3.3. Principle of operation
Area of application The DT4260 xx xx xx xx AC Current Meter enable
0-1 AAC / 0-5 AAC current range to be di played on the
control panel. Large 14.2 mm height LED di play make
proce value ea ily vi ible at a di tance. The di played
value i proportional to the True RMS value of the input
current.
The input current to be mea ured hould be connected to
the in trument’ input hunt through a current tran former.
Ea y on- ite configuration through the front panel
membrane keypad i a major advantage of the
microcontroller-ba ed technology. The configuration
parameter : input range, current tran former ratio, ignal
filtering, output caling, di play refre h rate, limit mode ,
limit value , etc. are tored in EEPROM. The etting are
protected by a two-level pa word again t unauthorized
manipulation.
Option :
• Two normally open relay contact (SPST) for limit
witching or for imple control ta k .
• 4-20 mA / 0-20 mA galvanic i olated calable analogue
output. The output can be active (A) or pa ive (P).
• RS232 galvanic i olated communication output with
MODBUS RTU lave protocol. Only one in trument can be
connected to the PLC or to the computer.
• RS485 galvanic i olated communication output with
MODBUS RTU lave protocol. 32 in trument can be
connected to the PLC or to the computer.
Note: either analogue or communication option can be
implemented at the ame time.

Operating principle The mea uring current flow through the input hunt
re i tor. The voltage drop on the hunt re i tor i lead to the
ignal conditioner and TRMS / DC converter tage. The DC
voltage output of thi tage i converted by a 21 bit A/D
converter into digital value. The digital value i proce ed
by a microcontroller. The microcontroller drive the 5 digit
LED di play, proce e the front panel membrane keypad,
drive the limit relay , the analogue output and the
communication output.
Power suppl The in trument ha two power upply ver ion:
DT4260 xx xx xx: 18-40 V AC/DC 3VA / 3.5 W
DT4260 xx xx xx PS: 180-250 V AC/DC 3VA / 3.5 W
3.4. Adjustment
The DT4260 xx xx xx xxcan be adju ted through the 3
button front panel keypad. All configuration parameter are
tored in the in trument EEPROM for unlimited period of
time, even when the upply voltage beeng witched off.
The in trument doe n’t need any internal adju tment.

3.5. Displa , indicators
The following figure how the front panel of the in trument:
1. 5 digit LED di play di playing the mea ured value and
the mnemonic me age .
2. „Rel1” yellow indicator for indicating that limit output 1 i
in “on- tate” (LIMIT1).
3. „Rel2” yellow indicator for indicating that limit output 2 i
in “on- tate” (LIMIT2).
4. „Status” yellow indicator for indicating that a ucce full
data exchange ha granted through the communication
output.
3.6. Storage and transport
Thi in trument hould be tored and tran port in place
who e climatic condition are in accordance with Chapter
10.1. Technical specifications, a de cribed under the
title: Environmental condition .
The packaging of DT4260 xx xx xx xx con i t of enviroment-
friendly, recyclable cardboard i u ed to protect the
in trument again t the impact of normal tre e occurring
during tran portation. The corrugated cardboard box i
made from environment-friendly, recyclable paper. The
inner protective material i nylon, which hould be di po ed
of via peciali ed recycling companie .

4. Mounting
4.1. General instructions
U e the enclo ed eal between the in trument and the
panel when mounting the in trument to a ure IP 65 from
the front.
Mounting positions Select a mounting po ition you can ea ily read the di play
reach for mounting and connecting the in trument and that
minimi e the hazard of water, du t or dump getting into the
in trument.
