LooP-PoWERED LCD INDICAToR 5531
• 4-digit LCD display 48 x 96 mm
• Loop-powered
• Easy scalable from front keys
• Backlight
• Standard and ATEX Ex version
• IP65 enclosure from front
APPLICATIoN:
The PReview 5531 indicator is ideal for local readout of 4...20 mA current
signals scaled directly in process units. PReview does not need any external
power supply as the indicator is powered by the 4...20 mA loop signal.
The Ex version 5531B can be used in hazardous areas classified as zone 1 or 2.
5531B1 includes an Ex field enclosure suitable for use in zones 2 and 22
without the need for a barrier. 5531B2 includes an Ex field enclosure for use in
zones 1, 2, 21, or 22.
TEChNICAL ChARACTERISTICS:
Input: 4...20 mA standard signal.
An adhesive label with process units may be attached to the front below the
digits.
Input voltage drop is
≤
1.5 VDC, corresponding to a feed-through resistance of
75
Ω
(when backlight is switched off). Reversed display readout is possible, see
routing diagram.
PRogRAMMINg / SCALINg:
Dipswitch 1, switch 1 on the rear panel is used to enable / disable the front
keys thus facilitating scaling.
Scale mode: In scale mode the indicator may be scaled, see routing diagram.
Run mode: In run mode the indicator will display the actual current according
to the scaling.
Backlight: Dipswitch 1, switch 2 and 3 on the rear panel is used to select
backlight intensity, see programming. Please note that the input voltage drop is
dependent on backlight intensity.
