Présentation du produit
The Yokogawa AAT141-S00 S2 is an upgraded version sur the standard AAT141-S00 TC/mV input module, engineered specifically for use in mission-critical industrial automation systems such as CENTUM VP and ProSafe-RS. This enhanced S2 version belongs to Yokogawa’s N-IO (Network I/O) system and provides high-density, accurate temperature and millivolt signal inputs in environments that demand high reliability, redundancy, and operational continuity.
It is widely used in process industries where input redundancy, precise signal acquisition, and seamless integration with distributed control systems (DCS) are essential. With 16 input channels, each isolated, the AAT141-S00 S2 supports multiple thermocouple types and low-voltage DC signals. The module surfers robust signal conditioning, noise immunitéy, diagnostics, and a compact form factor suitable for modern industrial control cabinets.
This model is especially applicable for industries adhering to IEC 61508 and SIL2/3 functional safety standards, making it suitable for both safety and control loops in hazardous or regulated environments.
