Product Overview

The Foxboro P0916AA is an 8-channel Compression Termination Assembly engineered specifically for the FBM201 Analog Input Module in the I/A Series 200 and Foxboro Evo Distributed Control Systems. It provides secure, vibration-resistant termination points for eight isolated 0–20 mA (4–20 mA) analog input channels .

Functioning as a passive DIN rail-mounted component, the P0916AA contains no internal signal processing electronics. All analog signal conversion, analog-to-digital conversion, and communication are performed by the FBM201 module; the P0916AA simply provides the physical termination interface between field wiring and the FBM via a dedicated termination cable .

The P0916AA is a legacy component that has been discontinued by the manufacturer. It remains available through aftermarket suppliers as new original or new surplus stock for spare-part replacement in existing I/A Series installations. It is also referenced in DeltaV Flex.Connect migration solutions as the termination assembly for connecting FBM201 4–20 mA inputs to DeltaV CHARM terminal blocks .

Note: The P0916AA termination assembly is required for field wiring connections but does not include the FBM201 module. Both components are required for a complete analog input installation.

Key Features & Benefits

Passive Termination Design

The P0916AA contains no active electronics — it is a passive wiring interface that relies entirely on the FBM201 module for signal processing . This design eliminates a potential failure point, as there are no internal circuits to degrade or malfunction.

Compression Terminal Technology

The P0916AA utilizes compression screw terminals designed to provide gas-tight, vibration-resistant connections that eliminate the need for periodic retorquing. The terminal blocks support multiple insertion and removal cycles, ensuring durability for facilities with frequent upgrades or re-instrumentation .

Purpose-Built for 4–20 mA Analog Signals

The P0916AA is specifically designed for 4–20 mA analog signal transmission. It is optimized for interfacing pressure, flow, and level transmitters into the DCS, providing stable signal routing for continuous process monitoring . It is NOT compatible with thermocouple inputs — thermocouple applications require a specialized assembly with cold-junction compensation .

Modular Architecture for Simplified Maintenance

The FBM201 module can be replaced without disconnecting field wiring from the P0916AA termination assembly. Field wiring remains secured on the P0916AA while the module is swapped, minimizing downtime and reducing wiring error risk. The termination cable connecting the TA to the FBM baseplate is easily removable .

DIN Rail Mounting with Flexible Cable Lengths

The P0916AA mounts on standard DIN rail, allowing flexible placement within the control cabinet. Termination cables are available in lengths up to 30 meters (98 feet), enabling the termination assembly to be mounted in either the enclosure or an adjacent enclosure .

DeltaV Migration Compatibility

The P0916AA termination assembly supports DeltaV Flex.Connect solutions for migration from Foxboro I/A Series to DeltaV systems. It enables direct connection from the I/A Series 200 termination assembly to DeltaV 4–20 mA AI CHARM terminal blocks .

Frequently Asked Questions (FAQ)

Q1: Is the P0916AA a PLC module?

No. The P0916AA is a Termination Assembly (TA) — a passive wiring interface, not an active PLC module. It contains no processing electronics and performs no signal conversion. The FBM201 module (P0914SQ) is the actual Fieldbus Module that processes analog input signals .

Q2: What is the difference between P0916AA and P0914SQ?

P0916AA is the termination assembly (terminal block) that mounts on DIN rail and provides field wiring connections for 4–20 mA sensors. P0914SQ is the FBM201 module itself — the active Fieldbus Module that performs analog signal conversion and communicates with the control processor .

Q3: What module does the P0916AA work with?

The P0916AA is designed specifically for the FBM201 Analog Input Module (8 channels, 0–20 mA). It is not interchangeable with termination assemblies for other FBM types such as FBM202 (thermocouple), FBM203 (RTD), or digital I/O modules .

Q4: Can the P0916AA provide power to 2-wire transmitters?

Yes. The P0916AA distributes loop power from the system backplane when used with an FBM201 module. This allows direct connection of 2-wire 4–20 mA transmitters without requiring separate external power supplies .

Q5: Is the P0916AA compatible with thermocouple inputs?

No. The P0916AA is optimized for current loop (4–20 mA) applications only. Thermocouple applications require a specialized assembly with cold-junction compensation (such as P0916AT) .

Q6: What is the difference between P0916AA and P0916AB?

P0916AA uses compression screw terminals for field wiring. P0916AB uses ring lug terminals. Both are electrically equivalent and compatible with the FBM201; the choice depends on field wiring termination preferences .

Q7: What is the difference between P0916AA and P0916XG?

P0916AA is made of PVC (Polyvinyl Chloride) rated for -20°C to +50°C. P0916XG is made of Polyamide (PA) rated for -20°C to +70°C, providing a higher temperature rating for more demanding environments .

Q8: Is the P0916AA still available?

The P0916AA is a legacy component that has been discontinued by the manufacturer. It remains available through aftermarket suppliers as new original or new surplus stock for spare-part replacement in existing I/A Series installations .

Q9: Can I hot-swap the FBM201 without disconnecting field wiring from the P0916AA?

Yes. The modular architecture allows the FBM201 module to be replaced while leaving field wiring intact on the P0916AA termination assembly. The termination cable can be disconnected from the baseplate, allowing module replacement without disturbing field connections .

Q10: Does the P0916AA support DeltaV migration?

Yes. The P0916AA termination assembly supports DeltaV Flex.Connect solutions for migration from Foxboro I/A Series to DeltaV systems. It enables direct connection from the I/A Series 200 termination assembly to DeltaV 4–20 mA AI CHARM terminal blocks .

Q11: What certifications does the P0916AA hold?

The P0916AA is UL/UL-C listed for ordinary location safety standards and CENELEC certified. It is listed to comply with applicable ordinary location safety standards for fire and shock hazards .

Q12: Does this product come with a warranty?

Yes. This offering includes a 1 Year (12-month) Warranty on the P0916AA termination assembly. Verify warranty terms with your supplier before purchase .

Q13: What is the complete configuration for an analog input loop?

A complete FBM201 analog input loop requires:

• FBM201 module (P0914SQ)

• P0916AA termination assembly (this product)

• Type-1 termination cable (e.g., P0916DC, 3 m)

• Field transmitter wiring (4–20 mA)
