Description

Foxboro P0926JMA I/A Series Heavy-Duty Clamp Base Module

The P0926JMA is a high-precision mounting and interface baseplate for the Foxboro I/A Series, providing a rugged stainless steel platform for the secure installation of industrial transmitters, controllers, and relays.

Technical Operational Overview

The P0926JMA functions as a fundamental structural and electrical interface within the Foxboro I/A Series ecosystem. This clamp base module provides a stable foundation for a variety of field instruments, ensuring that sensitive controllers and transmitters maintain a secure connection to the control architecture. Constructed from high-grade stainless steel, the unit resists mechanical vibration and chemical corrosion, which are common in heavy industrial settings. The module operates on a standard 24 VDC power supply and maintains an extremely efficient 100 mA current draw, allowing for high-density hardware deployments without overloading power subsystems.

Beyond physical mounting, the P0926JMA facilitates high-accuracy signal processing. It supports a standardized 4-20 mA output with a rapid 1-second response time, enabling real-time process monitoring. With a precision rating of ±0.25% of full scale and a repeatability of ±0.05%, this module ensures that critical data remains consistent across long-term operations. Furthermore, the baseplate is engineered for hazardous environments, carrying Class 1, Division 2 certifications (Groups A-D), which allows for safe integration into volatile areas within refineries and chemical plants.
