4. Interface and Wiring
The CS24D discrete inputs and outputs are compatible with 12-24 Volt systems and are polarity
independent for compatibility with virtually any PLC.
Four (4) discrete outputs convey the sensing results. These results are binary coded which allows for
sixteen conditions—fifteen Sort Outputs plus a No Match output (all outputs off).
These solid state relay (SSR) outputs are optically isolated from all other circuitry. They are polarity
independent and share a common pin, so all four outputs must be the same polarity (high side or low
side switching).
The CS24D also has four (4) discrete inputs. Three of the inputs are used to Teach the sensor
(Teaching can also be done using the ColorSense program), and the fourth input is used to synchronize
the output data. See Options sections for more information on synchronization.
These opto-coupler inputs are isolated from all other circuitry. They are polarity independent and share
a common pin, so all four inputs must be the same polarity (sink or source inputs).
