The discrete inputs and outputs are compatible with 12-24 Volt systems and are polarity independent for
compatibility with virtually any PLC. Inputs and outputs are not individually isolated but have separate
common pins and are fully isolated from the power input as well as the CS24D internal circuitry and
RS232 port. The power input accepts 12-24Vdc and is isolated from other pins. (The RS232 port is not
isolated from the internal circuitry and is not intended to be connected during regular use of the sensor).
The CS24D has five indicator LEDs. The blue Run LED indicates that the unit is on and flashes when in
Teach mode. The four green Output LEDs indicate which outputs are on (which color is detected) during
run mode and flash to indicate which output is being taught in Teach mode (actual outputs remain off
when in Teach mode).
The CS24D contains high intensity LEDs in multiple wavelengths to illuminate the object to be sensed,
and a precision silicon photodiode to read the diffuse reflected light from the object—no additional
lighting is required for operation. The CS24D reads the average color within the sensing area. The
CS24D’s lighting system is much more intense than it appears because of the low duty cycle of its light
emitting diodes (LEDs). The CS24D is not affected by normal room lighting, however very strong light
(e.g. sunlight) should be kept out of the sensing area and light should not be allowed to shine directly into
the sensor.
The high-intensity LEDs in the CS24D’s lighting system have a typical life of 50,000 hours. The
intensity of all LEDs varies with temperature and time due to the properties of the semiconductor
materials used. The CS24D compensates for both types of variations greatly reducing the need for
periodic teaching.
