About the Product

Honeywell FC-SAI-1620m Safe High-Density Analog Input Module

The Honeywell FC-SAI-1620m is a high-density analog input module designed for safety-critical industrial systems. It provides sixteen safe analog input channels (0-4 V) and complies with SIL3 safety standards according to IEC 61508. This module ensures accurate signal conversion, low crosstalk, and continuous self-test functionality for system integrity.

Key Features

  • Sixteen analog input channels with 0-4 V range for precise measurements
  • Common isolated analog 0 V across all channels
  • Supports field signal conversion from 0-20 mA using FTAs or dedicated analog input modules
  • Self-test functions controlled by Honeywell Safety Manager Controller
  • Monitors conversion accuracy, input filters, internal voltages, and crosstalk between channels
  • Compact dimensions: 4 TE × 3 HE (4 HP, 3U) for efficient chassis installation
  • Key coding ensures proper integration with Honeywell chassis modules
  • High input resistance (>1 MΩ) and 12-bit A/D conversion with ±1 LSB inaccuracy
  • Maximum load capacitance: 100 nF, absolute maximum input signal: ±36 V DC
  • Crosstalk between channels >60 dB for reliable analog measurement
  • External voltage readback: 0-4.1 V with typical 1 MΩ input resistance

Power Requirements

  • 5 V DC: 35 mA
  • 24 V DC: 35 mA

The Honeywell FC-SAI-1620m module provides a reliable and safe solution for high-density analog input in SIL3-compliant industrial systems. Its design ensures operational safety, accurate monitoring, and seamless integration with Honeywell control systems.
