1771-NA01

The 1771-NA01 division node adapter board has been manufactured and designed by Allen-Bradley/Rockwell Automation in the 1771 I/O module series, specifically in the accessories product line. This node adapter provides an interface between external devices and the main control board (MCB) of a specific module. Some of the key characteristics of this board are that it is capable of being configured as a Remote I/O (RIO) interface to be used with different devices that support this technology and it is also compatible with Allen-Bradley processors and modules from the same 1771 series. The Allen-Bradley 1771-NA01 division node adapter board's power is provided by the drive and it generally does not exceed the 5 Volts. It can operate at an ambient air temperature of up to 60 degrees Celsius and at a temperature as low as 0 degrees Celsius and with a humidity level of 5 to 95 percent without condensation.

The Allen-Bradley 1771-NA01 board is a division node adapter board has a smaller surface than other boards but it still comes with all the hardware that performs all the necessary functions for communications with a PLC controller. This board surface is also responsible for the correct functioning of discrete type PLC controller I/O and for block transfers. The Allen-Bradley 1771-NA01 division node adapter board features 2 LED indicators that show the current status of the board. These indicators are a green indicator that shows normal PLC communications between different equipment, while an indicator that is powered off shows that there is no communication to the PLC controller and a blinking green indicator that shows if the PLC is in the reset, program, or test mode. The red indicator glows when there is a malfunction on the board.
