Honeywell SAI-1620M CC V1.2 Safe Analog Input Module

The SAI-1620M CC V1.2 (often cataloged with the prefix FC-SAI-1620M) is a high-density safe analog input module designed for Honeywell Safety Manager and Experion PKS industrial safety architectures. This hardware unit provides precise signal acquisition across 16 independent channels while meeting rigorous functional safety standards for emergency shutdown and critical process monitoring. The "CC" designation indicates that the module features conformal coating, making it resilient in corrosive or harsh industrial environments.

Architecture and Input Processing

The module features 16 input channels engineered to handle precision sensor inputs within a 0 to 4.1 V range. It incorporates a 12-bit Analog-to-Digital (A/D) converter to ensure high-resolution conversion accuracy for safety loops. To integrate standard 0-20 mA field signals, external conversion components or dedicated termination assemblies are typically used to map current loops into the voltage range supported by the hardware.

Hardware Specifications and Power Requirements

Built on a standard European instrument card format, the module requires 4 TE of width and 3 HE (3U) of height within a standard I/O chassis. It interfaces via a 32-pin DIN 41612F backplane connector. The unit draws power from dual internal rails, consuming 35 mA from the 5 Vdc supply and 35 mA from the 24 Vdc supply.
