Product Overview: AAI143‑H00/A4S00
The AAI143‑H00/A4S00 is an isolated analog input module engineered for use within industrial distributed control systems. It supports 16 channels of 4–20 mA inputs, with the “H00” portion indicating built-in HART communication support and the “A4S00” marking a specific modular form tailored for high-density rack integration. Ideal for compact control cabinets, it balances precision analog data capture with digital diagnostics capability.
