Product Short Description
Product Overview: The AAI143-H53 S1 is a high-performance 16-channel isolated analog input module designed for safe and accurate signal acquisition in industrial control systems. It supports 4-20 mA current input with HART communication capability for advanced diagnostics and device integration. The “H53” suffix indicates HART support and ISA Standard G3 coating for harsh environments; “S1” denotes the specific suffix code for pressure clamp terminal, MIL connector, and KS cable.
