Programmable LED indicator
5714
– 4-digit 14-segment LED display
– Input for mA, V, Ohm, RTD, TC and potentiometer
– 2 relays and analog output
– Universal supply
– Front key programmable
Application
• Display for digital readout of current / voltage / resistance /
temperature or potentiometer signals.
• Process control with 2 potential-free relays and / or analog
output.
• For local readout in extremely wet atmospheres with a
specially designed splash-proof cover.
Applications
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.
• Help texts in eight languages can be selected via a menu
item.
• PR5714 is available fully-configured according to
specifications ready for process control and visualization.
• In versions with relay outputs the user can minimize the
installation test time 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, PR5714 can be
delivered with a specially designed splash-proof cover as
accessory.
