YOKOGAWA NFDR541-P00 S2 – 16-Channel Relay Output Module | STARDOM FCN/FCJ Platform
The YOKOGAWA NFDR541-P00 S2 is a high-density digital output module engineered for the STARDOM FCN/FCJ autonomous controller platform. Designed to drive relay-based field devices — including solenoid valves, motor starters, alarm annunciators, and discrete actuators — this module delivers deterministic switching performance in demanding industrial environments. Procurement engineers sourcing replacement or expansion DO cards for STARDOM-based control systems will find the NFDR541-P00 S2 a direct, specification-matched solution available through Konmask.com with full traceability.
Product Positioning: The NFDR541-P00 S2 occupies the relay digital output slot within the STARDOM FCN I/O subsystem. Its 16-channel architecture maximizes cabinet density while maintaining galvanic isolation per channel — a critical requirement for mixed-voltage field wiring in oil & gas, chemical, and power generation applications.

- STARDOM Native: Plug-and-play recognition by FCN controller; no additional configuration hardware required
System Architecture & Signal Flow
The NFDR541-P00 S2 installs into any available I/O slot of the STARDOM FCN chassis. The FCN controller writes digital output values to the module via the proprietary I/O bus each scan cycle. Internally, each channel drives a dedicated relay coil; the dry contact output is wired to the field terminal block. Field wiring connects to the module’s screw-terminal or connector assembly (verify terminal type with site drawings). The relay contact state is reflected back to the controller for diagnostic confirmation. No external relay panel is required for standard 250 V AC / 2 A loads.

Technical FAQ
Q: Is the NFDR541-P00 S2 compatible with both FCN and FCJ controllers?
A: Yes. The module is designed for the STARDOM FCN/FCJ I/O bus and is recognized by both controller variants.
Q: Can I mix NFDR541-P00 S2 with other STARDOM I/O modules in the same chassis?
A: Yes. STARDOM FCN supports mixed I/O module types within the same chassis, subject to slot and power budget constraints.
Q: What is the difference between NFDR541-P00 and other NFDR5xx variants?
A: The NFDR541-P00 is the relay contact DO variant. Other NFDR5xx modules may offer transistor (solid-state) outputs or different channel counts — verify part numbers against your FCN I/O configuration tool.
Q: Do you supply the terminal block / connector assembly separately?
A: Yes. Contact Konmask.com with your terminal assembly part number for availability and pricing.
Q: What certifications does this module carry?
A: CE and RoHS. For SIL-rated applications, consult the YOKOGAWA STARDOM safety manual and your functional safety engineer.
