Description
Product Overview
Part Number: ADV551-P00 Manufacturer: Yokogawa (Yokogawa Electric, Japan) Product Series: CENTUM VP DCS, FIO Field I/O Module Type: Digital Output Module (DO) ADV551-P00 is a 32-channel group-isolated transistor sink digital output module for Yokogawa CENTUM VP FIO nodes. It converts digital on/off commands from FCS controller into 24VDC field switching signals to drive solenoid valves, motor contactors, indicator lamps and alarm devices. The P suffix version supports pulse width modulation (PWM) and time-proportional output for special timing control applications. It communicates with the controller over ESB bus, widely used in petrochemical, power, oil & gas and chemical plants for discrete sequence control and interlock logic. Supports hot swap and dual-redundant installation.

Engineer Notes
- ADV551-P00 belongs to FIO series I/O module for CENTUM VP, not compatible with old CS3000 system.
- P suffix = pulse / time-proportional output enabled. Standard ADV551 without P only supports simple ON/OFF status output.
- Output is sink type (NPN), field device positive side connects to 24VDC positive, module provides ground return path.
- Supports dual redundant pair configuration. Automatic switchover upon module fault without interrupting discrete control outputs.
- Hot-swap function allows module removal and replacement while DCS online, no system shutdown required.
- Match with Yokogawa terminal boards or AKB331 dedicated cable for field wiring; add flyback diode for inductive loads (solenoid coils) to suppress surge voltage.
- Built-in circuit diagnostics, detect short-circuit fault on output channel. Check front LED indicators for power, ESB communication and channel fault status during commissioning and maintenance.
Pre-Shipment Test Protocol

Buyer FAQ
Q: Is ADV551-P00 new original? A: We supply brand new original Yokogawa units, 12-month warranty, factory test certificate available on request.
Q: What does suffix P00 mean? A: P = supports pulse width / time proportional output; 00 = standard non-explosion-proof basic version for FIO node.
Q: What is the difference between ADV551-P00 and ADV551-S00? A: ADV551-P00: supports pulse & time proportional output; ADV551-S00 only simple digital ON/OFF output without pulse function.
Q: Can ADV551-P00 work in redundant configuration? A: Yes, two ADV551-P00 modules can be configured as dual redundant pair with corresponding redundant terminal block.
