Description

The 1771-RTP4 is an Allen Bradley Remote Termination Panel designed for use with 1771-N Series High Resolution Isolated Analog I/O modules in PLC-5 control systems. The 1771-RTP4 is specifically designed for use with 1771-NOC (1) High Resolution Isolated Analog Output modules, providing proper signal termination and routing for current output applications. The 1771-RTP4 connects to 1771-N Series I/O modules via 1771-NC6 (6ft) or 1771-NC15 (15ft) cables, enabling flexible installation distances between the I/O module and the remote termination panel. 

The 1771-RTP4 is for mounting on standard DIN 1 or DIN 3 mounting rails, facilitating organized and professional control cabinet installations. The 1771-RTP4 includes spare terminals (W1, W2, W3) used for field wire convenience, providing additional connection points for wiring flexibility. The 1771-RTP4 can be used in conversion solutions from 1771-N Series I/O to 1756 ControlLogix I/O via 1492-CONACAB cables, allowing system upgrades without removing existing field wires from the termination panel.

The Allen-Bradley 1771-RTP4 Remote Termination Panel is a field wiring interface for 1771 I/O and PLC-5 systems, providing centralized signal termination between field devices and I/O modules. Its panel-mounted design simplifies installation, improves wiring organization, and facilitates maintenance in industrial automation applications.
  • Process Control: Routes voltage/current signals reliably to automation equipment in continuous processes
  • Water/Wastewater: Terminates flow meters, pressure transducers, and valve positioners with clean isolation
  • Power Generation: Monitors engine/facility temperatures using RTD inputs
  • Legacy Modernization: Maps PLC-5 field wiring to modern ControlLogix systems via conversion modules

Wire Stripping: Strip the insulation off your field wires according to specifications (typically 6–8 mm). 
Terminal Connections: Connect your field device wires directly to the screw terminals on the RTP. Be sure to follow your specific module’s wiring diagram to correctly assign the I/O signals, Commons, and Grounds. 
Torque Rating: Tighten the terminal screws firmly. Most 1771 termination panels require a torque of 0.5 Nm (7 lb-in). 
Shielding: If using shielded cables, ensure that the cable shield is connected to the ground terminal at the RTP or I/O module end (not both) to prevent ground loops. 

Technical notes

The 1771-RTP4 serves as an interface module for current output signals, with proper shield grounding and signal routing capabilities for analog output applications. The 1771-RTP4 is part of the 1771-N Series I/O wiring system that includes variations of remote termination panels (RTP1, RTP3, RTP4) depending on the type of module used. The 1771-RTP4 provides a reliable interface between field devices and the 1771-NOC analog output module, ensuring proper signal integrity and ease of maintenance in industrial control applications.

FAQs

  • What is the 1771-RTP4?

    +
    The Allen-Bradley 1771-RTP4 is an 8-channel remote termination panel designed for use with high-resolution 1771 N-Series analog I/O modules in PLC-5 systems.
  • What is the difference between the 1771-RTP3 and the 1771-RTP4?

    +
    Both are used with N-series analog modules, but the 1771-RTP3 is specifically designed for cold-junction compensation required for thermocouple applications. The 1771-RTP4 is a general-use block for all other applications and does not support thermocouples.
  • Are voltage inputs supported?

    +
    Yes, but voltage signals require an external resistor to convert them into a readable signal (like 4-20mA or current signals) before they hit the terminal.
  • Can the 1771-RTP4 be used with modern ControlLogix (1756) systems?

    +
    Yes, the 1771-RTP4 is often utilized in legacy migration setups. You can interface it directly with modern 1756 ControlLogix modules (like the 1756-IF8I) using specialized conversion cables like the 1492-CONACAB series.
