Product Introduction

The Foxboro P0916AG is a Field Termination Assembly designed for the FBM204 Fieldbus Module in Foxboro I/A Series 200 Series distributed control systems. It provides the physical connection between field instruments and the FBM204 electronics, supporting four analog input channels and four analog output channels.

The P0916AG is a passive termination component. It does not perform signal conversion or execute control logic. The associated FBM204 module handles analog signal processing, while the P0916AG provides organized field wiring termination and signal routing.

Typical applications include process transmitters, control valve positioners, and other 0–20 mA field devices in chemical plants, power stations, refineries, and other facilities maintaining Foxboro I/A Series control systems.

 

Installation & Replacement Guide

 

Stage 1: Pre-Installation Preparation

⚠️ Safety First

Before replacing P0916AG:

1. Confirm the affected FBM204 module and field loops.
2. Notify operations before disconnecting analog signals.
3. Place affected control loops into a safe condition.
4. Isolate external field power where required.
5. Verify the replacement part number.

Required Tools

• ESD wrist strap
• Digital multimeter
• Screwdriver set
• Wire labels
• Camera for wiring documentation

Record Before Removal

Document:

• FBM204 slot location
• Input channel assignments
• Output channel assignments
• Field instrument tags
• Terminal numbering
• Existing alarm conditions

⚠️ Important:
P0916AG must be matched with the correct FBM type. It is not interchangeable with temperature, RTD, digital, or other analog termination assemblies.

 

Stage 2: Removing Existing

Estimated Time: 10–15 minutes

1. Open the Foxboro I/A Series cabinet.
2. Locate the termination assembly.
3. Photograph terminal wiring.
4. Label each field cable.
5. Disconnect field wires.
6. Remove the termination assembly.

Inspect:

• Terminal blocks
• Cable connector
• Mounting hardware
• Signs of overheating or corrosion

 

Stage 3: Installing Replacement

Estimated Time: 15 minutes

1. Confirm:

   Foxboro → compatible

2. Inspect replacement unit:
   • Terminal condition
   • Connector pins
   • Housing integrity
3. Mount the termination assembly.
4. Connect the termination cable to the side.
5. Reconnect field wiring.

Installation Checklist

☐ Correct TA model installed
☐ compatibility confirmed
☐ Input/output channels verified
☐ Field wiring matched
☐ Terminal screws tightened

 

Stage 4: Testing & Commissioning

After installation:

1. Restore system operation.
2. Verify communication.
3. Check analog input values.
4. Test analog output commands.

Recommended checks:

Analog Input Testing

• Apply known current signal.
• Verify engineering value.
• Confirm scaling.

Analog Output Testing

• Command output from control system.
• Measure output current.
• Verify field device response.

 

Troubleshooting Guide

 

Problem: Analog Input Reading Incorrect

Check:

• Input wiring polarity
• Loop power supply
• Channel configuration
• Field transmitter output

 

Problem: Analog Output Device Does Not Respond

Check:

• Output channel assignment
• Control output configuration
• Field device wiring
• Output current measurement

 

Problem: Communication Failure

Check:

• Termination cable connection
• Baseplate seating
• module status
• Controller communication

 

Frequently Asked Questions (FAQ)

Q1: What is Foxboro ?

is a Foxboro I/A Series Field Termination Assembly used for four analog inputs and four analog outputs with 0–20 mA signals.

Q2: Is an active I/O module?

No. is a passive field termination assembly. The module performs the actual signal processing and communication functions.

Q3: Which FBM module uses ?

is designed for the analog input/output interface module.

Q4: What signals does support?

It supports:

• 4 × 0–20 mA analog inputs
• 4 × 0–20 mA analog outputs

The inputs and outputs are independently isolated.

Q5: What is the difference between and P0916AJ?

Both are related to 4 AI / 4 AO analog termination applications.

• Used with non-redundant configuration
• P0916AJ: Used with FBM205 redundant configuration

Verify the installed FBM model before ordering.

Q6: Is Foxboro obsolete?

belongs to the legacy Foxboro I/A Series 200 I/O family. Many facilities continue operating these systems, so replacement termination assemblies remain available through industrial automation spare-part channels.

Q7: What should be checked before purchasing ?

Confirm:

• Part number:
• Associated module:
• Signal type: 0–20 mA
• Channel configuration: 4 AI + 4 AO
• Termination style: Compression
• Existing cable and baseplate compatibility

A similar-looking Foxboro termination assembly may have a different signal assignment and cannot be assumed compatible.
