Product Description
Product Overview
The Yokogawa NFAF135-S50 S1 is a Frequency Input Module designed to compute frequency by analyzing the number of rising edges and pulse intervals from external pulse inputs. It processes these signals and transmits the resulting process values to the CPU module via the communication bus in the base module, making it a key component for frequency-based monitoring in industrial systems.
