Honeywell SAI-1620M CCV1.5 Analog Input Module

The SAI-1620M CCV1.5 is a high-density analog input module manufactured by Honeywell for industrial automation and safety instrumented systems. This hardware unit provides precise signal acquisition across 16 channels, supporting critical process monitoring applications. Designed to meet stringent safety requirements, it achieves a SIL3 safety rating in compliance with IEC 61508 standards.

Channel Configuration and Signal Conversion

The module features 16 analog input channels rated for a 0-4V input range, accompanied by a single external voltage readback channel operating within the same 0-4V span. To process standard 0-20mA field instrumentation signals, external conversion modules must be utilized to translate current loops into the 0-4V input voltage range supported by the hardware. All channels share an isolated analog 0V common reference to maintain signal integrity.

Environmental Specifications

Engineered for reliable deployment within industrial control cabinets, the module operates across an ambient temperature range of -10 deg C to +55 deg C. For storage conditions, it withstands temperatures ranging from -40 deg C to +70 deg C, ensuring durability during warehousing and transit.
