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.

• U e only a crewdriver with appropriate head
Select connection
cable
Preparing cables
Take note the uitability of the connecting cable
(wire cro - ection, in ulation, etc.).
You may u e either olid conductor or flexible conductor.
In ca e of u ing flexible conductor u e crimped wire end.
In ca e of main connection the wire cro - ection hould
be 1.0 mm2 (min.).
In ca e of 5 AAC input current the wire cro - ection hould
be 1.5 mm2 (min.).
In ca e of connection communication cable take note the
concerning pre cription (www.modbu .org).
It’ an important rule that the power cable and ignal
cable hould lead on a eparate way.
Prepare the cable for the connection.
Strip approx. 8 mm in ulation.

connected all the cable , have you connected to the right
place, do not the cable-end touch each other).
Put the instrument
under suppl voltage
Put the instrument under suppl voltage
After you have completed the connection , put the
in trument under upply voltage. If the upply connection i
correct the di play give light.
