Highly Expandable:
Full of Features
• Can ship the UC300ETH Motion Controller installed when purchased as a bundle.
• Emulates 5 Parallel Ports.
• 3 Expansion Ports for connecting additional breakout or relay boards.
• Two Analog Inputs and Two Outputs.
• 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.
• Electromechanical Relay with NO and NC positions for general purpose or tied to the Enable Signal (Port_2 16 or 17, jumper-selectable).
• Microcontroller based Safety Charge Pump (SCHP).
• Optoisolated inputs working at 5-24VDC.
• Uses a single 24VDC to power the system. It generates the isolated voltage for the spindle control circuit and +5vdc for circuits using TTL logic.
• Status LEDs on all Input and Output connections.
• DIN Rail mountable.
• Open Collector Outputs pins 1, 14, 16, 17 on port 2.
• Screw-On connections for all terminals.

Frequently Asked Questions and Answers
- 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...
Read more - Can the C-94 be used with Gecko 320X?
You could, but it will be very difficult to wire the error/fault line. I suggest you consider the C76 which is made for this as it can use the C34G320.
Read more - 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...
Read more - How do I verify if the UC300ETH is receiving power?
You can verify if the UC300ETH is receiving power by meaning the voltage at the pin with the +5vdc and using any of the pins with grounds as reference.
Read more - 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...
Read more - Do I need an additional UC300ETH? Isn't there one built into the C94 itself?
You have the option of adding it once you hit the "Customize and Add to Cart" button. You can also add DIN Rail Support and Control Software. When you purchase the units together, we ship them assembled.
Read more - Is the UC300ETH included with the C94?
Yes, you can choose to add it or not on checkout to give the option to users who already own a UC300ETH to get the board without purchasing a UC300ETH again. If you purchase it as a bundle, it will come with the UC300ETH preinstalled.
Read more - 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...
Read more - 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...
Read more - Will this work with LinuxCNC?
No, it will not work with LinuCNC. It will work with Mach3, Mach4 and UCCNC.
Read more - Using Relays 1 and 2 as General-Purpose Relays
Relays 1 and 2 are intended to be used for controlling the VFD or Speed Controller and are intended to activate the FOR and REV signals (US MODE) or the ON/OFF and CW/CCW (INTernational MODE). But if you do not need to control the VFD, but intend to...
Read more - Will the UC300ETH work with Mach4. If not, will it be supported down the road?
Yes, it works with Mach4. Note that there are some compatibility issues with the current version of Mach4, and an older version is recommended at this time. Please check these instructions which contain a link to the version that is recommended: https:/...
