STANDARD SPECIFICATIONS

Current/Voltage Input Modules (Non-Isolated)

Yokogawa DCS CENTUM VP Analog Input Module AAI141

These modules mainly receive 4 to 20 mA DC or 1 to 5 V DC standardized signal from 2-wire/4-wire transmitters.

They can be used in dual redundant configuration.

*1: This Yokogawa Analog Input Module AAI141 does not allow a Zener barrier to be connected. If the module Yokogawa Analog Input Module AAI141 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 (3 V maximum) in the input protection circuit)/(current value)

*3: This voltage is developed between connecting terminals for this 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.

*4: R3.02 or later version supports HART function. When installing the module 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).”
