8.6 Digital Inputs
NOTE: Refer to the datasheet for XL+ OCS model being used for details on jumper settings.
NOTE: The digital inputs on the XL+ OCS are designed for low voltage DC inputs
.
The inputs are
designed to support both positive and negative input modes. The mode is set by a jumper setting
and a configuration parameter in Cscape. All the inputs on the unit must be configured to the
same mode.

Positive and Negative Inputs
In positive logic mode, a positive voltage applied to the input will turn the input. The internal
design of this mode is basically a resistor from the input to I/O ground. This mode is sometimes
called sourcing.
In negative logic mode, connecting the input to the I/O ground or zero volts will turn the input
on. The internal design of this mode is basically a resistor from the input to the positive I/O
voltage (usually 12V or 24V). This mode is sometimes called sinking.
Some of the digital inputs may support high-speed input functional such as counting or
frequency measurement.
