Honeywell FC-SAI-1620M is a smart Analog Input Module, typically for Experion PKS DCS. It has 16 channels supporting 4-20mA/0-10V signals, offers ±0.1% full-scale accuracy, features opto-isolation and fault diagnostics (open/short), works at -40°C to +70°C, meets UL/CE, ensuring reliable industrial process parameter monitoring.
★Description:The analog input module SAI-1620m features sixteen analog inputs (0–4 V) and one external voltage readback input (0–4 V). The sixteen channels are safety-rated (SIL3, compliant with IEC 61508) and share an isolated analog 0 V common across all sixteen channels.
Field signals for the SAI-1620m’s analog inputs—originally 0–20 mA—require conversion
to a level compatible with the module. This conversion can be performed in two ways:•
Via field termination assembly modules: TSAI-1620m, TSHART-1620m, TSGAS-1624, or
TSFIRE-1624• Via the analog input conversion module BSAI-1620mE, which is mounted
on the programming connector (Px) at the rear of the I/O backplane in 19-inch chassis
Additionally, analog input signals such as those from thermocouples or PT-100 sensors
can only be used with the SAI-1620m after first being converted to 0(4)–20 mA via a
dedicated converter—alongside either a TSAI-1620m or BSAI-1620mE module.
★Function:The FC-SAI-1620M is a 16-channel analog input (AI) module engineered for industrial automation systems, typically integrated into distributed control systems (DCS) or industrial I/O chassis (e.g., FC-IOCHAS series) to enable reliable acquisition of process-critical analog signals from field devices. Its core function is to receive, condition, and convert standard industrial analog signals—primarily 4–20 mA DC current signals and 0–10 V DC voltage signals, commonly output by field transmitters (e.g., pressure, temperature, flow, or level transmitters)—into high-precision digital data, which is then transmitted to the central controller for real-time process monitoring and control.
To ensure measurement accuracy and signal integrity in harsh industrial environments (e.g., oil & gas, chemical processing, power generation), the module includes built-in signal conditioning features: electromagnetic interference (EMI) filtering to suppress noise from industrial equipment, signal linearization to correct for sensor non-linearity, and precision amplification to enhance weak input signals. It also incorporates galvanic isolation between channels and from the system communication bus, preventing ground loops and voltage transients from corrupting data or damaging internal components.
Additionally, the FC-SAI-1620M supports HART communication protocol (where compatible) to enable simultaneous transmission of primary process data and secondary diagnostic information (e.g., sensor drift, wiring open circuits, or over-range conditions), facilitating proactive maintenance. It includes built-in self-diagnostics (e.g., module power fault detection, channel status monitoring) that send real-time alerts to the control system, minimizing unplanned downtime. Seamlessly compatible with high-speed industrial buses (e.g., EtherNet/IP), it acts as a critical bridge between field-level sensing devices and the control layer, ensuring accurate, consistent data flow to support efficient industrial process management.

Technical data
Key Features
ψSafety Compliance & Rating
Achieves SIL3 safety certification in accordance with the IEC 61508 standard, making it suitable for critical industrial applications where reliable, safety-focused analog signal acquisition is required (e.g., process control in oil & gas, chemical, or power sectors).
ψAnalog Input Configuration
Features 16 independent analog input channels (0–4 V range) plus 1 dedicated external voltage readback input (0–4 V), enabling simultaneous acquisition of multiple low-voltage analog signals for real-time process monitoring.
ψIsolation Design
Incorporates an isolated analog 0 V common terminal shared across all 16 input channels, effectively reducing electromagnetic interference (EMI) and ground loops to ensure stable, accurate signal measurement in harsh industrial environments.
ψSignal Compatibility with Conversion Support
Designed to work with 0–20 mA field signals (via conversion) and analog signals from sensors like thermocouples or PT-100 RTDs (after conversion to 0(4)–20 mA using a dedicated converter). Conversion can be implemented via compatible field termination assemblies (TSAI-1620m, TSHART-1620m, TSGAS-1624, TSFIRE-1624) or the BSAI-1620mE analog input conversion module (mounted on the Px programming connector of the 19-inch chassis I/O backplane).
ψSystem Integration
Seamlessly compatible with Honeywell’s industrial control ecosystems (e.g., Experion PKS or related I/O architectures), ensuring smooth communication with controllers and facilitating centralized configuration, monitoring, and data logging via supporting software.
ψReliable Performance
Delivers high measurement accuracy and linearity for low-voltage analog signals, minimizing signal distortion and ensuring consistent data quality for critical process control decisions.
