3.3. Principle of operation
Area of application The DT1600 Ux xx xx AC Voltage Transmitters provide an
output signal proportionally with the average value (F) or
with the TRMS value (R) of the input AC voltage.
The version marked with R is recommended to use for
measure of non-sinusoidal signals.
The output can be current (0-20 mA, 4-20 mA), active (A) or
passive (P) or voltage (0-10 V).
In all types the input, the output and power supply are
galvanic isolated from each other.
Operating principle
The AC voltage connected to the input is transformed and
isolated by the input transformer. The secondary voltage of
the transformer is lead to the AC/DC converter. The DC
voltage controls the output current or voltage according to
the input AC current.

5. Connecting
5.1. Preparing the connection
Select connection
cable
Preparing cables
Always observe the following safety instructions:
• Connect or disconnect only in the complete absence of
line voltage
• If overvoltages are accepted, overvoltage arresters
should be installed
• You should take note the data concerning on the
overcurrent protection in installation.
• Use only a screwdriver with appropriate head
Take note the suitability of the connecting cable
(wire cross-section, insulation, etc.).
You may use either solid conductor or flexible conductor.
Prepare the cable for the connection.
Strip approx. 8 mm insulation.
In case of using flexible conductor use crimped wire end.

The following figure shows the wiring plan, connecting the
transmitter:
Wiring plan, connecting
to the power network
(see also “Application
example”)
1. Loosen terminal screws.
2. Insert the wire ends into the open terminals according to
the wiring plan.
3. Screw the terminal in.
4. Check the hold of the wires in terminals by pulling on
them firmly.

6. Fault rectification
6.1. Fault finding
The fault finding must be carried out by trained and
authorized personnel only.
•The green indicator is dark →check the mains voltage.
If the mains voltage is OK: the instrument is defective.
•There is no output signal →check the input signal.
If the input signal is OK: the instrument is defective.
When the result of fault finding is that the instrument is
defective call the manufacturer service department.

8. Calculation for application
8.1. Calculations
Calculating the input voltage from the transmitter output
signal.
UX[V]: voltage to be measured
n: voltage transformer ratio
(in case of direct connection n = 1)
UIN [V]: transmitter input voltage
IOUT [mA], UOUT [V]: transmitter output signal
In case of I0, U10 outputs:
UX= n * UIN * IOUT / 20 UX= n * UIN * UOUT / 10
1st example:
IIN = 250 V IOUT = 18 mA n = 10
IX= 10 * 250 * 18 / 20 = 2250 V
In case of I4 output:
UX= n * UIN * (IOUT - 4) / 16
2nd example:
IIN = 250 V IOUT = 12 mA n = 10
IX= 10 * 250 * (12-4) / 16 = 1250 V
