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 0, 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 feedthrough resistance of 75 Ω (when backlight is switched off).
Reversed display readout is possible, see routing diagram
on the reverse.
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 on the reverse of this data sheet.
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 on the
reverse of this data sheet. Please note that the input voltage
drop is dependent on backlight intensity.
Field enclosure type 8501:
The field enclosure type 8501 complies with industrial standards for efficient protection of process equipment in wet
areas up to IP65. When 8501 is delivered with a built-in
PReview 5531, the assembled unit is approved for installation in explosive gas atmospheres as well as in explosive
dust environments. The technical specifications of the field
enclosure can be found in the 8501 data sheet.
