Overview
The Honeywell FC-SAI-1620M belongs to the Safety Manager / FSC series and serves as a high-density analog input module. It supports 16 analog input channels with a 0(4)-20 mA signal range and operates reliably on a 24 VDC supply. Honeywell builds this module for safety-critical control systems that demand precise and consistent analog data.
In addition, the SAI-1620M features sixteen analog inputs (0–4 V) and one external voltage readback input (0–4 V), giving engineers greater flexibility. Because all sixteen channels share an isolated analog 0 V common, the design enhances signal integrity while preventing ground loops.
Moreover, the FC-SAI-1620M complies with SIL 3 safety standards under IEC 61508, which ensures dependable performance in critical environments. Since the field signals must be converted from 0–20 mA to a level suitable for the module, it integrates seamlessly with standard industrial converters. Consequently, this module offers both safety and versatility for demanding process applications.
