Description
Foxboro RH914YZTechnical Specifications
Rated voltage is three hundred volts alternating and direct current. Current capacity is ten amperes per circuit. Operating temperature ranges from minus forty degrees Celsius to plus eighty-five degrees Celsius. The connection system utilizes spring-cage terminal technology for secure and maintenance-free wire fastening.
Functional Features
Features integrated short-circuit protection mechanisms. Provides isolated grounding paths to prevent signal interference. Supports high-density wiring configurations, significantly reducing panel space requirements and simplifying cable management.
Application Scenarios
Deployed extensively in petrochemical plants, power generation facilities, and water treatment plants. Utilized in process control cabinets for connecting analog transmitters, digital switches, and control actuators to the central processing units.
Performance Parameters
Insulation resistance exceeds one thousand megohms. Dielectric strength is fifteen hundred volts alternating current for one minute. Vibration resistance fully conforms to international electromechanical standards.
Material Composition
The external housing is constructed from high-grade, flame-retardant polyamide. Internal terminal contacts are manufactured from tin-plated copper alloy, ensuring excellent electrical conductivity and long-term corrosion resistance.
Structural Characteristics
Modular design with a snap-on standard rail mounting capability. Incorporates a finger-safe protective front cover to prevent accidental electrical shocks during maintenance operations.
Working Principle
Serves as a physical interface and direct signal router. Field wires are secured to the terminal block, which routes the electrical signals to the Fieldbus Module connector via an internal printed circuit board, maintaining signal fidelity.
Installation Requirements
Must be mounted on standard thirty-five-millimeter rails. Ensure a minimum spacing of fifty millimeters between assemblies for adequate heat dissipation and wire dressing. Use crimp ferrules for all stranded wires.
Usage Precautions
Do not exceed the specified voltage and current ratings under any circumstances. Ensure all connections are torqued to the manufacturer specified settings to prevent loose contacts. Always disconnect power before performing any wiring changes.
