Occupation of not used inputs
To guarantee the correct operation of the internal test routines not used analog inputs have to
be terminated with resistors.
Not used inputs, single channel connection
All examples are for channel 1
Installation of the resistors outside the cable connectors: On terminals.
Application example 4:
R01, R03, R05, R07 = 50
Ω
R02, R04, R06, R08 = 220 Ω / 0.5 W, 5 %;
part no. 00 0471221
Redundant connection of smart transmitters
Application example 5:
Redundant connection for Zener barrier
Resistor R01 = 50
Ω
Note if used together with zener barrier:
To avoid cross talking in case of a short circuit
between the supply line of a transmitter and the
cable screen earthing of the analog GND of the
module F 6214 is recommended.
