Category:

PR Electronics 5714 Programmable LED Indicator is designed for digital readout of various signals, including current, voltage, resistance, temperature, and potentiometer signals. It offers robust process control capabilities with two potential-free relays and an optional analog output, making it suitable for local readout in extremely wet atmospheres with an optional splash-proof cover.

Applications

  • Digital Signal Display: Provides digital readout for current, voltage, resistance, temperature, and potentiometer signals.
  • Process Control: Equipped with two potential-free relays and/or an analog output for advanced process control.
  • Wet Environments: Ideal for local readout in extremely wet atmospheres when used with the specially designed splash-proof cover.

Technical Characteristics

  • 4-Digit LED Display: Features a 4-digit LED indicator with 13.8 mm 14-segment characters. Maximum display readout ranges from -1999 to 9999, with a programmable decimal point and relay ON/OFF indication.
  • Customizable Parameters: All standard operational parameters can be adjusted via the front function keys to suit any application.
  • Multilingual Help Texts: Help texts are available in eight languages, selectable via a menu item.
  • Fully Configured Options: Available fully-configured according to specifications for immediate process control and visualization.
  • Galvanic Isolation: Inputs, outputs, and supply are floating and galvanically separated, ensuring robust isolation and signal integrity.
  • Relay Output Testing: In versions with relay outputs, installation test time can be minimized by independently activating/deactivating each relay regardless of the input signal.

Mounting / Installation

  • Panel Mounting: Designed for mounting in the panel front. The included rubber packing must be installed between the panel cutout hole and the display front to achieve IP65 (type 4X) protection.
  • Splash-Proof Cover: For extra protection in extreme environments, the PR5714 can be delivered with an optional specially designed splash-proof cover.

PR Electronics 5714 Programmable LED Indicator is an excellent choice for industries requiring precise digital readout and advanced process control capabilities, particularly in challenging environments. Its robust design, customizable parameters, and reliable performance make it suitable for a wide range of applications.
