Note
This figure shows a serial port connection. USB connections are also supported.
The signal converter must be connected across a resistance of
250–600
Ω
. The mA
output requires an external power supply with a minimum of
250
Ω
and 17.5 V. See
the following figure to help determine the appropriate combination of voltage and
resistance. Note that many PLCs have a built-in
250-
Ω
resistor. If the PLC is powering
the circuit, be sure to take this into consideration.
