The ACE series PLC's from Velocio.Net are powerful, easy to use pocket sized PLC.
The programming software is free and an off-the-shelf USB cable will make the connection between PLC and PC. Software is also available to create HMI displays for a Windows PC which can show real-time process values for output and buttons / sliders for input.
Programming can be done via ladder-logic or drag & drop with flowcharts.
We chose this specific PLC since it can support up to 3 stepper drivers with a total of 250 kHz. This will allow many of our customers to use an industrial grade device to control simple processes with 6- 12 digital inputs and digital outputs, RS232 and RS485 communication
The base model starts with 6 inputs and 6 outputs.
We will be adding more accessories shortly - in our excitement we ordered the PLCs without optional accessories.
