More Information

Overview Manuals Signals Installation Termination Application
  • Eight current-input channels are documented for the 1771-NIS base module
  • The module supplies loop power for the documented 4...20 mA input arrangement
  • Field wiring is routed through a compatible remote termination panel and N-series cable

1771-NIS/B is the requested listing identity for an Allen-Bradley 1771-NIS high-resolution isolated analog input module.

Official documentation for the base module specifies eight 4...20 mA inputs, module-supplied loop power, and remote termination through the N-series cable and panel architecture.

Before installation or replacement, verify the physical product label, complete catalog number, hardware series, PLC-5 chassis compatibility, RTP type, cable, field wiring, and channel configuration.

Availability, condition, price, and shipping time for 1771-NIS/B are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • The documented 1771-NIS base module provides eight 4...20 mA current-input channels
  • Each input can be configured for sourcing or sinking operation
  • The module supplies loop power for sourcing inputs; external loop power is used for sinking inputs, with no external resistors required
  • Compatible chassis include 1771-A1B, A2B, A3B, A3B1, A4B or later, plus 1771-AM1 and 1771-AM2
  • Install the module in any I/O module slot except the extreme left slot reserved for the processor or adapter
  • Keep the analog module away from AC or high-voltage DC modules and do not share an I/O group with high-density discrete I/O when using 2-slot addressing
  • The official selection data identifies 1771-RTP4 for the base module
  • 1771-NC6 provides the documented 6 ft N-series cable option
  • 1771-NC15 provides the separately documented 15 ft cable option
  • Eight-channel 4...20 mA process-signal acquisition in a compatible PLC-5 I/O system
  • Isolated current-input installations using module-supplied loop power
  • Remote field termination through a compatible 1771 N-series panel and cable
Description
1771-NIS/B is the requested listing for an Allen-Bradley 1771-NIS high-resolution isolated analog input module in the PLC-5 I/O platform.

Official base-catalog data specifies eight 4...20 mA inputs, 0.34 microampere-per-bit resolution, module-supplied loop power, and remote termination through the N-series interface.

Before installation or replacement, confirm the complete nameplate catalog number, hardware series, chassis, remote termination panel, cable, field-power arrangement, and saved channel configuration.
