Product Overview
The Yokogawa NFDV161-P51 is a high-density digital input module. It belongs to the reliable Yokogawa Centum VP control system series. This module processes 64 isolated digital input signals. It operates on a 24V DC power supply. The design uses two 50-pin MIL connectors for secure field wiring.
It supports standard status inputs and push-button edge counting. The hardware isolates channels in groups of 16 to prevent electrical noise propagation. This module ensures stable signal collection in demanding industrial sites.

Frequently Asked Questions (FAQ)
- Can I use both sink and source wiring on this module?
Yes, the common lines group per 16 channels and support plus or minus configurations. - What is the primary function of the push-button edge count mode?
It captures fast momentary signals without missing transitions during PLC scan times. - Does the module require external 24VDC loops to function?
Yes, the field-side loops require an external 24VDC source to drive the input photo-couplers.
