CONNECTION OF THE CT24

Connection for voltage output
When a voltage signal is needed directly from the CT 24,
the conversion from current to voltage can be made
inside the CT 24. For this purpose a precision 500 Ohm
resistor is supplied that can be connected through the
connection strip. This requires however four wires. The
wires used to supply the current and the wires that carry
the voltage output can not be combined. Even though the
return from the current loop and the low of the voltage
output are connected to the same level, the voltage drop
over the cable makes it necessary to use separate wires
for the voltage output.
