Product Description

The ASD533-S00/SD3S0 is a high-capacity digital output module developed by Yokogawa Electric Corporation for the FIO (Field network I/O) subsystem, used in CENTUM VP and ProSafe-RS control systems.

This module is engineered to drive high-current field devices such as solenoid valves, relays, and motor actuators, providing fast and precise output control while protecting the system backplane from electrical surges.

The SD3S0 variant includes a built-in intrinsic safety barrier, making it suitable for hazardous environments. It supports sinking and sourcing configurations, offering flexible integration with diverse field wiring standards.

Technical Specifications

Application and Connectivity

The ASD533-S00/SD3S0 is ideal for high-speed discrete control loops where high-current output is required. Typical applications include:

• Burner Management Systems (BMS)

• Emergency Shutdown (ESD) interfaces

• Heavy-duty solenoid actuation in chemical, oil, and gas plants

It ensures reliable actuation of field devices while maintaining system integrity and safety compliance.

Technical FAQ

Can it drive inductive loads directly?
Yes, but external flyback diodes or surge suppressors are recommended when switching highly inductive devices to prevent back-EMF damage.

What does the /SD3S0 suffix signify?
The -S00/SD3S0 suffix identifies the hardware revision, environmental coating, and style code, ensuring compatibility with FIO baseplates and firmware.

Does the module support redundancy?
Yes. Two ASD533 modules installed in a redundant FIO node unit can provide a dual-redundant output configuration, maintaining control of field devices even if one module fails.
