Product Description
The Yokogawa ADV557-S00 is a high-density 32-channel digital output module designed for the CENTUM VP Integrated Production Control System. As part of the FIO (Field network I/O) family, this module provides current-sink transistor outputs to drive discrete field devices such as solenoid valves, auxiliary relays, and pilot indicators.
The ADV557-S00 supports standard ON/OFF switching as well as advanced pulse-width modulation (PWM) and time-proportional control, enabling precise digital control for thermal processes and other duty-cycle-dependent applications. Robust 2 kV AC isolation ensures protection of system logic from field-side transients. Its compact design, along with pressure-clamp terminal compatibility, allows high-density installation in space-constrained control cabinets.

Functional Capabilities
-
Current-Sink Output: Switches the negative side of the load; external 24 V DC must be applied to the positive side.
-
Advanced Pulse Logic: Supports one-shot pulse outputs and time-proportional control for digital outputs acting like analog signals.
-
Grouped Isolation: Channels are isolated in two groups of 16 to prevent cross-channel electrical faults.
-
Redundancy Support: Compatible with dual-redundant node units for uninterrupted operation of critical control loops.
Industrial Applications
-
Process Automation: Drives solenoid valves, relays, and pilot lamps in chemical, power, and refining plants.
-
Thermal Process Control: Provides time-proportional output for heaters or dosing pumps.
-
High-Density I/O Systems: Consolidates 32 outputs in a single module to optimize cabinet space.
Technical FAQ
Q: How does the ADV557 differ from the ADV551?
A: The ADV557 is optimized for certain node units (UM or generic FIO), with firmware tailored for pulse logic or SOE handling. Verify compatibility before installation.
Q: Can it drive large inductive loads like DC motors?
A: No, the module is rated 100 mA per channel. Use an interposing relay for larger motors to protect the outputs.
Q: Is external surge protection required?
A: Yes, external flyback diodes are recommended when driving inductive loads to prevent back-EMF damage.
