Product Overview
The Foxboro P0916AG is a Compression Terminal Assembly engineered specifically for the FBM204 analog I/O module in the I/A Series and Foxboro Evo control systems. It provides a high-integrity, organized interface for wiring 0–20 mA or 4–20 mA DC signals from the control system to field devices such as actuators, valves, and positioners .
Functioning as a passive DIN rail-mounted component, the P0916AG contains no internal circuits or signal processing electronics. All analog signal conversion and processing is performed by the FBM204 module; the P0916AG simply provides the physical termination point for field wiring and the electrical interface to the FBM via a dedicated termination cable .
The P0916AG is widely deployed in oil and gas, chemical processing, power generation, and water treatment facilities as part of legacy I/A Series installations. Note: This is a legacy component with limited stock availability through aftermarket suppliers .
Technical Specifications
Key Features & Benefits
Passive Termination Design
The P0916AG contains no active electronics — it is a passive wiring interface that relies entirely on the FBM204 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 P0916AG 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 .
Clear Terminal Labeling
The P0916AG features clearly labeled terminals for each input and output channel, reducing wiring errors during initial installation and simplifying maintenance and troubleshooting activities .
Modular Architecture for Simplified Maintenance
The FBM204 module can be replaced without disconnecting field wiring from the P0916AG termination assembly. Field wiring remains secured on the P0916AG while the module is swapped, minimizing downtime and reducing the risk of wiring errors during maintenance .
DIN Rail Mounting
The P0916AG mounts on standard DIN rail, allowing flexible placement within the control cabinet. This enables the termination assembly to be mounted in either the enclosure or an adjacent enclosure, depending on cabinet layout and space constraints .
Hazardous Location Certification
The P0916AG is UL/UL-C listed for use in Class I, Division 2, Groups A-D, T4 hazardous locations and is DEMKO certified as EEx nA IIC T4 for use in Zone 2 potentially explosive atmospheres .
DeltaV Migration Compatibility
The P0916AG termination assembly supports DeltaV Flex.Connect solutions for migration from Foxboro I/A Series to DeltaV systems. It provides direct connection from the I/A Series 200 termination assembly to DeltaV CHARM terminal blocks for 4–20 mA AI and AO applications .

Frequently Asked Questions (FAQ)
Q1: Is the P0916AG a PLC module?
No. The P0916AG is a Field Terminal Assembly (TA) — a passive wiring interface, not an active PLC module. It contains no processing electronics and performs no signal conversion. The FBM204 module (P0916DC) is the actual Fieldbus Module that processes analog signals .
Q2: What is the difference between P0916AG and P0916DC?
P0916AG is the termination assembly (terminal block) that mounts on DIN rail and provides field wiring connections. P0916DC is the Type-1 termination cable (3 m, 37-pin D-Sub) that connects the P0916AG termination assembly to the FBM204 module baseplate. Both are required for a complete installation .
Q3: What module does the P0916AG work with?
The P0916AG is designed specifically for the FBM204 analog I/O module (4 AI + 4 AO, 0–20 mA). It is not interchangeable with termination assemblies for other FBM types such as FBM201, FBM202 (thermocouple), FBM203 (RTD), or digital I/O modules. Using the wrong TA will cause output abnormalities or loop damage .
Q4: Can I use a generic 37-pin D-Sub cable instead of the P0916DC?
No. The Type-1 termination cable (P0916DC/DD/DE) has specific pin assignments matched to the FBM204 and P0916AG. Standard 37-pin D-Sub cables have different pinouts and will not work — they may cause signal errors or equipment damage .
Q5: Is the P0916AG still available?
The P0916AG is a legacy component with limited stock availability through aftermarket suppliers. Original manufacturer production has been discontinued. Availability is typically "New Surplus" or "New Original" stock from authorized distributors .
Q6: What is the difference between P0916AG and P0916AH?
P0916AG uses compression screw terminals for field wiring. P0916AH uses ring lug terminals. Both are electrically equivalent and compatible with the FBM204; the choice depends on field wiring termination preferences .
Q7: Does the P0916AG provide isolation?
The P0916AG itself is a passive component and does not provide isolation. Channel-to-channel and channel-to-system galvanic isolation is provided by the FBM204 module. The TA simply passes signals through to the module .
Q8: Can I hot-swap the FBM204 without disconnecting field wiring from the P0916AG?
Yes. The modular architecture allows the FBM204 module to be replaced while leaving field wiring intact on the P0916AG termination assembly. This simplifies maintenance and minimizes downtime .
Q9: What certifications does the P0916AG hold?
The P0916AG is UL/UL-C listed for Class I, Division 2, Groups A-D, T4 hazardous locations and DEMKO certified as EEx nA IIC T4 for Zone 2 potentially explosive atmospheres .
Q10: Does this product come with a warranty?
Yes. This offering includes a 1 Year Warranty on the P0916AG termination assembly. Verify warranty terms with your supplier before purchase.
Q11: Can the P0916AG be used for DeltaV migration?
Yes. The P0916AG 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 CHARM terminal blocks for 4–20 mA AI and AO applications .
Q12: What are typical applications for the P0916AG?
The P0916AG is used as the field wiring interface for FBM204 modules in: process control valve positioners in chemical plants, analog transmitter connections in oil and gas facilities, boiler control loops in power generation stations, and analog instrumentation in water treatment systems .
