Allen-Bradley 1771-RTP4 Remote Termination Panel for N-Series Analog

Product Overview

Allen-Bradley 1771-RTP4 is a remote termination panel used with 1771-N series analog modules. It provides screw-terminal field connections and interfaces to the module via D-shell cables, allowing the I/O module to be removed without disturbing field wiring.

Technical Specs

• Type: Remote Termination Panel (RTP)
• Compatible modules: 1771-N series analog I/O (non-thermocouple applications)
• Connectors: 2 × 25-pin female D-shell
• Field terminals: Screw terminals (straight-through wiring)
• Mounting: DIN-rail
• System: 1771 analog I/O

Key Features

• Separates field wiring from the I/O module
• DIN-rail mounting for clean panel layout
• Supports current or voltage inputs (with optional resistors)
• Simplifies module replacement

FAQ

• Use with? 1771-N series analog modules.
• Mounting? DIN rail.
• Thermocouple? Not intended for TC applications (use specific RTP variants).

Installation Guide

1. Mount the RTP on a DIN rail near the field wiring.
2. Connect the D-shell cable(s) between the RTP and the 1771-N module.
3. Wire field signals to the screw terminals.
4. Add range resistors if converting current to voltage as required.
5. Verify continuity and signal integrity.

Selection Tips

• Select the correct RTP variant for the analog module type.
• Use for applications requiring remote termination of analog signals.
• Keep matching cables as spares.
