PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1734-MB/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1734-MB is a POINT I/O I/O Mounting Base designed for distributed automation systems. It provides backplane communication and field-power bus distribution across the POINTBus backplane. The unit establishes mechanical and electrical connections for POINT I/O hardware on standard 35 mm DIN rails.
This mounting base accepts an 8-contact removable terminal block for field wiring termination. It features mechanical keying and a locking screw to prevent mis-insertion and secure mounting. The base is compatible with all 1734 POINT I/O modules, adapters, and power supplies.
