  • Product Item : 1791-N4C2
  • Product Brand : Allen-Bradley
  • INQUIRY

The 1791-N4C2 module is a 6-point analog module manufactured by Allen-Bradley. The Block I/O module comes with a power rating of 120 Volts AC, with up to 4 analog inputs and 2 current outputs. The 1791-N4C2 module features an input impedance of 10 Megohms and an absolute accuracy of 0.1% at 25 degrees Celsius. The unit features 2 outputs per block, with the output impedance at less than 1 ohm. The 1791-N4C2 module is manufactured to ensure compatibility with the PLC-2, PLC-3, and the PLC-5/250 programmable controllers. The 1791-N4C2 module is designed to communicate through the block transfer or a discrete transfer with various Allen-Bradley programmable controllers that connect to an I/O network. The 1791-N4C2 module also communicates with the SLC family controllers through a discrete transfer process. The 1791-N4C2 module's 4 independent inputs can be easily configured as all voltage inputs or as all current inputs.
