PR Electronics 9107A HART Transparent Driver is a versatile 1- or 2-channel isolated driver designed for the operation and control of I/P converters, valves, and indicators. It supports bi-directional HART communication, making it suitable for controlling HART devices. This driver can be mounted in safe areas or hazardous zones, providing reliable signal control and monitoring capabilities.

Applications

  • Isolated Signal Driving: Provides isolated 1:1 driving for operation and control of I/P converters, valves, and indicators.
  • HART Device Operation: Supports bi-directional HART communication for controlling HART devices.
  • Signal Splitting: Dual channel versions can be used for signal splitting applications, allowing 1 input to be split into 2 outputs.
  • Loop Current Monitoring: The PR 45xx displays process values and can define high and low limits for loop current detection, activating the status relay if limits are exceeded.

Advanced Features

  • Operational Status Indication: The PR 45xx detachable display and green and red front LEDs indicate the operation status for each channel.
  • Tag Number Assignment: Allows for the definition of a tag number for each channel for easy identification.
  • Fault Detection: Provides output line fault detection for enhanced reliability.
  • Limit Switch Functionality: In the 1-channel version, the status relay can be used as a simple limit switch.
  • Performance Level Compliance: Suitable for use in systems up to Performance Level “d” according to ISO-13849.

Technical Characteristics

  • High Galvanic Isolation: Provides high galvanic isolation of 2.6 kVAC, ensuring robust signal separation.
  • High Accuracy: Delivers high accuracy better than 0.1%, ensuring precise signal control.
  • Data Safety: Continuously checks vital stored data for safety reasons, ensuring reliable operation.

Mounting

  • Flexible Mounting: Can be mounted vertically or horizontally without distance between neighboring units, allowing for efficient use of space and high channel density.

PR Electronics 9107A HART Transparent Driver is an ideal solution for industries requiring reliable signal driving, HART device control, and advanced monitoring features, particularly in environments with stringent safety and performance requirements.
