E1702S Slim XY2-100/XY3-100/NX-02 Scanner Controller

Beside different other, common scanner cards BeamConstruct also supports the E1702S scanner controller card which integrates many different functions on a very small space. So this is a low-cost scanner card with the smallest ground-size out there* and similar to the E1701-series it can be extended by additional boards* providing different signals and outputs. Comparing to the E1701D scanner card, the E1702S provides more and other features and functionalities already on the baseboard:

The E1702S is a 2D XY2/100, XY3/100 and NX-02digital scanner controller card which can be extended by options described below. The baseboard provides the following extensive features:

  • 16 (18) bit XY2-100(-E) interface to scanhead with X and Y
  • 20 bit XY3-100 (certified LIA202002 standard) interface with X and Y channel
  • 20 bit NX-02 interface with X and Y channel
  • 100 Mbit Ethernet connection
  • USB 2.0 connection
  • High-definition online XY grid correction with BeamConstruct HD correction files (.bco)
  • Online XY grid correction with support for several correction table file formats (like SCAPS™ .ucf, Scanlab™ .ctb and .ct5, Raylase™ .gcd, Rofin™ .fcr, GSI/CTI™ .xml, Sunny™ .txt, Han's Laser™ .crt)
  • Switching between up to 16 grid correction tables during marking process
  • 10 microseconds vector cycle time and resolution (microstep period)
  • Command execution time down to 0,5 microseconds
  • Realtime processing of laser and scanner signals
  • 26 bit internal resolution (for better quality also with lower resolution hardware output)
  • Can control nearly every laser type (such as CO2, YAG, MOPA,...)
  • LP8 8 bit CMOS level parallel digital output e.g. for controlling laser power
  • LP8 latch and Main Oscillator CMOS level digital output for usage with IPG™, Raycus™ and compatible fiber laser types
  • Pilot CMOS level digital output for use as preview laser control signal
  • Two laser CMOS level digital outputs for usage with YAG, CO2, IPG™ and compatible laser types (outputs provide PWM frequency, Q-Switch, FPK-pulse, continuously running frequency, stand-by frequency), running with frequencies up to 20 MHz
  • 512 MByte DDR3 RAM, Triple-Core CPU wih 1 GHz main CPU clock
  • Support for Micro-SD and Micro-SDHC cards for stand-alone operations
  • Board directly accepts 9..30V power supply
  • Extremely low power consumption of about 1,8 W (Baseboard without any Extension Boards)
  • Internal command and vector data list with more than 17 million entries
  • Continuous list concept, no need to swap between lists
  • BeamConstruct PRO license included
  • Very small size of about 87 mm x 55 mm
  • Hardware/firmware is quality made in Germany

Digi I/O Extension Board requires a baseboard as described above
and provides additional I/Os for controlling external equipment. It offers
following features and functions:

  • 8 digital inputs and 8 digital outputs can be switched to opto-insulated mode with external power supply of up to 24 V
  • 2 inputs can be used for 90 degree phase-shifted encoder signal for marking on-the-fly applications
  • Inputs can be used to select one of up to 256 stand-alone marking jobs stored on microSD card of baseboard

Secondary Head Extension Board gives possibility to connect an additional scanhead which then works fully parallel to the primary one connected to the baseboard and makes use of the same laser:

  • XY2-100/XY3-100 interface for an additional scanhead marking parallel to head of baseboard
  • Up to three of these extensions can be used with one E1702S baseboard to connect a total of up to four scanheads

The optional E170Xbase Mounting Kit allows faster and easier mechanical installation of all types of E1701/E1702 controller boards:

  • Comes with DIN rail / C45 clamps which can be installed in 2 different positions combined with 2 different orientations resulting in 4 different mounting variants
  • E1702S can be mounted on top of E170Xbase with distance bolts or hex-stands using premanufactured mounting holes
  • Can be used also without DIN rail / C45 clamps for custom mounting in machines and as top-cover for E1702S

* As per 02/2023 we do not know of any competitor providing a scanner controller card that is fully modular and comes with a smaller size for such a low price.
