PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-NBV1 is an Analog Combination Module for the PLC-5 control system. This unit belongs to the 1771-N analog input and output product line. It provides six analog input channels alongside two analog output channels. The module mounts directly into a standard 1771 I/O chassis slot.
Each analog input channel supports a voltage range of plus or minus 10.5 volts DC. Input impedance exceeds 10 megaohms with continuous overvoltage protection up to 140 volts AC RMS. The two voltage outputs deliver up to plus or minus 10.4 volts into one kiloohm loads. Power consumption totals 8 watts during operation, drawing 1.8 amperes from the backplane.
