About 1791-N4V2
The Allen-Bradley 1791-N4V2 Analog Block I/O Module is a 6-channel module with 4 user-configured inputs and 2 factory-configured voltage outputs. This I/O block belongs to the Allen-Bradley 1791 Block I/O family of compact, self-contained and sustained Block I/O modules that are designed for controlling I/O devices installed in a remote location from a processor. The 1791-N4V2 Analog Block I/O Module communicates via discrete or block transfers with a controller via the Remote I/O network. The 1791-N4V2 Block I/O Module has a removable terminal strip that allows for simplified wiring of the Remote I/O link and the power and I/O blocks, and it has 2 switch assemblies that are used for configuring block parameters and transfer rates. The 1791-N4V2 Block I/O Module has 4 user-configurable 14-bit analog inputs with 108 milliseconds of maximum update time and about 0.1% absolute accuracy at 25.0 degrees Celsius. Each input channel has a voltage/current impedance rating of 10.0 Megaohms/250 Ohms and a common-mode rejection value of -75 Decibels (dB).
The Allen-Bradley 1791-N4V2 Block I/O Module also has 2 analog output circuits (14-bit) that are factory-configured for voltage output. Each output channel has an output voltage range of +/-10 Volts DC (14-bit) and an impedance rating that is less than 1.0 Ohm. All of the 1791-N4V2 Block I/O Module outputs have 0.1% absolute accuracy and 0.05% linearity at 25 degrees Celsius. The 1791-N4V2 Block I/O Module outputs offer continuous short-circuit protection and about +/-10.0 Volts DC output voltage compliance for a load greater than or equal to 1 Kiloohm. The 1791-N4V2 I/O block has an internal 24 Volts DC current-limited power supply (20 to 28 Volt DC unregulated voltage at 100 milliamps) for integrating loop-powered current transducer inputs. This Block I/O module also supports an external 120 Volts AC power supply with an 85 to 132 Volts AC supply range, a 100 milliamps current rating, and a 16.9 Watts maximum power dissipation rating.
The Allen-Bradley 11791-N4V2 Block I/O Module is a 64-point I/O module designed to control external devices that are connected on the remote I/O link. This module has 4 user-configurable inputs and 2 factory-configured voltage outputs.
