Allen-Bradley Point I/O series 1734 POINT I/O-I/O Modules

Allen-Bradley Point I/O series is a series of products for industrial automation control under Rockwell Automation, with the following features:

High flexibility: supports independent selection of I/O and network interfaces, has a variety of terminal options, and provides a faster and safer connection method.

Modular design: The system is highly modular, and the components are small and compact, which can realize low-cost distributed I/O system expansion and facilitate maintenance and replacement of parts.

Multiple functional modules: including digital input and output, analog input and output, special function modules and safety I/O modules, etc., can meet various industrial application requirements.

Easy to install: supports DIN rail installation, can be installed horizontally or vertically, and can adapt to small installation spaces.

Powerful diagnostic functions: Standard digital input and output modules have module-level diagnostic functions, such as short circuit and open loop detection; each channel of the analog module has a software-adjustable input filter, which can improve the performance of the module when dealing with unstable or rapidly changing process variables.

Common models in this series are as follows:

Communication module

1734-AENT: Ethernet communication adapter for linear Ethernet topology.

1734-AENTR: Ethernet communication adapter for redundant Ethernet communication.
