Information About 1756-IG16
The 1756-IG16 is part of the Allen-Bradley ControlLogix I/O family engineered for modular and scalable control architectures. It is constructed as a chassis-mounted input module using a 20-pin interface and removable terminal blocks for structured wiring. The module integrates directly into ControlLogix racks and communicates over the ControlLogix backplane for deterministic control. It is typically used in applications requiring TTL-level digital input monitoring, such as interfacing with electronic devices, encoders, and logic-level controllers.
Key Features:
- 16 digital input points: Supports high-density TTL signal monitoring.
- TTL voltage compatibility: Accepts 0–5 V DC logic-level signals.
- Low-true logic operation: Designed for low-level logic detection.
- Sourcing input configuration: Suitable for TTL source-type devices.
- Fast input response: 0.25 ms input delay plus configurable filtering.
- Grouped input design: Organized into two groups for structured wiring.
- ControlLogix backplane interface: Ensures deterministic data transfer.
The 1756-IG16 delivers the reliability and precision required for low-voltage digital signal acquisition in ControlLogix automation systems.
