Available
*1: This module Yokogawa Analog Input Module AAI143-S53 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-S53 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-S53 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.MODELS AND SUFFIX CODES
