Product Overview
The Yokogawa NFDR541-P00 Relay Output Module is a high-performance I/O component designed for the STARDOM autonomous controller system (FCN/FCJ series). This module delivers 16-channel isolated relay contact output, suitable for both DC and AC voltage applications. It is engineered to ensure operational integrity in control environments requiring reliable status outputs, with robust safety features including fallback operation modes and channel isolation.
The NFDR541 series includes variants that either meet or do not meet RoHS compliance; the “P00” version is a non-RoHS standard relay output type. The design emphasizes industrial-grade durability, easy field wiring via pressure clamp terminals, and safety with high-voltage isolation.

Frequently Asked Questions (FAQ)
Q1: What voltage ranges can the NFDR541-P00 module handle?
A1: It supports 24 to 125 V DC and 100 to 240 V AC at 50/60 Hz.
Q2: How many output channels does the module provide?
A2: The NFDR541-P00 offers 16 independent relay output channels.
Q3: Is the module RoHS compliant?
A3: The NFDR541-P00 variant is not RoHS compliant. Use the “NFDR541-Txx” variants for RoHS compliance.
Q4: What are the fallback modes supported?
A4: It supports HOLD (retain last state), OFF (reset to OFF), and NO (no action) modes.
Q5: Can this module handle inductive loads like solenoids?
A5: Yes, but the load current is derated (e.g., 0.6 A @ 24 V DC), and external diodes are recommended for DC inductive loads.
Q6: What is the maximum response time of this relay module?
A6: It is 12 milliseconds or less.
Q7: What kind of external connections does the module support?
A7: It uses pressure clamp terminals for reliable and quick wiring.
Q8: Can it be used with mixed AC and DC loads?
A8: Yes, but the AC signals sharing the same common must be in the same phase to avoid potential damage.
Q9: Is there any limitation per common channel?
A9: Yes, the maximum total current per common is 8 A.
Q10: What are the module’s dimensions and weight?
A10: The dimensions are 130 x 111.5 x 32.8 mm, and it weighs 0.3 kg.
