Product Overview
The Yokogawa NFAI543-S50 is a 16-channel analog output module designed for ProSafe-RS safety instrumented systems (SIS). It provides isolated current outputs (4–20 mA) to field devices such as control valves, actuators, and transmitters, ensuring reliable operation in high-integrity industrial applications.
This module supports HART communication, enabling advanced diagnostics, remote configuration, and monitoring. Each channel features fallback options, either HOLD to maintain the last value or SETV to move to a predefined value in case of faults. The unit requires a 24 V DC field power supply and ensures robust isolation between system and field wiring.
