Product Model: Yokogawa ADV551‑P00
Brand: Yokogawa
Series: ADV551 Series – Digital Output Modules
Product Introduction
The ADV551‑P00 is a 32‑channel digital output module designed for industrial automation and control‑system use. It provides a high‑density discrete output solution, capable of driving field devices such as solenoids, relays, indicators, actuators and other 24 V DC loads from a control system interface.
As part of the ADV551 series, this module is engineered for reliability, fast response and compact installation in I/O racks. Its designation “P00” indicates that it is the basic version of the module (i.e., without extended options such as status display, explosion protection, or special temperature ratings).
The module supports a 24 V DC nominal output voltage, with each of the 32 output channels offering current‑sink format, allowing for direct connection of compatible field devices. The compact build and platform compatibility make it suitable for system expansion, retrofit projects or new installations in process, manufacturing, utility or infrastructure applications.

Applications
-
Process control systems (e.g., chemical plants, petrochemical facilities, power generation) where multiple discrete output devices must be driven reliably.
-
Manufacturing automation systems (assembly lines, machine control) where many output points are required, and a high‑density module reduces rack footprint and wiring.
-
Utilities and infrastructure (water/wastewater treatment, pump stations, motor control) where many relay/solenoid outputs are used.
-
I/O rack expansion or retrofit scenarios where existing systems need additional output capacity without expanding cabinet size significantly.
-
Automation systems requiring both standard ON/OFF control of outputs and, in variant modules, time‑proportioned or pulse width outputs for more advanced control logic.
Advantages
-
High channel density: 32 discrete outputs in one compact module means fewer modules, less wiring and a smaller cabinet footprint.
-
Robust electrical design: Strong isolation (2 kV AC between signal and system, 500 V between commons), low leakage current, and current‑sink outputs deliver reliable performance in industrial environments.
-
Fast response time: Status output response of ≤ 3 ms ensures timely control of field devices and supports real‑time system demands.
-
Compact and lightweight: At around 0.20 kg and modest dimensions, the module is easy to install and manage even in tight rack space.
-
Platform compatibility: As part of the ADV551 series, it integrates into established Yokogawa I/O systems — simplifying integration, spare‑parts management and system expansion.
-
Installation efficiency: High density + standard connections reduce wiring, terminal blocks and installation time — lowering cost and complexity.
-
Flexible control capability: While the “P00” base version supports ON/OFF outputs, the series offers variants that add pulse width or time‑proportioning features, enabling more advanced control when needed.
-
Durable long‑term performance: Designed for industrial ambient conditions, the module is built to perform reliably over time in maintenance‑friendly configurations.

FAQ – Frequently Asked Questions (10 Q&A)
Q1: How many output channels does the ADV551‑P00 provide?
A1: It provides 32 discrete digital output channels in one module.
Q2: What voltage does this module operate on?
A2: The module uses a nominal 24 V DC applied voltage, typically in a range of 20.4 to 26.4 V DC.
Q3: What is the maximum load current per channel?
A3: Each channel can handle up to approximately 100 mA when operating near the upper supply voltage (~26.4 V).
Q4: How fast does the module respond when an output is activated?
A4: For status ON/OFF outputs the response time is ≤ 3 ms; when using mixed status and pulse‑width outputs the response may be ≤ 10 ms.
