Product Short Description
Technical Specifications
- Cable and Termination Parameters
- It features a fixed length of 3 meters, which is equivalent to 9.8 feet, matching the typical distance requirements between field instruments and control cabinets in most industrial installations.
- The cable adopts Type 1 termination, a design recognized for its robust connection performance in industrial environments and its ability to maintain stable contact even under mechanical stress.
- The cable conductor uses high-conductivity copper material, and the insulation layer is made of flame-retardant and wear-resistant PVC, which prevents signal interference and external damage.
- Electrical Performance Parameters
- It supports signal transmission for industrial standard instruments, including 4 – 20mA analog signals and discrete digital signals, compatible with common signal types of pressure transmitters, temperature transmitters, and limit switches.
- It has a rated voltage of 300 volts alternating current, meeting the electrical safety requirements of industrial control circuits, and a maximum current-carrying capacity of 2 amperes to adapt to the power supply needs of small to medium-sized field instruments.
- The cable has a low signal attenuation rate, with a signal loss of less than 0.5% per meter during analog signal transmission, ensuring the accuracy of data collected by the control system.
Description
- Environmental Adaptability Parameters
- The operating temperature range spans from -40°C to 70°C, allowing it to work normally in both low-temperature outdoor equipment areas and high-temperature workshop environments.
- It operates stably in environments with a relative humidity of 0% to 95% without condensation, avoiding insulation failure caused by moisture accumulation.
- It has anti-vibration properties that can withstand continuous vibration in industrial production workshops, and the termination connection remains intact without loosening under standard industrial vibration intensity.
Function Features
- Stable Signal Transmission
The high-quality conductor and insulation materials minimize signal attenuation and electromagnetic interference during transmission. It ensures that analog signals reflecting process parameters and digital signals indicating equipment status are transmitted to the control system accurately and in real time. This stability prevents misjudgments or incorrect control instructions caused by distorted signals, safeguarding the normal operation of the entire production process.
- Durable Connection Structure
The integration of Type 1 termination creates a secure and tight connection between the cable and instruments or control units. This structure resists the effects of mechanical pulling and vibration during long-term industrial operations, avoiding connection loosening that could lead to communication interruptions. It reduces the frequency of maintenance and replacement caused by poor connections and extends the overall service life of the cable assembly.
- Broad Compatibility
The cable assembly is fully compatible with all equipment under Foxboro’s I/A Series distributed control system. It connects seamlessly with various field instruments such as pressure transmitters, temperature transmitters, flow meters, and discrete devices like pushbuttons and limit switches. It eliminates the need for additional adapters or conversion components, simplifying system integration and reducing the cost of equipment configuration.
- Harsh Environment Resistance
The industrial-grade material selection and structural design enable the cable assembly to resist the adverse effects of dust, moisture, and temperature fluctuations in industrial sites. It maintains performance integrity in harsh working conditions where ordinary cables may fail, ensuring uninterrupted signal transmission and providing reliable support for the continuous operation of industrial production lines.
