Product Overview
The Foxboro P0916AE is an 8-channel Compression Termination Assembly engineered for the FBM203 RTD Input Module in the I/A Series and Foxboro Evo Distributed Control Systems. It provides secure, vibration-resistant termination points for 2-wire or 3-wire Platinum, Nickel, or Copper RTD sensors .
Functioning as a passive DIN rail-mounted component, the P0916AE contains no internal signal processing electronics. All RTD signal conversion and processing is performed by the FBM203 module; the P0916AE simply provides the physical termination interface between field wiring and the FBM via a dedicated termination cable .
The P0916AE is a legacy component that has been superseded by RH916XJ and P0916XJ in newer catalogs . It remains available through aftermarket suppliers for spare-part replacement in existing I/A Series installations. Note: The P0916AE is also referenced in DeltaV Flex.Connect migration solutions as the termination assembly for connecting FBM203 RTD inputs to DeltaV CHARM terminal blocks .
Technical Specifications
Compatible FBM203 Module Specifications
Note: The P0916AE termination assembly is required for field wiring connections but does not include the FBM203 module. Both components are required for a complete RTD input installation.
Key Features & Benefits
Passive Termination Design
The P0916AE contains no active electronics — it is a passive wiring interface that relies entirely on the FBM203 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 P0916AE 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 .
2-Wire and 3-Wire RTD Support
The P0916AE supports both 2-wire and 3-wire RTD configurations. For high-precision applications, 3-wire configurations allow the FBM203 to perform lead-wire resistance compensation, eliminating measurement errors caused by cable resistance .
Modular Architecture for Simplified Maintenance
The FBM203 module can be replaced without disconnecting field wiring from the P0916AE termination assembly. Field wiring remains secured on the P0916AE while the module is swapped, minimizing downtime and reducing the risk of wiring errors during maintenance .
DIN Rail Mounting
The P0916AE 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 .
DeltaV Migration Compatibility
The P0916AE 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 RTD CHARM terminal blocks for 2-wire or 3-wire RTD applications .
Rugged Industrial Construction
The P0916AE is designed for Class G3 (Harsh) environmental conditions, suitable for corrosive chemical plants, coastal installations, and other demanding industrial settings .

Frequently Asked Questions (FAQ)
Q1: Is the P0916AE a PLC module?
No. The P0916AE 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 FBM203 module (RH914SV) is the actual Fieldbus Module that processes RTD signals .
Q2: What is the difference between P0916AE and RH914SV?
P0916AE is the termination assembly (terminal block) that mounts on DIN rail and provides field wiring connections for RTD sensors. RH914SV is the FBM203 module itself — the active Fieldbus Module that performs signal conversion and communicates with the control processor .
Q3: What module does the P0916AE work with?
The P0916AE is designed specifically for the FBM203 RTD input module (8 channels, 0–320 Ω, 2-wire/3-wire RTD). It is not interchangeable with termination assemblies for other FBM types such as FBM201 (analog input), FBM202 (thermocouple), or FBM204 (analog I/O) .
Q4: Does the P0916AE support 4-wire RTDs?
No. The P0916AE supports 2-wire and 3-wire RTD configurations only. For 4-wire RTD applications, a different termination assembly designed for the FBM203d module is required .
Q5: What is the difference between P0916AE and P0916XJ?
P0916AE is the original part number for the compression termination assembly for FBM203. RH916XJ (and P0916XJ) is the superseding part number — a functionally equivalent replacement .
Q6: Can I use a generic 37-pin D-Sub cable instead of the termination cable?
No. The Type-1 termination cable (P0916DC/DD/DE series) has specific pin assignments matched to the FBM203 and P0916AE. Standard 37-pin D-Sub cables have different pinouts and will not work — they may cause signal errors or equipment damage .
Q7: Is the P0916AE still available?
The P0916AE is a legacy component with limited stock availability through aftermarket suppliers. It has been superseded by RH916XJ and P0916XJ in newer catalogs. Availability is typically "New Surplus" or "New Original" stock from authorized distributors .
Q8: Does the P0916AE provide isolation?
The P0916AE itself is a passive component and does not provide isolation. Channel-to-channel and channel-to-ground galvanic isolation is provided by the FBM203 module, which withstands 600 V AC for one minute .
Q9: Can I hot-swap the FBM203 without disconnecting field wiring from the P0916AE?
Yes. The modular architecture allows the FBM203 module to be replaced while leaving field wiring intact on the P0916AE termination assembly. This simplifies maintenance and minimizes downtime .
Q10: Does the P0916AE support DeltaV migration?
Yes. The P0916AE 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 RTD CHARM terminal blocks for 2-wire or 3-wire RTD applications .
Q11: What is the environmental rating of the P0916AE?
The P0916AE is designed for use in Class G3 (Harsh) environments per ISA S71.04, suitable for corrosive chemical plants, coastal installations, and other demanding industrial settings .
Q12: Does this product come with a warranty?
Yes. This offering includes a 1 Year Warranty on the P0916AE termination assembly. Verify warranty terms with your supplier before purchase.
