1734-IB8K Digital Input Module | Allen-Bradley POINT I/O

Product Description

The Allen-Bradley 1734-IB8K is an 8-point 24 V DC digital input module from Rockwell Automation’s Bulletin 1734 POINT I/O family. It is designed to acquire discrete field signals from devices such as push buttons, proximity sensors, limit switches, and other on/off DC signal sources in distributed I/O systems.

The “K” suffix indicates a conformal-coated version, providing enhanced protection against moisture, dust, and corrosive atmospheres. This makes the 1734-IB8K particularly suitable for harsh industrial environments such as food and beverage processing, chemical plants, wastewater facilities, and outdoor or semi-outdoor installations.

The module uses sinking (current-sinking) inputs and integrates seamlessly with POINT I/O adapters for use with ControlLogix, CompactLogix, and other EtherNet/IP-based control architectures.
