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.
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.
