PR Electronics 5715 Programmable LED Indicator is a versatile and user-friendly device designed for digital readout of various signals, including current, voltage, resistance, temperature, and 3-wire potentiometer signals. It offers advanced process control capabilities, making it ideal for applications requiring precise measurement and control.

Applications

  • Digital Readout: Displays current, voltage, resistance, temperature, and 3-wire potentiometer signals.
  • Process Control: Equipped with 4 pairs of potential-free change-over relays and an analog output for advanced process control.
  • Tank Level Control: Suitable for tank level control with customer linearization to ensure accurate level measurement in non-linear tanks.

Technical Characteristics

  • 4-Digit LED Display: Features a 4-digit LED indicator with 13.8 mm 14-segment characters, capable of displaying values from -1999 to 9999 with a programmable decimal point and relay ON/OFF indication.
  • Front Function Keys: Allows adjustment of all standard operational parameters to fit any application using the front function keys.
  • PC Programming: When programmed via PC and the PReset configuration program, additional options such as customer-defined linearization and special input signals are available.
  • Multilingual Help Texts: Help texts available in eight languages, selectable via a menu item.
  • Relay Output Testing: Includes a menu item to minimize installation test time by allowing independent activation/deactivation of each relay regardless of the input signal.

Mounting / Installation

  • Panel Mounting: Designed to be mounted in the panel front with an included rubber packing to ensure IP65 protection (type 4X) between the panel cutout hole and the display front.
  • Extreme Environment Protection: An optional specially designed splash-proof cover is available as an accessory for extra protection in extreme environments.

PR Electronics 5715 Programmable LED Indicator is an ideal solution for industries requiring precise digital readout and advanced process control capabilities, particularly in applications such as tank level control where accurate measurement and control are critical. Its versatile programming options and robust design make it suitable for a wide range of industrial environments.
