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.
