2.0 DESCRIPTION AND GENERAL SPECIFICATIONS
2.1 Description
The T201DC100 is an isolated and passive, contact-less loop powered direct current
transducer. The T201DC100 has functions and look very similar to a standard current
transformer, but it is enabled to measuring the continuous current component that flowing
through it. For its electrical endurance, ease of use and compact dimensions, the
T201DC100 fits every kind of current measurement up to 100 Adc.
2.2 General specifications
- Suitable for solar panels, batteries, battery charger,power units and generic DC load.
- No shunt, no power consumption from the measure circuit
- High accuracy rating: class |0.2|
- Loop-powered 4 – 20 mA, 6 to 28 V, protected from reverse polarity and
transient up to 120 V, surge up to 1.5 J.
- Eight scales unipolar or bipolar selectable via dip switches
- Damping filter available to improve the stability of reading
- Reading of current pulsed or alternating currents with superimposed components
- Built-in microprocessor system fault check
- Over-temperature protection
- "single wire" possible wiring by powering with the device from the measuring current itself
and closing to the system common return.
- Possibility of mounting on the DIN rail through the support provided in the sales package.

5.0 ELECTRICAL CONNECTIONS
Remove power supply before wiring.
5.1 Output current loop 4 – 20 mA
A maximum voltage supply of 28 V
can be connected directly to the loop
4 – 20 mA of the T201DC100.
3.7 Standards
Standards
EN61000-6-4 (electromagnetic emission, industry).
EN64000-6-2 (electromagnetic immunity, industry).
EN61010-1 (safety).
Notes:
- Use with copper conductor.
- Use in Pollution Degree 2 Environment
- Power Supply must be Class 2
4.0 PRELIMINARY INSTRUCTION FOR USE
The T201DC100 can be installed in any position and place in accordance to expected
environmental conditions. Use the included holder bracket when fixing to a DIN rail.
High-strength static magnetic fields may change the output value: keep away from
permanent magnets, electromagnets or iron bulks that cause such a modification
of the surrounding magnetic field; try a different orientation if zero error was greater
than expected.

5.2 Connection for reading input current
To measure the current flowing through the cable,
plug the cable into the center hole of T201DC100
(as shown in the figure).
The maximum current that can be measured using
T201DC100 is 100A.
To increase the sensitivity of current measurement,
insert the wire several times through the center
hole T201DC100, creating a series of turns. The
sensitivity of current measurement is proportional
to the number of turns. Example:
Choose the end scale and wrap the wire 5 times
around the center hole obtaining 4 turns. The initial
end scale will be result 5 times smaller: the
measure proves to be more sensitive
Place the coils with symmetry in order to maintain
the sensitivity of the device.
The current direction is
shown in the figure above.
