FC-SAI-1620M Honeywell - Analog Input Module

SAI-1620m Safe High-Density Analog Input Module

Overview: The SAI-1620m analog input module is designed to offer sixteen safe analog input channels (0-4 V) compliant with SIL3 safety class as per IEC 61508 standards. It is ideal for applications requiring high-density and high-safety analog input solutions.

Features:

• Analog Input Channels: Sixteen channels with a 0-4 V input range, supporting various analog signals.
• Isolated Analog 0 V: All sixteen channels share a common isolated analog 0 V.
• Field Signal Conversion: Capable of converting 0-20 mA signals using field termination assembly modules or dedicated analog input conversion modules.
• Self-Test Functionality: Controlled by the Safety Manager Controller, it performs self-tests to ensure absolute accuracy, correct conversion over the full range, checks for crosstalk between inputs, channel input filters, and internal supply voltages.
