Honeywell FC-SAI-1620M Safe high-density analog input module (16 channels)

Honeywell FC-SAI-1620M Safe high-density analog input module (16 channels)

Description

The analog input module SAI-1620m has sixteen analog inputs (0-4 V) and an external voltage readback input (0-4 V). The sixteen channels are safe (safety class SIL3, in compliance with IEC 61508) and have an isolated analog 0 V common to all sixteen channels.

The field signals for the analog inputs of the SAI-1620m module need to be converted from 0-20 mA to a level suitable for the SAI-1620m module.

You can perform this conversion in two ways:

1. On the field termination assembly module TSAI-1620m, TSHART-1620m, TSGAS-1624 or TSFIRE1624
2. Analog input conversion module BSAI-1620mE, located on programming connector (Px) on the back of the IO backplane in the 19-inch chassis 

Analog input signals, such as thermocouple or PT-100, can only be used after conversion to 0(4)—20 mA with a dedicated converter (and a TSAI-1620m or BSAI-1620mE module).
