POINT I/O (1734) adapters, I/O modules and bases

18 Allen-Bradley POINT I/O (1734) catalog numbers, each with the ratings and the lifecycle status shown on its Rockwell product page (read on 3 November 2026). TDL quotes these parts as spares or as part of a project, and handles configuration, programming and commissioning on site.

POINT I/O 1734 modules are small 2-, 4- and 8-channel modules that connect to an EtherNet/IP network through a 1734-AENT (1 port) or 1734-AENTR (2 ports) adapter.
POINT I/O modules mount on a terminal base such as 1734-TB (removable IEC screw terminals).

How to read the catalog number

In 1734 digital modules, B = 24 V DC sink input (1734-IB8), V = 24 V DC source input (1734-IV8), A = AC (1734-IA2, OA2), W = relay (1734-OW4); E suffix = electronically protected output (1734-OB4E); analog C = current, V = voltage (1734-IE2C, IE2V), as given in the descriptions.
