Inputs
Outputs (including OUT-A)
Inputs
HCMOS-compatible voltage levels
(low
≤
1.00V, high
≥
3.25V).
Voltage range = 0-24V.
Sourcing Current: On the
I/O
connector,
connect
IN-P
to
+5V
or connect
IN-P
to an
external 5-24VDC power supply (but not
to both).
Sinking Current: On the
I/O
connector,
connect
IN-P
to
GND
.
STATUS: Check with
TIN
or
INFNC
.
Active level: Default is active low, but
can be changed to active high with the
INLVL
command.
Outputs (including OUT-A)
Open collector output.
Pull-up connection on
I/O
connector:
Connect
OUT-P
to
+5V
, or to an external
5-24VDC power supply (but not to both).
Outputs will sink up to 300mA or source
up to 5mA at 5-24VDC.
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 logic ground (DC ground) — see drawing on page 11.
LSB = least significant bit; MSB = most significant bit
CAUTION
:
You must select either the on-board
+5V
terminal or an external power supply to power the
IN-P
and
OUT-P
pull-up resistors. Connecting
IN-P
or
OUT-P
to the
+5V
terminal and an
external supply will damage the ZETA6xxx.
(The same rule applies to the AUX-P terminal.)
