FOXBORO L0130AD L0130AE-0H Circuit power supply analog signal conditioning module

Description

FOXBORO L0130AD L0130AE-0H is a loop power supply analog signal conditioning module used as an interface between field equipment and control systems. L0130AD serves as a two-wire circuit isolator, converting the 4-20 mA signal of the transmitter into an isolated output for DCS use; As a signal conditioner supporting HART communication, L0130AD L0130AE-0H can achieve bidirectional data exchange with intelligent field devices. Both modules belong to Foxboro’s extensive portfolio of I/O and signal conditioning solutions, compatible with the I/A series and EcoStruxure Automation Expert system.

L0130AD L0130AE-0H

In the control system architecture, these modules are located at the field level, serving as bridges between sensors/actuators and central processing units. Its core value lies in:
Electrical isolation: protects the control system from electrical surges and grounding loops.
Signal conditioning: Amplify, filter, and linearize signals to achieve precise process monitoring.
HART compatibility (L0130AE-0H): Supports configuring and diagnosing smart devices without interrupting analog control loops.
For integrators, this means reducing troubleshooting time, improving system uptime, and being compatible with both traditional and modern control settings.

L0130AD L0130AE-0H

Main features and advantages:
functional performance
Circuit power supply design: Obtain power from the 4-20 mA circuit without the need for a separate power source, simplifying installation in remote or space limited environments.
High precision: Maintain a linearity of ± 0.1% to ensure accurate representation of process variables such as temperature, pressure, or flow rate.
HART transparent transmission (L0130AE-0H): Supports the HART protocol on the secondary side, allowing engineers to access device diagnostics and configuration parameters without interrupting the analog control loop.
hardware design
Durable casing: suitable for industrial environments, with a working temperature range of -20 ° C to+60 ° C, dust-proof, moisture-proof, and vibration proof.
Compact structure: Can be installed on standard DIN rails, suitable for dense control panels or on-site installation of junction boxes.
LED diagnosis: The front panel indicator lights display power, signal status, and HART communication (L0130AE-0H) for quick troubleshooting.
compatibility
Protocol independence: Suitable for standard 4-20 mA analog signals and HART enabled devices, suitable for retrofitting old systems or integrating with modern smart sensors.
System integration: seamlessly paired with Foxboro FBM (fieldbus module) racks and other I/A series components to reduce engineering complexity.
reliability
Electrical isolation: A 250 V rms isolation barrier can prevent voltage spikes and extend the service life of on-site equipment and control system components.
Low power consumption: usually ≤ 1.5 W, reducing heat generation and energy consumption in large-scale deployment.
