Product Description
The AAI143 (P/N: AAI143-H03 S1) is a 16-channel high-density analog input module for the Yokogawa CENTUM VP and CS 3000 control systems. Each channel is fully isolated, providing galvanic separation to protect system logic and eliminate ground loops.
As an H-suffix module, it supports HART digital communication, enabling remote diagnostics and asset management for smart field devices. The H03 configuration features ISA Standard G3 conformal coating for corrosion resistance and an extended operating range of -20 to 70 °C, making it ideal for harsh industrial environments. This S1 revision, manufactured in Japan, ensures reliable performance in corrosive or thermally volatile areas.

FAQ
Is the AAI143 an input or output module?
-
The AAI143 is an Analog Input module. Despite some vendor listings as "I/O," it specifically handles 16 input channels.
What is the benefit of the G3 (03) option?
-
The G3 conformal coating protects internal components from corrosive airborne contaminants (ISA-S71.04 standard), preventing premature failure of copper and silver contacts in harsh industrial environments.
