Frequently asked questions
Specific answers for replacement, compatibility, wiring and commissioning decisions for AEA4D.
What is the YOKOGAWA AEA4D used for?
AEA4D is a 16-channel analog terminal board that provides M4 screw field terminals for supported single or dual-redundant Yokogawa FIO module configurations.
Does YOKOGAWA AEA4D support redundant analog modules?
Yes. Yokogawa specifies AEA4D for both single and dual-redundant arrangements, but the permitted module and channel combination must match the official connection table.
Which modules can connect to YOKOGAWA AEA4D?
The official specification lists combinations including AAI135, AAI835 and AAP135 for 8-point × 2 use, and AAI141, AAV141, AAV142, AAV144, AAB841, AAI841, AAV542, AAV544, AAI143 and AAI543 for 16-point × 2 arrangements.
Which cable is used with YOKOGAWA AEA4D?
AEA4D uses Yokogawa KS1 cables for the module combinations documented in the general specification; cable length and connector destination must be confirmed before ordering.
What terminal style does YOKOGAWA AEA4D provide?
The field side uses M4 screw terminals, making terminal-number documentation and correct tightening important during replacement.
How much rack space does YOKOGAWA AEA4D require?
AEA4D is designed for a 19-inch rack, has a 482.6 mm overall width and uses the published 465.1 mm and 440 mm mounting-center dimensions.
What is the approximate weight of YOKOGAWA AEA4D?
The terminal board has an approximate mass of 1.5 kg, so the rack support and mounting screws should be prepared before installation.
Why must unused YOKOGAWA AEA4D connectors remain capped?
Yokogawa instructs users to leave connector caps on unused connectors to prevent dust ingress and physical deformation of the connector pins.
