3.3 Input and Output Specifications
3.3.1 General-Purpose Inputs
The I/O Expansion Module extends the capabilities of supported In-Sight vision sensors by
providing eight independent, general-purpose inputs that can be used to trigger event execution
on the sensor. LED indicators are provided on the I/O Expansion Module to indicate the state of
the inputs.
NOTE The general-purpose I/O signals are approximately 1ms slower in updating and are inverse in polarity when
compared to the high-speed outputs. This delay must be considered when trigger rates are faster than the
required processing time.

SPECIFICATION DESCRIPTION
ON 20 to 28V (24V nominal) VOLTAGE
OFF 0 to 1.5V (10V nominal threshold)
ON 1mA to 1.3mA
OFF <50 µ A
CURRENT
Resistance ~22 K Ohms
DELAY 600 µ Sec max. between change of input state and completion of serial transmission to the
In-Sight sensor.
CAUTION The In-Sight 1450 I/O Expansion 24V OUT pins are intended to supply low current in
support of the I/O lines. Do not use these pins to supply power to other devices.
