Product Description
The NFDR541 (NFDR541) is a 16-channel relay output module designed for the Yokogawa STARDOM autonomous controller platform. It provides reliable dry-contact switching for high-capacity field devices such as solenoids, motor starters, and alarm indicators.
By employing mechanical relay isolation, the NFDR541 offers strong immunity to electrical noise and supports a wide range of AC and DC load voltages. Its high-current switching capability makes it suitable for controlling final elements in complex industrial automation systems.

Frequently Asked Questions
What types of loads are best suited for the NFDR541 module?
The NFDR541 is ideal for inductive loads like relay coils or small actuators. Its mechanical contacts provide complete electrical isolation between the STARDOM backplane and high-voltage field wiring.
Can I use this module for high-speed pulse outputs?
No, due to the mechanical relay contacts, the NFDR541 is intended for standard on/off control. For high-speed or frequent switching applications, solid-state output modules should be used to prevent contact wear.
