*1: This module Yokogawa Analog Input Module AAI143-HE3 does not allow a Zener barrier to be connected. If the module is to be used in intrinsically safe applications, use an isolation barrier.

*2: Viewed from the terminals, module input resistance is, depending on the current flowing:

250 Ω +（ voltage drop (0.4 V maximum) in the input protection circuit）/（current value）

*3: When installing the module Yokogawa Analog Input Module AAI143-HE3 with HART function to a remote node, the firmware of EB401 must be Rev 2 or later.For HART function specifications, refer to “HART Communication Package (for A□I□□□-H) (GS 33Q03L70-31E).”

*4: The withstanding voltage for using the dedicated cable is 500 V AC (between the input signal and the system).The withstanding voltage for using MIL connector cable depends on the electrical specifications of its cable.

*5: This voltage is developed between connecting terminals for this Yokogawa Analog Input Module AAI143-HE3 module’s 2-wire transmitter. When calculating if transmitter minimum operating voltage requirement will be satisfied, remember to allow for voltage drop in external wiring.
