Yokogawa NFAI543-H50 Analog Output Module
Overview
NFAI543-H50 (version S1) is an analog output module from Yokogawa with 16 output channels, each channel is isolated from each other, the output signal is 4 - 20 mA, and the module has HART communication function and fault fallback protection, and the load resistance range is 0 - 750 Ω, which can be used for precise adjustment of process control valves/actuators.
Function&Features：
Yokogawa NFAI543-H50
Isolation withstand voltage:
The withstand voltage between the channel and the system is up to 1500 V AC (500 V AC when using MIL cable).
Fault protection:
NFAI543-H50 supports two fallback modes: HOLD (hold current value) or SETV (output set value).
HART support:
NFAI543-H50 can communicate with smart instruments via HART protocol (external 24 V DC power supply required).
