- It can be powered with a voltage +5vc or IDC26 PIN or from the USB connector. Compatible with CNC controller board.
- 3 Expansion Ports. It has 3 x IDC26 connector for additional Breakout or Relay Boards.
- IDC 8pin male for analog input
- Visualization of the state of the pins on the display with TCP / IP
- IP configurable
- Display and encoder for configuration
- Din rail mountable
DESCRIPTION
TERMINAL POWER
Regulated 5VDC @0.5A is required to power this board
WARNING : Check the polarity and voltage of the external power source and
connect the 5VDC and GND. Overvoltage or reverse-polarity power applied to
these terminals can cause damage to the board, and/or the power source
MODBUS COMMUNICATION PROTOCOL
