Product Profile: Yokogawa AAI143‑S53/A4S00
Product Introduction
The AAI143‑S53/A4S00 is a rugged, sixteen‑channel analog input module engineered for control and instrumentation systems. Designed for industrial environments, it reads 4–20 mA signals with high accuracy, extreme reliability, and strong isolation. The S53 variant supports an extended operating temperature range and is equipped with a pressure‑clamp connection block (A4S00) for secure field wiring. Industry-tested for heavy-duty use, this module ensures long-term stability in temperature-variable, high-interference environments.
It is ideally placed in applications where precise multi-channel signal acquisition and robust physical connections are both critical.
