Application

  • Display for digital readout of current / voltage / resistance / temperature or 3-wire potentiometer signals.
  • Process control with 4 pairs of potential-free change-over relays and analog output.
  • For tank level control, with the possibility of customer linearization ensuring correct level measurement and control in non-linear tanks.

Technical characteristics

  • 4-digit LED indicator with 13.8 mm 14-segment characters. Max. display readout -1999…9999 with programmable decimal point and relay ON / OFF indication.
  • All standard operational parameters can be adjusted to any application by way of the front function keys. When programming is carried out by way of a PC and the configuration program PReset, additional configuration options are available, such as customer-defined linearization and special input signals.
  • Help texts in eight languages can be selected via a menu item.
  • A menu item allows the user to minimize the installation test time for the relay outputs by activating / deactivating each relay independently of the input signal.

Mounting / installation

  • To be mounted in panel front. The included rubber packing must be mounted between the panel cutout hole and the display front to obtain a protection degree of IP65 (type 4X). For extra protection in extreme environments, PR5715 can be delivered with a specially designed splash-proof cover as accessory.
