Description
The Allen-Bradley 1756-IB16I is a high-performance 16-point digital input module designed for the ControlLogix platform. This module provides individually isolated inputs, allowing for flexible wiring configurations and enhanced noise immunity in demanding industrial environments. It is engineered to interface with 10-30V DC signals, making it suitable for a wide range of sensor and switch monitoring applications within automated control systems.
Features
- 16 individually isolated digital input points.
- Operating voltage range: 10-30V DC.
- Standard ControlLogix form factor for seamless integration into 1756 chassis.
- High-density I/O design to optimize cabinet space.
- Compatible with standard 36-pin removable terminal blocks (RTB).
Applications
This module is widely utilized in industrial automation applications requiring robust signal isolation, including:
- Process control and manufacturing lines.
- Monitoring of field devices such as proximity switches, pushbuttons, and limit switches.
- Applications where electrical isolation between input channels is required to prevent ground loops or interference.
- Integration with complex PLC architectures requiring reliable DC signal acquisition.

Installation Guidelines
- Ensure the ControlLogix chassis is powered down before inserting or removing the module to prevent electrical damage.
- Verify the module is fully seated in the chassis slot and secured with the top and bottom latches.
- Use appropriate shielded cabling for input signals to minimize electromagnetic interference (EMI).
- Ensure proper grounding of the chassis and power supply common to maintain signal integrity.
- Handle the module using ESD-safe practices to prevent damage to internal electronic components.
FAQ
What does 'individually isolated' mean for this module?
Individually isolated means that each of the 16 input channels is electrically separated from the others, which helps prevent cross-talk and protects the system from ground potential differences between field devices.
Is the 36-pin terminal block included?
Typically, the removable terminal block (RTB) is sold separately or included based on specific regional packaging; please verify your order contents if you require a new RTB.
