Product Overview

The Honeywell FC-UGAI01 is a SIL 2 rated single-channel galvanically isolated analog input barrier designed for Honeywell’s Universal Marshalling Solution for Safety Systems.

The module is designed to interface field-side analog signals with the safety system while providing electrical isolation between the field circuit, system side and power. It supports 4–20 mA signals with HART communication and is intended for use with the CC-UGIA01 intrinsic safety signal conditioning backplane.

The FC-UGAI01 is particularly useful in safety applications where field instruments are installed in hazardous areas and the analog signal must be transferred to a safety control system while maintaining the required isolation and intrinsic-safety interface.

Rather than being a conventional DCS analog input card, the FC-UGAI01 functions as a signal-conditioning and isolation barrier between field instrumentation and the control or safety system.

Key Features

The Honeywell FC-UGAI01 provides several functions for industrial safety signal interfacing:

1. Single-channel analog input
2. 4–20 mA signal support
3. HART communication support
4. Galvanic isolation
5. Three-way isolation
6. SIL 2 safety rating
7. Reverse polarity protection
8. Field-side open-wire fault transparency
9. Intrinsic safety interface
10. 24 VDC power supply
11. DIN-rail compatible baseplate installation
12. Mechanical keying for mistake-proof installation

Honeywell identifies the FC-UGAI01 as an SIL 2 Analog Input Barrier within its Universal Marshalling Solution for Safety Systems.

 

4–20 mA and HART Signal Interface

The FC-UGAI01 is designed for industrial analog instrumentation using the standard 4–20 mA current loop.

It can support HART-enabled field instruments, allowing the analog process signal to be transferred while maintaining HART communication capability.

The module supports different field-side wiring arrangements depending on the application. These include:

1. Two-wire current-source configuration
2. Three-wire current-source configuration
3. Two-wire / four-wire current-sink configuration

For the two-wire current-source configuration, the field terminals A(+) and B(-) are used. For the three-wire current-source configuration, A(+), B(-) and C are used. Honeywell documentation also specifies the B(-) and C arrangement for the applicable current-sink configuration.

This flexibility allows the FC-UGAI01 to be used with different types of 4–20 mA field instrumentation.

Galvanic Isolation

One of the most important characteristics of the FC-UGAI01 is its galvanic isolation.

The barrier separates the field-side signal from the safety-system side, helping prevent unwanted electrical interaction between the two circuits.

Honeywell specifies 1500 VAC isolation between the power/DCS side and field side. This isolation is particularly important when field instruments are located in hazardous or electrically demanding industrial environments.

The isolation architecture also contributes to improved protection of the control system against field-side electrical disturbances and potential ground-related problems.

 

Intrinsic Safety Applications

The FC-UGAI01 is intended for use as an intrinsic-safety analog input barrier within Honeywell’s Universal Marshalling architecture.

It is installed with the CC-UGIA01 backplane, which provides the field-side terminal interface and system-side connection to the safety system. Honeywell documentation identifies the CC-UGIA01 as the compatible intrinsic-safety backplane for FC-UGAI01 installations.

This arrangement allows field wiring from hazardous areas to be terminated at the marshalling assembly while the FC-UGAI01 provides the required signal isolation and conditioning.

The architecture is especially useful in safety systems where large numbers of field signals need to be marshalled in a standardized cabinet arrangement.

 

Connection to Honeywell Safety Systems

The FC-UGAI01 does not normally operate as a standalone DCS I/O card.

It forms part of a larger Universal Marshalling Solution architecture.

A typical signal path can be represented as:

Field Instrument → CC-UGIA01 Field Terminals → FC-UGAI01 Barrier → CC-UGIA01 System Interface → SIC Cable / System I/O → Honeywell Safety System

The Honeywell Universal Marshalling Solution is designed to standardize field termination and signal conditioning while reducing the need for traditional point-to-point marshalling arrangements. Honeywell identifies the solution for deployment across process, safety, PLC and UOC applications.
