Product Overview:
The Yokogawa NFAI841-S00 (also available as A4S00) is an advanced Analog Input Module designed for CENTUM CS 3000 systems. It efficiently acquires analog signals from sensors such as pressure transmitters, temperature elements, and flow devices, converting them into reliable digital data for processing.
With 8 independent analog input channels, this module supports both current and voltage inputs. It ensures flexibility for diverse instrumentation, while its non-isolated design with pressure clamp terminals allows secure and simplified wiring.
Engineered with industrial-grade build quality, EMI shielding, and vibration resistance, the NFAI841-S00 guarantees long-term stability in harsh industrial environments. It also integrates fallback features, providing HOLD or SETV options per channel to maintain safe operation during communication loss.
