping means that the 32 outputs are arranged into two common groups.

When connecting DC relay loads, Yokogawa specifies the use of a spark killer diode. The external load and wiring must also remain within the rated voltage and current limits.

Frequently Asked Questions

Q: Does the ADV551-P63/D5A00 support pulse width output?

A: Yes. The -P suffix identifies the pulse width and time-proportional output functions. Pulse width output requires two consecutive terminals, starting with an odd-numbered terminal.

Q: What cable interface is specified for the ADV551-P63/D5A00?

A: This configuration specifies the KS Cable Interface Adapter ATD5A-00 through option code /D5A00. The adapter is intended for the 32-channel digital connection arrangement.

Q: Is the ADV551-P63/D5A00 suitable for operation without explosion protection?

A: Yes. Suffix code 6 specifies the version with status display and without explosion protection. It should not be confused with the explosion-protected suffix configurations.
