Pepperl+Fuchs KFD2-CR-EX1.20300 071837 transmitter supply isolator 0/4 mA 20mA

Pepperl+Fuchs KFD2-CR-EX1.20300 transmitter supply isolator.

The devices of the KFD2-CR-Ex1.203- series are suited for the connection of 2- and 3-wire transmitters. They may also be used as repeaters for 4 mA ... 20 mA signals (current source). For a supply voltage that is > DC 20 V, the open circuit voltage at the terminals is DC 18 V and is greater than DC 16.5 V with a current of 20 mA.

2-wire transmitters are connected to terminals 1 and 3. The input for the signal current is terminal 3. The minimum available voltage is 12 V at 20 mA.

The power is supplied to terminals 1+ and 2- for a 3-wire transmitter. With a 25 mA supply current, the voltage between the terminals is about 16 V.

Power supplies, whose currents do not have to be transferred to the hazardous area, are connected to terminals 2 and 3. Terminal 1+ remains free and the sources are not supplied with power.
