    4. CONNECTION DIAGRAM FOR LIMIT SWITCH AND BREAKDOWN SWITCH Input port pins are opto isolated and use isolated 5 Volts (VCC) for up to 1000V isolation thus helping to protect your PC or control electronics. You can connect up to 5 lines with limit switches, emergency Stop switch, reset etc. you can connect sensors for robots etc.
     
    Our breakout board can be used to connect up to 5 Stepper Motors, or control 11 control output Lines and 5 input signals and can be powered from a voltage range of 7 to 36 Volts giving a large degree of flexibility and can be directly powered from our range of CNC PSU's consisting of 36 Volt 400Watt to our 48 Volt 500Watt or 600Watt Switch mode power supplies,
    On board power regulation is provided by using the LM2576HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (Buck) switching regulator, capable of driving 3A load with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required as in our circuit as we are only using 300mA. Other features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50mA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. This then feeds a 1Watt isolated DC/DC converter B0505LS-1W with a high Efficiency up to 80% and 1KVDC Isolation to further enhance protection from machine to PC interface. All outputs with the exception of the Enable line (74HC14 output) use the 6N137 single channel optocouplers consist of a 850 nm AlGa AS  LED, optically coupled to a very high speed integrated photo-detector logic gate with a strobable output. This output features an open collector, thereby permitting wired OR outputs. The coupled parameters are guaranteed over the temperature range of -40°C to +85°C. A maximum input signal of 5mA will provide a minimum output sink current of 13mA (fan out of 8). An internal noise shield provides superior common mode rejection of typically 10kV
    If you are using in an industrial or noisy environment or plasma systems we recommend using a front end filter and separate regulated PSU of between 9V and 24Volts.
     
    Standard parallel port with onboard noise suppression and buffering using the 74HC14 high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology all the inputs have 20% VCC hysteresis level. This, together with its Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals wide operating range of high input voltage typically about 2.7Volts makes these boards more likely to accommodate new PC output levels but no guarantee can be given or presumed due to large variations in operating environments and design constraints on modern systems. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
     
    Including relay control, it can switch your spindle motor, coolant pump etc. this is rated at 10Amps at 277VAC and 12Amps at 125VAC which can be used to switch upto 2KWatts non inductive at 240VAC. This is a standard normally open output from this relay which can be used to switch on low voltage 24VDC from our range of VFD's to start spindle automatically under mach3 control upto switching directly our range of Kress spindles. Input power supply voltage can be in the range of 7V - 36V power supply, you can use your regulated DC motor PSU if not exceeding 36 Volts.
