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.
