Antwort

The FL1500 has two different ways to wire a device to the 4-20 mA outputs.  The first was is the traditional configuration where the FL1500 powers the 4-20 mA outputs.  For this configuration we use the OUT PWR and OUT LO as shown below ignoring the OUT HI:

Do not connect to a device that has applied voltage.
Do not use the analog outputs to supply power to a 2-wire (loop-powered) transmitter.



The second option is for when a device is connected to a external power supply that is supplying power to the entire loop.  For this configuration we use OUT LO and OUT HIGH shown below and ignore OUT PWR:
