Description

The Allen-Bradley 1771-IG is an 8-point TTL Input Module designed for installation in 1771 I/O chassis and integration with low-voltage TTL-level devices. It supports switch-selectable HIGH=TRUE or LOW=TRUE logic and operates with standard 5 VDC TTL signals, providing flexible interfacing with compatible open-collector output devices. With fast input response, built-in filtering, electrical isolation, and individual input status indicators, the module provides reliable digital signal acquisition for industrial control, machine automation, and legacy Allen-Bradley 1771 I/O systems.

Advantages

Compared with conventional digital input modules, the Allen-Bradley 1771-IG provides dedicated TTL-level compatibility, selectable logic operation, fast signal response, and reliable integration with legacy 1771 automation systems.

Provides eight TTL input points for direct connection of low-voltage digital devices within industrial control applications.
Supports switch-selectable HIGH=TRUE and LOW=TRUE logic, allowing the module to adapt to different device logic requirements.
Designed for standard 5 VDC TTL signals, simplifying integration with compatible electronic and open-collector output devices.
Input response of less than 1 ms supports applications requiring fast detection of changing digital signals.
Built-in input filtering helps suppress contact bounce and electrical noise, improving signal stability in industrial environments.
Electrical isolation tested at 1500 VAC helps protect the control system from field-side electrical disturbances.
Individual input indicators and a dedicated logic-status indicator simplify commissioning, diagnostics, and troubleshooting.
Native compatibility with 1771 I/O chassis makes it a practical solution for maintaining, repairing, or extending existing Allen-Bradley legacy control systems.
