Contact-less direct and alternating
TRMS current transducer
Overall description
The T201DCH is an isolated, contact-less direct and alternating TRMS current transducer.
The device's function and look are very similar to those of an active standard CT, but with
the remarkable feature of measuring the continuous component of the pass-trough
current. For its electrical endurance, ease of use and compact dimensions,the T201DCH
fits every kind of current measurement up to 50 Adc or 50Aac.
Similar usage to a standard alternating current active CT.
HW
No shunt, no wasted power of primary current circuit.
High accuracy rating: class |0.5|.
Suitable for use with all the Seneca modules that supply the T201DCH
with at least 12Vdc and that have a 0-10Vdc analogue input
Two ranges that are dip-switch selectable.
Damping filter availability to improve stable reading.
Suitable for batteries , battery chargers, solar panels, power units and
generic dc loads.
Compact size: overall dimensions equal to

The T201DCH can be located in any position and place, in accordance with the operating
conditions above stated. Use the included holder bracket when fixing to a DIN rail.
WARNING: High-strength static magnetic fields may change the output value: let avoid
closeness to permanent magnets, electromagnets or iron bulks that cause such a modifi-
cation of the surrounding magnetic field; try a different arrangement or orientation if zero-
error was greater than expected.
Multi-turn primary winding to improve sensibility
You can increase the sensibility of T201DCH simply passing several times in the hole with
the measuring current, realizing turns with multiplicative effect: for example, passing 5
times in the hole, as to see 4 turns, choosing a 50 A range, you get an equivalent sensi-
bility of 10 A full-scale. When you make this, let dispose the turns with symmetry in order
to preserve accuracy: use diametric contraposition with 2 turns, cross disposition with 4
turns, with 6 turns as like as 4 + 2, and so on.
Disposal of electrical & electronic equipment (applicable throughout the EU and other countries wit separate collection programs). This symbol, found on your product or on
its packaging, indicates that this product should not be treated as household waste when you wish to dispose of it.Instead,it should be handed over to an applicable collection
point for the recycling of electrical and electronic equipment. By ensuring this product is disposed of correctly, you will help prevent potential negative consequences to the
environment and human health, which could otherwise be caused by inappropriate disposal of it. The recycling of materials will help to conserve natural resources. For more
