Programmable LED indicator

5715

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.

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.

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.
