General

The COLORLINE-1728 image recorder consists of a CCD color line scanning camera which is distinguished by outstanding sensitivity, linearity and color stability. The color pixels in the utilized sensor chip are not arranged in three staggered, side-by-side sensor lines, but rather in a single line with a pixel sequence of R(ed), G(reen), B(lue) resulting in the following line configuration: RGBRGBR etc. As opposed to three-line technology, this single line array is often advantageous in industrial applications. The object to be scanned is seldom moved at a constant speed. This means that color line scanning cameras which utilize three sensor lines (RGB) arranged one next to the other require external synchronization logic in order to match up the lines. In the event of irregular speeds, this problem is quite difficult, or impossible to solve (e.g. sorting free-falling objects).

Process trigger signals can be directly connected to the COLORLINE-1728, for example from an incremental encoder used to indicate the beginning of the line, or a frame start initiator. These devices are supplied with suitable electrical power directly from the camera. This results in extremely simplified system wiring because, as a rule, all of the components are installed at the production line anyway. The camera is furnished with a single-supply 12 V mains power pack, because all required operating voltages can be generated by means of a DC-DC converter inside the camera. Some frame grabbers provide 12 V DC auxiliary power at the computer side via their interface plugs. In this way, supply power can also be fed to the camera via the data / interface cable. If the frame grabber is not equipped with auxiliary power, the 4-pin power socket at the back of the camera is used.

Special Features

• Single line pixel array: RGBRGBR ...
• Watchdog in the camera:
  If the production line comes to a standstill, the camera continues to run on its own at 38 Hz.
  Valid lines are transmitted once again, immediately after production is resumed.
• Trigger sources for line and image import can be connected directly to the camera,
  and power is supplied from the camera.
• Adjustable exposure time in free-running and encoder controlled operating modes
• Adjustable prescaler for line trigger signals from the incremental encoder
• Camera can be operated in free-running mode
• Single operating voltage: +12 V DC
• Internal or external master clock
• Exposure time control
• Highly sensitive:
  R 3.7, G 5.5, B 2.2 V / (lx*s)
• Gain can be programmed with control bits
• All trigger and control functions are implemented via the frame grabber.
