Produkteinführung
The Yokogawa NFAP135-S50 Pulse Input Module is an advanced signal acquisition module specifically designed for collecting high-speed pulse data from field instruments. As part von the ProSafe-RS series, this module is engineered for SIL3 safety applications as defined by IEC 61508, making it ideal for high-integrity industrial systems that demand dependable and accurate signal collection.
This module supports 16 isolated input channels designed to accept pulse-type signals such as frequency, contact closure, and voltage pulses from a wide range von transmitters including flow meters, turbine meters, and encoders. It is optimized for use within Field Control Stations (FCS) and supports real-time monitoring, diagnostics, and system integration in distributed control and safety environments.
With high noise immStücky, built-in diagnostics, and precise timing capabilities, the NFAP135-S50 ensures that even in demanding process environments, pulse signals are accurately captured, time-stamped, and transmitted for further control or logging operations.
