The Foxboro P0926MX is a passive signal splitting/merging module enclosure belonging to the Foxboro I/A Series system of Invensys (now a subsidiary of Schneider Electric). It is typically supplied as a kit that includes 2 core modules. Its primary functions are to split one input signal into multiple output signals or merge multiple input signals into a single output signal. Equipped with signal isolation capability, it can effectively suppress ground potential differences and electromagnetic interference in industrial field environments, ensuring the accuracy and stability of signal transmission. As a key component for signal link expansion and optimization in process automation systems, it is suitable for both analog and digital signal scenarios, and widely used in harsh industrial environments such as petrochemicals, power generation and metallurgy.
Functions and Design Features
Bidirectional Signal Processing: Supports splitting and merging of analog signals (e.g., 4-20mA, 0-10V) and digital signals (e.g., dry/wet contacts, level signals). A single module allows configurable channel counts ranging from 2 to 16, with input/output impedance of 100kΩ–1MΩ, making it compatible with the interfaces of most industrial sensors and controllers.
Industrial-Grade Protective Design: Housed in a compact, rugged metal enclosure with IP30 protection rating, it can operate in temperatures ranging from -20℃ to 60℃ and humidity levels of 10%–90% RH (non-condensing). Its vibration and shock resistance complies with the IEC 60068-2 series standards, and it is suitable for both control room panel mounting and DIN rail mounting.
Isolation and Anti-Interference: Built-in electromagnetic isolation circuits provide isolation voltage of ≥500V AC, which can block ground faults and noise crosstalk in signal loops, ensuring signal accuracy is not affected by on-site working conditions. The passive design eliminates the need for external power supply, reducing system complexity and potential fault points.
Modular Design and Easy Maintenance: The module enclosure supports hot swapping of core modules, enabling maintenance without system shutdown. The terminal blocks adopt spring compression or screw locking design, ensuring secure wiring and facilitating quick replacement, which significantly shortens commissioning and maintenance time.

Application Scenarios
Multi-channel Signal DistributionSplit the 4-20mA signals from pressure/temperature transmitters to multiple destinations simultaneously, including DCS controllers, recorders and Safety Instrumented Systems (SIS). This enables multi-system sharing of the same signal, eliminating the need for redundant sensor deployment.
Signal Merging and AggregationCombine multiple status feedback signals (e.g., valve open/close positions) from parallel control loops into a single signal, which is then connected to PLCs or alarm systems. This simplifies system wiring and the configuration of control points.
System Expansion and RetrofitAddress insufficient I/O channels in legacy DCS systems by extending signal links via this module enclosure, eliminating the requirement to replace core controllers and reducing upgrade costs. It can also be used for signal adaptation between devices of different brands, resolving interface incompatibility issues.
Fault Isolation and DiagnosisLocate fault points in complex signal loops using the module’s isolation capability. When an abnormality occurs in one output channel, it will not affect the normal operation of other channels, improving system fault tolerance and maintenance efficiency.
