Description
The Allen-Bradley 1771-NIS is a high-resolution I/O module featuring 8 current input channels with a range of 4-20mA, making it ideal for precise data acquisition in demanding environments. It integrates seamlessly with PLC-5/250, PLC-3, and PLC-5 controllers, delivering reliable performance with a maximum power dissipation of 12W and a current draw of 2.4A from the I/O chassis backplane. Providing loop power of 20-30V DC and robust overvoltage protection, this module ensures accurate signal processing with high normal-mode and common-mode rejection rates, while maintaining stability across a temperature range of 0 to 60°C in non-condensing humidity conditions.
