FOXBORO AD908JQ is a dedicated electrical connection
cable specifically designed for the FBM206 (P0916CQ) 8-channel pulse input module in the FOXBORO I/A Series system. As a critical component for signal transmission between the module and field devices, terminal blocks or the system backplane, it adopts an industrial-grade shielding and insulation design, which ensures stable and accurate transmission of pulse signals in complex industrial electromagnetic environments.
It is suitable for collecting sensor pulse signals in scenarios such as flow measurement, metering and weighing, providing reliable physical connection support for the FBM206 module to efficiently perform its signal conversion and transmission functions. This cable serves as an important accessory component for the pulse signal link in the FOXBORO DCS system.
Core Compatibility and Positioning
The AD908JQ cable is an original equipment manufacturer (OEM) dedicated accessory cable for the FBM206 module. As a core pulse input card of the FOXBORO I/A Series Distributed Control System (DCS), the FBM206 module is equipped with 8 independent pulse input channels, which can process pulse signals from field devices such as flowmeters and hopper scales and convert them into digital signals recognizable by the control system.
Customized according to the signal interface definition, electrical characteristics and installation specifications of the FBM206 module, the AD908JQ cable perfectly matches the module’s signal transmission protocol and impedance requirements. It ensures distortion-free signal interaction between the module and external devices, prevents signal attenuation, interference and other issues caused by cable incompatibility, and guarantees the accuracy and real-time performance of system data acquisition.
Key Technical Features
Signal Transmission Performance
The cable adopts stranded tinned copper conductors, featuring low resistance and high conductivity, which can effectively reduce signal loss during pulse signal transmission. It is compatible with the wide-frequency pulse signal input range supported by the FBM206 module, meeting the pulse output rate requirements of different field devices.
Meanwhile, integrated with a high-density insulating layer, it reduces inter-wire capacitance and crosstalk, ensures the independence of multi-channel signal parallel transmission, and keeps the 8-channel pulse signals free from mutual interference, enabling the acquisition accuracy to reach the module’s nominal error range of ±0.5%.
Anti-interference Capability
It employs a double-layer shielding structure, consisting of an inner aluminum foil shield and an outer tinned copper braided shield with high shielding coverage. This structure can effectively resist electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial sites, making it particularly suitable for signal transmission in high-interference environments with frequency converters and high-power motors. It ensures the integrity of pulse signals and avoids problems such as miscounting that may affect production process control.
Physical and Environmental Compatibility
The cable sheath is made of industrial-grade PVC or polyurethane material, featuring wear resistance, oil resistance, acid and alkali resistance, and anti-aging properties, which allows it to adapt to harsh industrial environments such as factory workshops and chemical parks.
Its rated operating temperature ranges from -40℃ to 85℃, enabling stable operation in high and low temperature conditions. With moderate flexibility, the cable’s minimum bending radius complies with industrial installation standards, facilitating wiring in cabinets and connection of field devices, and improving installation convenience and flexibility.
Safety and Reliability
The cable has obtained industrial safety certifications including UL and CE. It boasts excellent insulation performance between conductors and sheaths, with insulation resistance and withstand voltage values complying with the electrical safety specifications of the FOXBORO I/A Series system, which can effectively prevent potential safety hazards such as short circuits and electric leakage.
Moreover, it uses crimp terminals or special connectors, ensuring a firm and reliable connection with the FBM206 module and field devices. The plugging and unplugging cycles and contact stability meet the requirements of long-term industrial operation, reducing maintenance frequency and fault risks.
Application Scenarios and Installation Guidelines
Typical Application Scenarios
This cable is mainly applied in the FOXBORO I/A Series DCS systems across industries such as petrochemicals, food processing, pharmaceuticals, and electric power. It serves to connect the FBM206 pulse input module to various pulse-output field devices. For instance, in crude oil transmission pipelines, it links electromagnetic flowmeters with the FBM206 module to enable real-time flow data acquisition; in the material metering process of pharmaceutical production, it connects the pulse output terminal of hopper scales to the module, ensuring batching accuracy. These applications facilitate precise control and data traceability of industrial processes.
Installation and Operation Precautions
- Ensure the cable length is suitable for the on-site routing distance during installation. Avoid excessive length that may cause signal attenuation or insufficient length that hinders installation operations. Meanwhile, reserve an appropriate redundant length to facilitate future maintenance.
- Maintain a safe distance from power cables during routing and avoid parallel laying. If crossing is inevitable, adopt a perpendicular crossing method to further reduce interference risks.
Verify the pin definitions when connecting the module and devices to ensure correct correspondence between positive/negative poles and signal channels. Tighten the connectors or terminals to prevent poor contact. After installation, use the diagnostic function of the FBM206 module to check the signal transmission status and confirm the cable connection is normal.
Ordering and Compatibility Instructions
As a dedicated accessory cable for the FBM206 module, the AD908JQ must be ordered to match the FBM206 (P0916CQ) module model. It is compatible with all versions of racks and controllers in the FOXBORO I/A Series system and can work collaboratively with other cards and communication components in the system, providing users with a complete pulse signal acquisition solution. Meanwhile, FOXBORO offers original factory technical support and quality assurance for this cable, ensuring long-term stable and compatible operation of the product and the system.
