YOKOGAWA ADV551-P00 | DIGITAL INPUT MODULE

The YOKOGAWA ADV551-P00 is a Yokogawa digital input module designed for CENTUM VP distributed control systems. It is used to receive ON/OFF status signals from field devices such as switches, contacts, relays, and other discrete sensors, and transfer those states to the control system.

The ADV551 belongs to Yokogawa’s ADV550 series digital input modules. The P00 suffix identifies a specific hardware/configuration version, so the complete suffix should be matched when replacing an installed module.

📖 Product Usage Instructions

The ADV551-P00 receives discrete field signals and converts the electrical ON/OFF condition into digital status information for the CENTUM VP control system.

For example, a motor auxiliary contact can be connected to an input channel. When the motor starts, the contact changes state and the ADV551 detects the change. The CENTUM control system can then use that status for monitoring, sequencing, alarming, or interlock logic.

The same principle can be applied to valve position switches, pump feedback contacts, circuit-breaker auxiliary contacts, level switches, and equipment alarms.

When commissioning a replacement module, do not rely only on the module LED. The actual field signal should be checked from the terminal side and then verified on the DCS display.
