Connection to a Combination of Sinking & Sourcing Inputs

Combinations of sourcing
and sinking inputs can be
accommodated at the same
voltage level. Be aware of
the input impedance of the
sourcing input module, and
make sure that there is
enough current flowing
through the input module
while in parallel with the
OUT-P pull-up resistor.

Use an external diode when driving
inductive loads. Connect the diode in
parallel to the inductive load,
attaching the anode to the OEM6250
output and the cathode to the supply
voltage of the inductive load, via an
external resistor. To size the external
resistor, use this formula:

PROGRAMMING TIP

Connecting to an active-
high sinking input?
Set
the output’s active level to
high with the

OUTLVL

command

(

1

= active high).

Connecting to an active-
low sourcing input?
Set
the output’s active level to low
with the

OUTLVL

command

(

¯

= active low).

Thus, when the OEM6250’s
output is activated, current will
flow through the attached
input and the

TOUT

status

command will report a “

1

(indicates that the output is
active), regardless of the type
of input that is connected.

Details on setting the active
level and checking the output
status are provided in the
6000 Series Programmer’s
Guide. Refer also to the

OUTLVL

and

TOUT

command

descriptions in the

6000

Series Software Reference.
