1771-NC6-A Allen Bradley Isolated Analog Cable

The Allen-Bradley 1771-NC6 is a cable used for connecting Remote Terminal Panels or RTPs to Allen-Bradley 1771-N series analog modules.  The Allen-Bradley 1771-N modules are made to work with Allen-Bradley PLC-3, PLC-5, and Allen-Bradley PLC-5/250 programmable controllers when the modules and the programmable controllers are connected with a cable like the 1771-NC6 cable. The 1771-N modules are purpose-built for applications where high resolution and good noise immunity are required. These modules make use of 16-bit analog-to-digital converters and of 14-bit digital-to-analog converters for achieving the desired resolution and precision. The N-series modules are designed and tested to provide 1000V isolation between all the channels, which ensures that noise signals, voltage transients, or shorts/overloads on one channel will not affect any other channel. Calibration is required once a year and can be done from the PLC processor.
