KFD2-STC4-Ex1
- Input 0/4 mA ... 20 mA Output 0/4 mA ... 20 mA General specifications Signal type Analog input Supply Connection Power Rail or terminals 14+, 15- Rated voltage 20 ... 35 V DC Ripple within the supply tolerance Power loss 1.4 W
SMART transmitter power supplies
provide a 2- or 3-wire SMART
transmitter and transfer the analogue
values.
Digital signals may be superimposed on
the analogue values, which will
transferred bidirectionally. Handheld
terminals should be connected as
shown in the block diagram.
An internal resistor at terminal 9 is
available, which may be used to
increase the AC impedance for the
HART signal.
SMART transmitter power supplies are
delivered with terminal type KF-STP-**.
Jacks are integrated in these terminals
or the connection of the handheldunits.
