PROGRAMMABLE LED INDICATOR
MAR NE
4-digit 14 segment LED indicator
Input for mA, V, Pt100, TC and Potm.
2 Relays and analogue output
Universal voltage supply
Front key programmable
Application:
• Display for digital readout of current, voltage,
temperature or 3-wire potentiometer signals.
• Process control with 2 potential free relays
and / or analogue output.
• For local readout in extreme wet atmospheres
with a special designed splash-proof cover.
Technical characteristics:
• 4-digit LED indicator with 13,8 mm 14 segment characters. Max. display readout 1999...9999 with programmable decimal point,
relay ON / OFF-indication.
• All operational parameters can be adjusted to
any application by use of the front keys.
• PReview 5714 is available fully-configured
according to specifications ready for process
control and visualisation.
• In versions with relay outputs the user can
minimise the installation test time by activating
/ deactivating each relay independent of the
input signal.
Mounting:
• To be mounted in front panel. An included
rubber packing must be mounted between
the panel cutout hole and the display front
to obtain IP65 (NEMA 4) tightness. PReview
5714 can be delivered with a special designed
splash-proof cover as accessory to obtain
IP67 tightness.
