the OEM6250 PCB
and connect IN-P to an
external supply of up
to 24VDC.

If you wish the outputs
to be pulled up to a

and connect OUT-P to
an external supply of
up to 24VDC.
Inputs
HCMOS-compatible voltage levels
(Low
£
1.00V, High
³
3.25V).
Voltage range = 0-24V.
Sourcing Current: Leave as is to use the
internally su5VDC pull-up supply, or
remove R12 and connect
IN-P
to an external
5-24VDC power supply.
Sinking Current: On the
AUX
connector,
connect
IN-P
to
GND
(remove R12 first).
STATUS: Check with
TIN
or
INFNC
.
Active level: Default is active low, but can
be changed to active high with the
INLVL
command.
Outputs
Open collector output.
Max. voltage in the OFF state (not sinking
current) = 24V; max. current in the ON state
(sinking) = 30mA.
Pull-up connection on
AUX
connector:
Leave as is to use the internally supplied
+5VDC pull-up supply, or remove R13 and
connect
OUT-P
to an external 5-24VDC
power supply.
STATUS: Check with
TOUT
or
OUTFNC
.
Active level: Default is active low, but can
be changed to active high with the
OUTLVL
command.
NOTE: All even-numbered pins are connected to a common digital ground — see drawing on page 5.
LSB = least significant bit; MSB = most significant bit
CAUTION
:
If you fail to remove the resistor (R12 for inputs, or R13 for outputs) before connecting an
external supply to the inputs pull-up terminal (
IN-P
) or the outputs pull-up terminal (
OUT-P
),
you will damage the OEM6250.

NOTE
: You must first
remove the resistor
(R12 for inputs, or R13
for outputs) before you
can connect an external
supply to the inputs
pull-up terminal (IN-P)
or the outputs pull-up
terminal (OUT-P);
otherwise, you will
damage the OEM6250.

(only if the cable is
connected as
illustrated).
