Product Description
Product Overview
The Yokogawa NFAP135-S01 is a Pulse Input Module designed to receive contact ON/OFF, voltage pulse, and current pulse signals across 8 isolated channels. It is isolated between the input signals and the system, as well as between channels, making it a robust solution for industrial pulse measurement applications.
