Allen-Bradley | 1746-IB16 Digital DC Input Module

Allen-Bradley 1746-IB16 SLC 500 Digital Input Module

Core Technical Data

• 1746-IB16accepts10-30V DC, ideal for standard24VDC industrial buses.
• Each input draws8mA at24V, keeping total backplane load at0.05A.
• ON delay is8ms typical, OFF delay4ms, for reliable real-time control.
• OFF-state leakage stays below1mA, preventing false high signals.
• Channel power dissipation is0.20W, so heat generation remains minimal.
• Built-in2kV surge suppression protects against factory floor transients.
• MTBF reaches100,000hours at25°C, ensuring long service life.
• Module works from-20°Cto60°C and5-95%non-condensing humidity.
• CE,ULandRoHSmarks simplify global machine certification.

Installation Tips

• Slot the1746-IB16into anySLC500 I/O rack and secure the thumb-screws.
• Use1746-HT or1746-HCA terminal blocks for vibration-proof wiring.
• Connect16gauge single wire or18gauge twin wire to each terminal.
• Torque screws to0.8N·m for gas-tight joints and long-term reliability.
• Leave50mm clearance above for airflow during continuous operation.

Packaging & Shipping

• Box includes oneAllen-Bradley1746-IB16module and removable terminal block.
