Honeywell FC-TSAI-1620M Safety Analog Input Module

Overview

The TSAI-1620m is a Safe 0-20 mA and 4-20 mA Analog Input Field Termination Assembly (FTA) module. It serves as a crucial interface between field components, such as sensors, and the high-density analog input module SAI-1620m in Safety Manager systems. This module is specifically designed for use in Class I, Division 2 hazardous locations, ensuring safe and reliable operation in challenging environments.

Main Functions

The TSAI-1620m module performs three primary functions:

• Signal Conversion: Converts 0(4)-20 mA DC field signals to the signal levels required by the SAI-1620m module.
• Power Supply Distribution: Distributes power to each transmitter with voltage-current limitation, ensuring compliance with hazardous area standards.
• Power Monitoring: Monitors the external power connected to the FTA module.
