Overview
The Allen-Bradley 1734-IB4 is a 24V DC 4-point digital input sink module designed for the POINT I/O distributed I/O architecture. This compact DIN rail-mounted module accepts field-level sinking digital inputs and communicates through DeviceNet, PROFIBUS, ControlNet, or Ethernet adapters. It provides real-time input status monitoring with four independent LED indicators and integrates seamlessly into CompactLogix, ControlLogix, and other Rockwell Automation controllers via the appropriate communication adapter.
