MPN: 1756-IB16 — industrial control spare part, in stock at TGK Parts.
The 1756-IB16 is the Allen-Bradley ControlLogix 16-point 24V DC sinking/sourcing input module — the standard discrete input card for ControlLogix 5570/5580 racks in North American and European machine builds. It accepts both sinking (PNP) and sourcing (NPN) field wiring, which makes it a drop-in replacement across thousands of panels.
Every unit is bench-tested on all 16 points with a signal generator before shipping. New (sealed) and tested refurbished stock available, with a 12-month warranty.
