Product Description
The NFDV151-P10 S (NFDV151) is a high-density digital input module designed for Yokogawa STARDOM autonomous controllers, including the FCN-500, FCN-RTU, FCN-100, and FCJ series. This module provides 32 isolated input channels compatible with both sink and source devices at 24 V DC.
Engineered for precision and durability, the NFDV151 features pushbutton edge detection and integrated surge protection, making it ideal for monitoring status contacts, limit switches, and operator pushbuttons in complex industrial environments. Its 2 kV AC isolation protects the controller backplane from field-side electrical surges, ensuring reliable operation in harsh conditions.

Frequently Asked Questions
What is the benefit of the "Pushbutton" mode on this module?
The pushbutton mode uses edge detection circuitry to reliably capture brief pulses (minimum 20 ms) that might be missed by standard scan cycles, ensuring operator commands or fast sensor triggers are recorded accurately.
How are the 32 channels grouped for wiring?
The 32 channels are divided into two groups of 16. Each group is isolated from the system and from each other by 500 V AC, allowing separate 24 V DC sources to be used for different field sections if required.
