Allen-Bradley 1734-RTB3 POINT I/O Removable Terminal Block Base

The Allen-Bradley 1734-RT3, also cataloged as the 1734-RTB3 Mounting Terminal Block Base, operates as a dedicated hardware component for field wiring termination and signal routing within POINT I/O 1734 platforms.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

• The Allen-Bradley 1734-RTB3 facilitates high-density terminal terminations directly interfacing with the POINTBus backplane, supporting high-speed backplane bus communication velocity across EtherNet/IP deterministic networks.
• The 12-terminal cage-clamp architecture allows maximum I/O density scaling while isolating high-speed logic signals from potential field-side transient electrical interference.
• Firmware flash compatibility across primary controller platforms remains unaffected due to the fully passive mechanical and electrical passthrough design of the base assembly.

Frequently Asked Questions

Q: Does the 1734-RTB3 terminal block base support hot-swapping or Removal and Insertion Under Power (RIUP) of the associated I/O module?

A: Yes, the removable terminal block assembly allows the I/O module to be installed or removed without disturbing the field wiring termination assembly, provided proper safety procedures for field power isolation are followed.

Q: What environmental protection rating does the 1734-RTB3 assembly provide when installed?

A: The terminal base assembly carries an IP20 ingress protection rating, requiring installation inside an enclosure offering suitable protection against dust and liquid contaminants.

Field Installation Guidelines

Mount the 1734-RTB3 base securely on a standard 35 mm DIN rail connected to earth ground via a low-impedance connection. Strip field conductor leads to specified strip length guidelines before securing them into the 12-terminal cage-clamp screw connections. Ensure field signal cables are routed separately from high-voltage AC lines or noisy motor drive cables to prevent electromagnetic coupling. Verify that all terminal screws are tightened according to recommended torque specifications to maintain continuous electrical contact under vibration.
