Allen-Bradley 1734-IB2 POINT I/O 24 VDC Input Module

The Allen-Bradley 1734-IB2, also cataloged as the 1734-IB2 Input Module, operates as a dedicated hardware component for 24 VDC discrete signal sensing and field device monitoring within POINT I/O system architectures.

Hardware Specifications

Backplane Bus Communication Velocity and Density

• Low POINTBus current draw of 75 mA at 5 VDC minimizes power consumption overhead across dense I/O base assemblies.
• Compact 2-channel sinking input design allows flexible I/O density scaling and channel-level allocation across distributed terminal bases.
• Direct backplane communication maintains predictable firmware execution and deterministic signal transfer speeds to master controllers.

Frequently Asked Questions

Q: What mounting bases are compatible with the 1734-IB2 module?

A: The module installs directly into 1734-TB or 1734-TBS terminal base units.

Q: What is the backplane current draw for the 1734-IB2 on the 5 VDC POINTBus?

A: The module draws a maximum of 75 mA at 5 VDC from the backplane.

Field Installation Guidelines

• Insert the 1734-IB2 module securely into a compatible 1734-TB or 1734-TBS mounting base attached to a grounded 35 mm DIN rail.
• Wire field sensors to the terminal block ensuring DC supply voltage stays within the specified 10 to 28.8 VDC operating range.
• Connect low-voltage signal wiring away from high-voltage AC lines to prevent induced electrical noise on signal channels.
• Confirm that the terminal base and DIN rail assembly are properly earth grounded to ensure continuous 50 V isolation performance.
