Description
The T201DCH50/100/300-M are isolated, contact less loop powered AC/DC current transducers. The look and
device’s function are very similar to those of an active standard Current Transformer, but with the remarkable
feature of measuring the DC and AC component. For its electrical endurance, ease of use and compact
dimensions, the T201DCH50-M, T201DCH100-M and T201DCH300-M fit every kind of current measurement:
up to 50 Adc/Aac, 100 Adc/Aac and 300 Adc/Aac (respectively).
A RS485 port with a standard Modus RTU protocol is also available.
The device can measure a current in 2 different modes (using dip switches or the Easy Setup Software):
TRUE RMS AC/DC CURRENT MEASURE
DC BIPOLAR CURRENT MEASURE (used also for obtain the sign +/- of a DC current)
1.2.
Features
Similar usage to a standard alternating current active C.T.
No shunt, no wasted power from the measure circuit
High accuracy rating (>2% FS): 0.3% for 50A and 100A models / 0.5% for 300A model.
Suitable for use with all Seneca modules that allow to power the device with at least 12 Vdc and having a
0 – 10Vdc input
Simple configurable with dip switches or with the free Easy Setup software
Two ranges, dip-switch selectable
Damping filter availability to improve stable reading
Modbus RTU protocol by RS485 port
Modbus Address/Baud Rate/Range/Mode configurable also from dip switch
