More Information

Overview Manuals Terminal Mapping Shielding Conversion Use Application
  • Provides eight channels of remote field termination for high-resolution analog signals
  • Organizes input, return, shield, and spare wiring away from the 1771 chassis
  • Supports documented retention of existing field wiring in selected 1771-to-1756 conversions

1771-RTP4 is an Allen-Bradley high-resolution analog remote termination panel used in PLC-5 control systems.

The panel separates field-device termination from the 1771 chassis, supporting maintainable analog wiring and documented conversion paths to selected ControlLogix analog modules.

Before installation or replacement, verify the exact 1771 analog module, channel signal type, RTP terminal map, cable catalog and length, shield jumpers and grounding, enclosure location, field wiring, and any 1771-to-1756 conversion drawing.

Availability, condition, price, and shipping time for 1771-RTP4 are confirmed during quotation.

  • Signal terminals are assigned by channel and by the connected analog-module function
  • W1, W2, and W3 are spare terminals for field-wiring convenience
  • The exact terminal map must be taken from the applicable module or conversion drawing
  • Channel shields connect to the panel shield arrangement
  • The panel shield connection is bonded to the cabinet grounding point as documented
  • Ground loops and shield treatment must be reviewed before modifying installed wiring
  • Official conversion drawings retain the existing 1771-RTP4 in selected migrations
  • The required 1492 conversion cable depends on the original and replacement analog modules
  • All drawing notes and application limits must be reviewed before commissioning
  • Remote termination of eight-channel high-resolution 1771 analog field wiring
  • Maintenance of PLC-5 N-series analog input and mixed-signal installations
  • Selected 1771-to-ControlLogix analog conversions that retain the existing RTP4 panel
Description
1771-RTP4 is an Allen-Bradley high-resolution analog remote termination panel for the PLC-5 platform.

It concentrates sensor, return, shield, and spare field terminals at a remote panel and connects compatible high-resolution isolated analog modules through the specified cable assembly.

Before installation or replacement, confirm the exact 1771 analog module, channel signal type, RTP terminal map, cable catalog and length, shield jumpers and grounding, enclosure location, field wiring, and any 1771-to-1756 conversion drawing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can I confirm that Allen-Bradley 1771-RTP4 is the correct replacement for my existing termination panel?
Check the complete catalog number on the existing panel, the connected 1771 N-series analog module, the signal type used by each channel, and the installed cable. Do not select a replacement solely because the connectors and terminal layout appear similar.
Are the module cables supplied with Allen-Bradley 1771-RTP4?
Cables should be treated as separate items unless they are specifically included in the quotation. Before ordering, confirm whether the installation requires a 1771-NC6 or 1771-NC15 cable and inspect any existing cable for damaged pins, retaining screws, or connector housings.
Can existing 1771-RTP4 field wiring be retained during a ControlLogix migration?
It may be retained when the original module, replacement ControlLogix module, and 1492 conversion cable form a combination documented by Rockwell Automation. Verify the applicable conversion drawing before ordering because connector compatibility alone does not confirm the channel mapping.
Why does a signal remain incorrect after replacing the connected analog module?
Allen-Bradley 1771-RTP4 uses straight-through wiring and does not scale or convert the signal. Verify the replacement module configuration, terminal assignment, signal polarity, external resistor requirements, field-device power, and cable connection before suspecting the termination panel.
What should be checked when readings connected through Allen-Bradley 1771-RTP4 are noisy or unstable?
Check terminal tightness, cable connector seating, shield continuity, grounding practice, separation from high-voltage wiring, field-device power, and the analog module configuration. Test the affected channel at the field terminals and module side to determine whether the disturbance originates in the field circuit, cable, or module.
What must be considered before using Allen-Bradley 1771-RTP4 in a thermocouple application?
Do not treat it as a direct thermocouple termination panel because it does not provide built-in cold-junction compensation. Use a termination panel designed for the applicable thermocouple module or provide the separately documented cold-junction compensation method required by the complete measurement system.
What should be documented before replacing Allen-Bradley 1771-RTP4?
Photograph and record every terminal, shield jumper, ground conductor, cable catalog and length, connected module, channel signal type, spare-terminal use, and any conversion-module wiring.
