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.

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.
• PR 5714 is available fully-configured according to specifications ready for process control and visualization.
• 2.3 kVAC galvanic isolation between input, output and supply.
• 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.
