Description
The Allen-Bradley 1734-IB8 is a POINT I/O digital DC input module designed to collect discrete signals from field devices and transmit them to a PLC controller. It features 8 sinking input channels that operate on 24V DC, making it suitable for interfacing with sensors, switches, and other digital devices. As part of the POINT I/O system, it supports distributed I/O architectures, allowing flexible system design and reduced wiring costs.
The module is compact and DIN rail mounted, making it ideal for space-saving installations in control panels. It connects through a terminal base unit (such as 1734-TB or TBS) and offers configurable input filtering for improved signal stability. With reliable performance and easy integration into EtherNet/IP networks via adapters like 1734-AENT, it is widely used in modern industrial automation systems.
