    • Designed for ESS AND ETHER-MACH motion controller.

    • Built-in PWM-Based Speed Control and Two Built-in Electromechanical Relays with NO and NC positions for spindle control.

    • The system monitors:

      • E-Stop

      • Safety Charge Pump.

      • VFD Fault.

      • Driver Fault.

    • Discrete Inputs and Outputs can be using with +5vdc TTL logic or 10-30vdc Logic.

    • Electromechanical Relay with NO and NC positions for general purpose (Port_2 16 or 17, jumper-selectable).

    • Microcontroller based SCHP.

    • Optoisolated inputs.Can be powered with a voltage between +10 and +30VDC.

    • Status LEDs on all input and Output connections.

    • DIN Rail mountable.

    • Pluggable Screw-On Terminals.

    • It is compatible with family of C34 connector boards that allow quickly connecting to popular drives connecting not just the step and direction signals, but also the fault and enable signals.

       Frequently Asked Questions and Answers

    • Arturo Duncan - 4 years ago
      What is a Safety Charge Pump (SCHP)?

      It is a watchdog.  It is a feature in which the control software will send a pulse stream through a pin, as if it was moving an axis.  Then a microcontroller on the breakout board will see that pulse stream and will know that the signals coming from the c...

      I cannot get the green LED to enable on the breakout board

      3 conditions must be met to get the enable LED:   The board must be properly powered.  Check the documentation on the board, as a misunderstanding on how it is powered is very possible. The board must be connected to a PC/Motion Controller which is c...

      US and International modes of operations for VFDs (Variable Frequency Drives) and Speed Controllers

      VFDs and motors have two way of operation, in the US we use CW and CCW, in the rest of the world, or INT (International) it is used START/STOP and DIRECTION. These settings can usually be adjusted VFD settings.  The chances are that if you purchased the V...

      What would be the best hp laptop to use with this Bob running mach 4?

      Mach4 will run very good on most PCs and Laptops but you really need to have an external motion controller.  Like the Ethernet Smooth Stepper, UC300ETH, Ether-Mach or PoKeys. The performance of the processor itself has to do more with the types of operat...

      What is the purpose of the relay when wired to gecko drivers as shown in photo?

      The C82 and most of our cnc4pc breakout boards have 3 relays.  Two of them are intended to for use controlling a VFD and the 3rd one is a general-purpose relay that can be tied to the enable line via the SCHP (Safety Charge Pump), so it can be used to dri...

      Why use Ethernet Connection for my Motion Controller?

      The Ethernet Connection has many advantages over USB.  It is more reliable as Ethernet runs a client-server connection, while USB runs as a Windows Device.  If there happens to be any glitch in the communication, you can lose the USB d...

      Should I use the C76 with the UC300ETH or C82 with the Ethernet Smooth Stepper for my Plasma?

      You can use the C76 or C82, it is a matter of preference. They both work with Mach4. I will try to summarize the basic considerations: The UC300ETH may provide additional flexibility as it can also support UCCNC in addition to Mach3/4. It also depends...

      The Analog Output to the VFD is not stable

      The issue is related to noise coming back from the analog input terminals on the VFD. They are supposed to be isolated, but sometimes noise finds a way. There are two ways of fixing that: - Use shielded cables for the analog and its ground and ground the...

      How do the inputs work on this board?

      The board has 2 banks of input that could be handled independently and isolated from each other and from the board. Each bank of inputs has bidirectional inputs which activate with a voltage between +5vdc and +24vdc. If the signals that you want to ac...

      How does the Spindle Control work on the CNC4PC Multifunction Breakout Boards

      The relays are not directly tied pins in the configuration, as it is the breakout board that is driving the relays based on the step(PWM) and dir received from the controller and the US/INT Mode selected to drive the spindle. Please check this: https://ww...
