Description
The Honeywell FS-TSAI-1620M is a Safe Analog Input Field Termination Assembly designed for use with Honeywell Safety Manager systems. It serves as the interface between field-mounted transmitters and the SAI-1620M Safe High-Density Analog Input Module, enabling reliable acquisition of analog process signals in safety-critical applications. The module supports both 0–20 mA and 4–20 mA current loop signals and can be used in safety-related as well as non-safety-related control functions.
The FTA provides sixteen analog input channels arranged in two groups of eight channels with a common 0 V reference. Incoming current signals are converted directly into a 0–4 VDC signal suitable for processing by the SAI-1620M module. This direct linear conversion ensures accurate signal transmission while maintaining the integrity required for Safety Instrumented Systems (SIS).

Features:
- 16-channel safe analog input FTA
- Supports both 0–20 mA and 4–20 mA signals
- Compatible with SAI-1620M Safety Manager modules
- Two groups of eight channels with common 0 V
- Direct conversion from current loop signals to 0–4 VDC
- Integrated transmitter power distribution
- External power supply monitoring
- 315 mA fuse protection
External power can be connected to the module via a 2-pole power screw terminal pair marked 'A' and 'B'. The 0 V connection of the external power is directly connected to the common 0 V of all sixteen analog inputs. The Safety Manager software can monitor the external power voltage via the safe high-density analog input module SAI-1620m.
The FS-TSAI-1620M Honeywell Safe 0-20 mA and 4-20 mA analog input FTA (16 channels) may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

A key function of the FS-TSAI-1620M is integrated transmitter power distribution. The module supplies power to connected field transmitters while simultaneously monitoring the external power source. This arrangement improves system diagnostics and allows rapid detection of power supply abnormalities that could affect measurement reliability.
The module is suitable for interfacing pressure transmitters, temperature transmitters, flow meters, level instruments, analyzers, and other process sensors that utilize industry-standard current loop signals. Its Class I Division 2 suitability allows deployment in industrial environments where hazardous-area requirements must be considered.

Technical notes
The module performs linear direct conversion of 0-20 mA DC and 4-20 mA DC field signals to the signal levels required by the SAI-1620m module. The input circuit of each channel consists of a high-precision 250 Ω resistor which converts the input current (0-20 mA) to the input voltage for the high-density analog input module. The output voltage to the SAI-1620m is 0-5 V DC with a conversion accuracy of 0.1%.
FAQs
-
What is the nominal operating voltage?
+The module operates at a nominal supply of 24 VDC. -
What is the difference between FS-TSAI-1620M and FC-TSAI-1620M?
+FS prefix: Denotes the non-conformal coated version of the module.FC prefix: Denotes the conformal coated ("CC") version. Conformal coating protects the circuitry against harsh industrial environments, moisture, and chemical contaminants. -
How many channels does the module support?
+16 channels: It features 16 analog input channels divided into 2 isolated groups of 8 with a common 0V line. -
Which systems are compatible with the TSAI-1620M?
+It is primarily used within the Honeywell Safety Manager system. It often acts as the field interface component for the redundant safety high-density analog input module (e.g., the Honeywell FC-SAI-1620M).
