Contact Connection
Be sure to observe polarity when connecting current output devices
to these terminals.
•
Using the contact input, there are two methods to connect a switch contact to
the I/O ports:
-
using the internal power supply
-
using an external power supply
The internal isolated power supply terminals are VDC Output +
and VDC Output -. The voltage is 24 VDC and the current rating is
± 42 mA.
NOTE
•
Connection using Internal Power Supply
Using the internal power supply (+VID), connect one side of the switch to
VDC Output + and the other side of the switch to Contact Closure + (See the
following figure).
If using an external power supply, the maximum input voltage
between Contact Closure + and VDC Output - is 24 volts.
•
Connection using External Power Supply
Using an external power supply, connect the negative (-) terminal of the
power supply to VDC Output -. Connect one side of the switch to the
positive (+) terminal of the power supply, and the other side of the switch to
Contact Closure + (See following figure).
