Interface card CBT 420 is a serie BLOCK module
capable to solve most of long distance transmission problems of
an analog signal.
The card transforms up to 4 voltage input signals whose
range is selectabe between 0÷5 V or 0÷10
V, into as many current signals. Connection to the field is
performed through quick release screw terminal connectors.
Typical use of this card is current analog signals transmission,
also across remarkable distances, mantaining a great accuracy
for the information transmitted. Current transmission has the
advantage that it is not influenced by distance and environmental
noise.
Using card RCV 420 is very comfortable to approach this
kind of problems because it warrants 14 bit of accuracy
for the conversion Voltage-Current.
Five status LEDs inform about the module working conditions,
allowing to decide its optimal situation with one look only.
