Allen-Bradley 1756-IB16 ControlLogix DC INPUT Module 16 Pt 24VDC

Description:

The Allen‑Bradley 1756‑IB16 ControlLogix DC input module is used in industrial automation systems to acquire discrete 24 VDC field signals and interface them with a ControlLogix programmable controller. It is commonly installed in 1756 ControlLogix chassis and control cabinets to read input statuses from sensors, switches, and field devices. Maintenance teams and system integrators use this module for I/O expansion, system upgrades, and replacement of failed input modules.

Applications:

The Allen‑Bradley 1756‑IB16 module is widely used in factory and process automation environments requiring reliable acquisition of discrete signals. It is commonly found in conveyor systems, packaging machinery, assembly lines, material handling equipment, and safety interlock systems where 24 VDC inputs from proximity sensors, pushbuttons, limit switches, and other field devices provide status data to PLC logic for monitoring and control.
