Product Overview
The YOKOGAWA AAI543-H50/K4A00 is a Safety Analog Input Module designed for use in Safety Instrumented Systems (SIS). This high-integrity component ensures highly accurate and reliable measurements of analog field signals, which is crucial for meeting stringent safety requirements. Certified for a high safety integrity level (e.g., TÜV SIL3), it provides a robust safety barrier. The module features 16 isolated analog input channels, making it ideal for safety-critical applications, where precision and reliability are paramount.
The suffixes are significant:
-
AAI543: Indicates the base module type (16-channel isolated analog input).
-
-H50: Specifies the input signal range
-
/K4A00: Denotes a version with Safety Functionality or high-reliability coating, making it suitable for SIS applications.
