1.1.

 

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 

BE REPRODUCED WITHOUT PRIOR PERMISSION.
