Regarding the E69F-T-I2-J-R-S FOXBORO converter (note: usually letters and numbers in the model are not separated by a dash, here I assume you are referring to FOXBORO's E69F-T12-JRS or similar model), the following is a detailed analysis:

1、 Overview

FOXBORO's E69F series converter is a field installed current pneumatic signal converter that can accept standard DC input signals and convert them into proportional pneumatic output signals for use with other pneumatic instruments or control valves. The converter is designed to be compact and small, easy to connect with electrical and pneumatic interfaces, and conveniently installed on surfaces, valve yokes, or vertical pipelines.

2、 Model analysis

E69F: Indicates that the converter belongs to FOXBORO's E69F series.

T12: may indicate a specific technical specification or version of the converter.

JRS: may represent the configuration or additional features of the converter, such as J may represent a specific input/output signal selection, R may represent reverse action, and S may represent a special configuration or standard.

3、 Main features

Compliant with EU directives: The "CE" mark on the product indicates that the converter complies with applicable EU directives.

Compact design: small size, easy to install and connect.

Adequate gap: The current detection motor (or corona motor) in the converter is designed to have a large gap between the coil and the housing, preventing corrosion and dust particles from interfering with the operation of the mechanical device due to atmospheric changes.

Strong adaptability: The converter can choose input and output signals, different input ranges, and direct or reverse actions, making it easy to adapt to various applications.

Output signal optimization: The selection of output signals makes this converter particularly suitable for valve applications.

4、 Technical specifications

Power supply voltage: usually around 10V (specific values may vary depending on the model).

Rated current: may vary by model, but typically around 20A.

Working temperature: A wide range of working temperatures, such as -95 ℃ (some models may vary).

Accuracy: The accuracy of the range may vary depending on the output signal code, such as ± 1.0% or ± 2%.

Linearity: ± 0.5% of the range (typical value, maximum deviation limited by accuracy specifications).

Repeatability: ± 0.25% of the range (typical value, maximum deviation limited by accuracy specifications).

5、 Application

This converter is widely used in industrial automation control systems, especially in situations where current pneumatic signal conversion is required, such as valve control, pneumatic instrument connection, etc.
