Allen Bradley 1734-RTB3S Terminal Block Assembly

The Allen-Bradley 1734-RTB3S, also cataloged as the 1734-RTB3S Replacement RTB, operates as a dedicated hardware component for field wiring termination within POINT I/O 1734 platforms.

Hardware Specifications

Backplane Signal Termination and Network Synchronization

• The Allen-Bradley 1734-RTB3S provides direct physical execution for high-density signal termination across EtherNet/IP deterministic networks.
• The 12-terminal spring-clamp architecture scales I/O wiring density while ensuring constant tension force to resist vibration-induced contact degradation.
• Galvanic protection is maintained through a continuous 250 V isolation voltage rating between the field-side wiring loops and internal backplane logic circuitry.
• Seamless firmware flash compatibility is maintained across primary controller drops due to the fully passive electrical passthrough construction of the base unit.

Frequently Asked Questions

Q: What wire size range is supported by the 1734-RTB3S spring-clamp terminals?

A: The spring-clamp mechanism accepts solid or stranded conductors spanning from 28 AWG to 14 AWG.

Q: What are the maximum electrical current and voltage limits for signal terminals on this unit?

A: Signal terminals support up to 30 V maximum signal voltage and 2 A maximum signal current, while the main field supply capacity supports up to 300 V and 10 A.

Field Installation Guidelines

Mount the base assembly onto a standard 35 mm DIN rail connected directly to earth ground via a low-impedance connection. Strip conductor insulation to the specified length and insert wire ends straight into the spring-clamp terminals using a standard screwdriver to actuate the release spring. Route all 24 VDC and signal cables through dedicated wiring channels separate from high-voltage AC power lines to prevent EMI noise coupling. Ensure operating environments remain within the -20 to +55 deg C temperature limit and do not exceed non-condensing relative humidity thresholds.
