Overview Manuals Signal Data Diagnostics Compatibility Installation Check

Features:

  • Sixteen safe 0-4.1 V analog input channels
  • Separate external readback for each signal path
  • SIL 3 capability in an approved IEC 61508 configuration
FA-SAI-1620m combines high-channel-density analog acquisition with independent readback supervision.

The selected termination assembly determines loop power, conversion and diagnostics, so module and FTA must be engineered as one solution.

Channel calibration must include transmitter, termination, wiring and application scaling rather than module accuracy alone.

The Honeywell FA-SAI-1620m 16-Channel Safe Analog Input Module is available for quotation and technical support from Apter Power.
Verified resources for FA-SAI-1620m:

Signal Data:

  • Safe analog channels: 16
  • Direct input range: 0-4.1 V
  • External readback range: 0-4.1 V
Use the documented FA-SAI-1620m limits when calculating the complete field circuit.

Diagnostics:

  • Absolute-accuracy and full-range conversion tests
  • Crosstalk and filter supervision
  • Internal-supply and readback checks
Resolve all FA-SAI-1620m channel, wiring and system diagnostics before release to operation.

Compatibility:

  • TSAI-1620m for standard analog loops
  • TSHART, TSGAS and TSFIRE for designated applications
  • BSAI-1620mE for approved conversion arrangements
Match FA-SAI-1620m to the approved Safety Manager module, termination and field-device arrangement.

Installation Check:

  • Confirm FTA and cable allocation
  • Calibrate input and readback paths
  • Prove alarms and trip logic

Description
Honeywell FA-SAI-1620m 16-Channel Safe Analog Input Module provides sixteen safe analog inputs with a separate external readback path for every channel in Honeywell Safety Manager.

Honeywell documents SIL 3 capability within an approved IEC 61508 system. Conversion, readback, crosstalk and internal-supply diagnostics supervise the signal chain, while the complete safety function still requires application validation and proof testing.

Select the TSAI-1620m, TSHART-1620m, TSGAS-1624, TSFIRE-1624 or BSAI-1620mE termination for the actual transmitter. Verify loop power, scaling, cable allocation and readback behavior before commissioning.

Technical notes
FA-SAI-1620m provides sixteen supervised 0-4.1 V analog inputs with independent external readback. Verify the exact field interface and approved system configuration before commissioning.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How are 4-20 mA transmitters connected?
Use an approved TSAI, TSHART or BSAI termination and conversion arrangement, not an unmatched direct loop.
What does the readback path supervise?
It measures the external termination output so Safety Manager can compare the acquired value with the signal chain.
Does SIL 3 apply to FA-SAI-1620m alone?
No. Certification depends on the complete controller, application, diagnostics, field loop and proof testing.
Which hardware must be matched with FA-SAI-1620m?
Verify TSAI-1620m for standard analog loops, TSHART, TSGAS and TSFIRE for designated applications and the approved Safety Manager hardware list before installation.
Which diagnostics are important for FA-SAI-1620m?
Check absolute-accuracy and full-range conversion tests, crosstalk and filter supervision, internal-supply and readback checks and clear every unexplained channel or system alarm.
Can another construction variant replace FA-SAI-1620m?
Only after environmental construction, certifications, hardware revision and project approval have been confirmed.
What commissioning checks are required for FA-SAI-1620m?
Perform these product-specific checks: confirm fta and cable allocation, calibrate input and readback paths, prove alarms and trip logic; document the final results.
What information is needed to quote FA-SAI-1620m?
Provide the exact module model, hardware revision, connected field circuit, required construction, quantity and destination.
