3.3. Operating principle
Area of application The DT4220 xx xx xx (PS) Process Indicator enable process variable
0-20 mA, 4-20 mA, 0-10 V, 0-5 V, 2-10 V to be displayed in
engineering units ont he control panel.
Any optional display range can be assigned to the input signal range.
Large 5 digit, 14.2 mm height LED display make process value easily
visible at a distance.
Options:
RL2
Two normally open relay contacts (SPST) for limit switching or for
simple control tasks.
IA / IP
4-20 mA / 0-20 mA galvanic isolated scaleable analogue output. The
output can be active (A) or passive (P).
TS
Galvanic isolated power supply output for 2, 3 or 4 wires transmitter.
RS2
RS232 galvanic isolated communication output with MODBUS RTU
slave protocol. Only one instrument can be connected to the one
RS232 connector of PLC or to the computer.
RS4
RS485 galvanic isolated communication output with MODBUS RTU
slave protocol. 32 instruments can be connected to one RS485
connector of the PLC or to the computer.
Note: only one in five (IA, IP, TS, RS2, RS4) option can be
implemented at the same time. The option RL2 always can be
implemented independently another option.

DT4220 E
820180619-V0
Operating principle The input current or voltage to be measured is led to the 23 bit A/D
converter through a protection and signal condition circuit.
The digital output signal of the A/D converter is processed by a
microcontroller.
The microcontroller drives the 5 digit LED display, processes the front
panel membrane keypad, drives the limit relays, the analogue output
and the communication output.
Easy on-site configuration through the front panel membrane keypad
is a major advantage of the microcontroller-based technology. The
configuration parameters: input signal selection, signal filtering,
display scaling, decimal point position, display refresh rate, limit
modes, limit values, etc. are stored in FRAM. The settings are
protected by a two-level password against unauthorized manipulation.
Power supply The instrument has two power supply version:
DT4220 E xx xx xx: 19-50 VDC / 19-35 VAC 3 W / 3.5 VA
DT4220 E xx xx xx PS: 90-250 V AC/DC 3.5 VA / 3 W

DT4220 E

3.4. Adjustment
The instrument can be adjusted through the
3 button front panel keypad. All configuration parameters are stored in
the instrument FRAM for unlimited time, even when the supply voltage
being switched off.
The instrument doesn't need any internal adjustment.
3.5. Display, indicators
The following figure shows the front panel of the instrument:
1. 5 digit 7 segment LED for displaying the measured value and the
mnemonic messages.
2. "Rel1" yellow indicator for indicating that limit output 1 is in "on-
state" (LIMIT1).
3. "Rel2" yellow indicator for indicating that limit output 2 is in "on-
state" (LIMIT2).
4. "Status" yellow indicator for indicating that a successful data
exchange has granted through the communication output.
3.6. Storage and transport
This instrument should be stored and transport in places whose
climatic conditions are in accordance with Chapter 10.1. Technical
specifications, as described under the title: Environmental
conditions.
The packaging of instrument consist of environment-friendly,
recyclable cardboard is used to protect the instrument against the
impacts of normal stresses occurring during transportation. The
corrugated cardboard box is made from environment-friendly,
recyclable paper. The inner protective material is nylon, which should
be disposed of via specialized recycling companies.

5. Connecting
5.1. Preparing the connection
Always observe the following safety instructions:
•Connect or disconnect only in the complete absence of line voltage
•Take note the data concerning on the
overcurrent protection in installation.
•Use only a screwdriver with appropriate head
Select connecting
cable
Take note the suitability of the connecting cable
(wire cross-section, insulation, etc.).
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
In case of mains connection the wire cross-section should be 1.0 mm2
(min.).
In case of connection communication cables take note the concerning
prescriptions (www.modbus.org).
It's an important rule that the power cables and signal cables should
lead on a separate way.
