Product Model: Yokogawa ADV551‑DO32
Brand: Yokogawa
Series: ADV551 Series – Digital Output Modules
Product Introduction
The ADV551‑DO32 is a 32‑channel digital output module designed for industrial automation and control systems. It belongs to Yokogawa’s I/O platform and is built for applications where many discrete output signals (relays, solenoids, actuators, indicators) must be controlled in a reliable, compact and fast manner.
This module supports 24 V DC output signals, providing current‑sink transistor outputs with robust isolation and industrial‑grade electrical performance. It integrates into control racks or I/O stations, enabling system integrators to manage many outputs in a single module. The ADV551 series modules are widely used in process automation, manufacturing systems and utilities, and the “DO32” designation reflects the 32 output points provided.
With its compact size, high channel density and platform compatibility, the ADV551‑DO32 is an excellent choice for system expansion or new installation where space, wiring complexity and performance all matter.

Applications
-
Process control systems in chemical, petrochemical, power generation or refinery plants, where many discrete output devices (valves, solenoids, actuators, alarms) need to be driven reliably.
-
Manufacturing automation systems (assembly lines, machine control) where multiple digital output points must be managed from a central controller, reducing the number of modules and rack slots.
-
Water treatment, utilities and infrastructure control (pump drives, motor control, alarm lamps, field devices) benefiting from high channel density output modules.
-
I/O rack expansion or retrofit projects: the ADV551‑DO32 allows adding up to 32 outputs per module, thus reducing wiring and footprint compared to many smaller modules.
-
Systems requiring fast digital outputs or time‑based output functions (pulse width or time‑proportioning) in demanding environments with high electrical noise, vibration or temperature variations.
Advantages
-
High channel density: 32 output channels in a single module enable fewer modules, less wiring and reduced panel/rack footprint.
-
Robust electrical performance: Withstanding voltage, low leakage, current‑sink outputs and industry‑grade isolation deliver reliable field device control even in electrically harsh environments.
-
Fast response: Status output response time of ≤ 3 ms ensures real‑time performance for many automation tasks.
-
Flexible output capability: Modules in this series often support both standard ON/OFF status outputs and advanced functions such as pulse width or time‑proportional outputs.
-
Compact & lightweight: Approx. 107.5 × 130 × 32.8 mm size and ~0.20 kg weight make installation easier, especially in dense I/O racks or limited cabinet space.
-
Platform compatibility: Designed to integrate into Yokogawa’s I/O family, sharing base frames, cable systems and maintenance practices, easing system integration and spare‑parts management.
-
Reduced installation cost: Fewer modules and simplified field wiring lead to lower installation time, less cabinet space and reduced overall system cost.
-
Reliable long‑term performance: Built to operate in industrial conditions with wide temperature and humidity tolerance, offering dependable control over time.
