NXC-I/O10 Input/Output Control Card
12 NetLinx Cardframe, Control Cards, and NetModules - Operation Reference Guide
The NXC-I/O10 responds to switch closures or voltage-level (high/low) changes. Compatible I/O devices include the
Power Control Sensor (PCS), tape transports and limit switches. The inputs are set for SW mode (closure) or VO mode
as described below.

NXC-I/O Channel Assignment
Channel Description
1-10 Represent I/O channels 1-10
SW (switch) Mode
setting (default)
(Jumper pins 2 and 3)
Senses switch or relay contact closures or provides a logic-level
output. The 3-pin jumpers for each input should be set to SW before
wiring inputs to the Card. An "On" condition is triggered by contact
closures or a logic low of 0 to 1.5 VDC.
An "Off" condition is triggered by a logic high of 2.5 to 5 VDC; set the
associated I/O to switch mode. When used for an output, each I/O
port acts as a switch to ground (GND), and is rated at 200 mA @ 12
VDC.
VO (voltage) Mode
setting
(Jumper pins 1 and 2)
Senses high- and low-voltage states commonly from AC or DC
signals. This mode provides opto-isolation. The 3-pin jumpers for
each input should be set to VO (voltage mode) before wiring inputs to
the Card.
An "On" condition is triggered by DC levels from 2.5 to 28 VDC (+ or
-), or AC levels from 2.5 to 24 VAC. An "Off" condition is triggered by
DC levels from 0 to 1.5 VDC (+ or -) or AC levels from 0 to 1.5 VAC.
