  • Pendant/Handwheel HR-20 Open or Close

    The HR-20 handwheel is equipped with a replaceable 3 m cable and USB plug. With the new, more ergonomic housing, the HR-20 fits even better in the hand and can be perfectly stowed away on the CNC machine with the retaining bracket. The axes are conveniently controlled on the HR-20 via a rotary switch. The handwheel is automatically integrated by Windows and only needs to be activated in the WinPC-NC parameters under Basic Settings-interface. Start today and experience a new dimension of machine operation with WinPC-NC and the HR-20 handwheel.

  • PWM-5V/10V Board Open or Close

    The PWM-5V/10V board has been conceived for converting a 5V-PWM signal into an analog 0-5V or 0-10V signal. This signal is made linearly. For example, this analog signal is essential for controlling frequency converters for speed controlled spindles or for power electronics of engraving lasers. Due to many possible configuration options the board can also be used for other projects requiring the conversion of a PWM signal into a pure analog signal.

    The board operating status is symbolized by two LEDs. The board is specially designed to be plugged in between the CNC control system and the machine’s CNC electronics. Most signals, e. g. pulse and direction signals are consistently connected from the LPT input to the LPT output. However, it is also possible to connect the PWM signal via a two-pin plug. A comprehensive documentation for individual applications can be obtained here as soon as possible.


  • Double axis board for controlling two drives for one axis direction Open or Close

    The double axis board has been conceived for a synchronous control of two drive units for one axis direction. However, special care must be taken with two drives for one axis direction during homing and gantry alignment. The double axis board evaluates for each drive the corresponding reference switch and after homing the gantry is exactly re-aligned.

    The board is specially conceived for being plugged in between the CNC control system and the machine’s CNC electronics. The signals which are not needed are consistently connected between LPT input and LPT output. Thus there is no need for extra cabling. Due to various options concerning configuration and a detailed description the corresponding in- and outputs on the board can be individually allocated to unassigned input and output pins. Thus there is no need for changing the acutal assignment and the CNC machine can easily be upgraded with the double axis board.

    A comprehensive documentation for the individual application can be obtained here.

  • Digital I / O card 160802 Open or Close

    The PC/104 I / O card EA 160802 is the ideal solution for all industrial positioning and sequential controls.In addition to 16 optocoupled inputs and 8 optocoupled outputs there are 2 analogue outputs with 0 – 10V. By means of the additional module E/A 160802 all tasks can comfortably be managed, e. g. connecting diverse switches and sensors, the safe switching of peripheral devices or the spindle speed control with an analogue voltage value.

    Digital I / O card EA 160802


    • PC/104 bus, pluggable on axis controller
    • 16 inputs, optocoupled
    • 8 outputs. Optocoupled
    • voltage +/- 10V up to +/- 30V and thus 24VDC suitable for being integrated into the control cabinet
    • switching times ON <25µs OFF <100µs, max 50mA
    • max. current 500mA per channel of digital outputs
    • two analogue outputs 0-10V, 8 bit each

    The additional module EA 160802 is already includedin the axes controllers for industrial application and in all Posi controllers. For other or older axes controllers it can be easily retrofitted and ordered completely with cabling and installation material.

  • Keypads for WinPC-NC Professional Open or Close

    Together with our industrial control system WinPC-NC Professional and the used axes controllers it is possible to apply an external keypad for comfortable movement and setting-up of the CNC machine. Due to a connecting cable with a length of serveral meters, the keypad can be taken and placed near to the machine for directservicing. (...means lug directly at the workpiece). The LC-keypad is an inexpensive alternative compared to other types which are available.

    We provide two types of keypads. The RM-keypad is the professional one and possesses a membrane keyboard and is protected against dust and splashing water. The cheaper LC-keypad provides the identical functions and is conceived for being applied in less dusty enviroments.

  • Cable adapters for conditioning clock/direction signals Open or Close

    The pin assignment concerning clock/direction signals of our complete range of controllers and control programs is preset and fix and cannot be modified. For any kind of controllers and motor drivers with a different pinning we can supply small cable adapters for a corresponding and correct assignment.


    Our control programs always assign the direction signals to pins 2+4+6+8 and the clock signals to pins 3+5+7+9. It might be that other control programs use an other kind of assignment, e. g. Mach3 controls clock/direction in the opposite direction in the standard assignment or in CNCProfi.

    The adapter-C crosses the clock/direction signals. It could be applied for a plant which is currently running with standard assignment, e. g. Mach3 and is now to be used with WinPC-NC or if it is planned to use our stepper motor card Step3S with Mach3.




    This adapter must be employed for all machines withtwo motors on the X-axis for operating them synchronously. The adapter disconnects the clock/direction signals of the 4th axis and leads the control signals of the X-axis also to thepins of the 4th axis. Thus an absolute synchronous movement of the 1st and 4th axis is obtained.



    This adapter must be employed for all machines withtwo motors on the Y-axis for operating them synchronously. The adapter disconnects the clock/direction signals of the 4th axis and leads the control signals of the Y-axis also to thepins of the 4th axis. Thus an absolute synchronous movement of the 2nd and 4th axis is obtained.



    This adapter converts the clock/direction signals into RS422 difference signals, e. g. as required for output stages of Berger Lahr or Siemens. Using this adapter means that there are no additional output lines but four possible inputs. Ideally it should be used in combination with the additional digital I/O card 160802 and is already included as standard in our controllers CNCCONS4 and CNCCONW4.



    All axes controllers and Posi controllers with simple clock/pulse signals are equipped with the adapter-B as a so-called booster and ensures that there is a stable 5V level concerning all LPT output signals and an on-load voltage up to 20mA. The adapter-B can be ordered separately and retrofitted, e. g. on desktop computers at the LPT port.

  • Outbreakboard ASM Open or Close

    Utilizing inputs/outputs at the LPT port. Due to the interface module ASM-LPTR3 it is possible to use in a simple manner the 4 additional digital output signals and the 5 input signals of the LPT port as switching signal. Three 10A relays at the switching outputs as well as the standby-mode and the reinforcement of clock/direction signals isthe ideal basis for controlling any kind of efficient stepper motors. It is the best solution for the automation of machine tools or for the realization of operation projects by using the control programs WinPC-NC or our Posi controllers.

  • PCI-LPT plug-in card Open or Close

    Required for retrofitting a LPT port of desktop computers. The computer must be equipped with a LPT port when our control programs WinPC-NC Light or Win-PC-NC Economy are used. This is the ideal solution if there is no further interface available.

  • Adapter USB-RS232 Open or Close

    For running WinPC-NC Professional and the serial axis controller it is necessary to use a serial RS232 interface on the control computer. If this serial interface is not available, the computer can easily be retrofitted by this USB adpater. Communication is then made via USB-connection and very fast and stable in operation.
