PointScan/222
High Density Discrete Input Module
Overview
Sixteen discrete inputs accept DC sourcing signals that are all tied to a common return. More information
can be found in the on-line help supplied with the IO Toolkit.
Number of Channels 16 discrete inputs (connected to a common DC source)
Input Voltage Range 10 - 30 VDC
Input Current @ 12 VDC 3.5 mA
Input Current @ 24 VDC 7.0 mA
Wiring
This high density input module provides a single terminal input for each channel. Positive DC voltage must
be applied to an input to indicate an ON condition. All channels are referenced to a common return which
is connected to the negative side (ground) of the DC power source.
