1756-IF16 /A DescriptionThe 1756-IF16/A is a high-density, 16-channel analog input module from Allen-Bradley's ControlLogix family. Designed for industrial automation systems, it provides precise measurement and conversion of analog voltage or current signals from field sensors (e.g., temperature, pressure, flow) into high-resolution digital values for the ControlLogix controller. This module ensures reliable data acquisition, flexible configuration, and seamless integration into demanding process control and monitoring applications.
1756-IF16 /A Features
High Channel Density: 16 single-ended or 8 differential input channels in a single slot, optimizing control cabinet space.
High Resolution & Accuracy: Delivers 16-bit resolution with high accuracy and low drift, ensuring precise measurement for critical processes.
Flexible Input Ranges: Configurable per channel for various voltage (e.g., 0-5V, ±10V) and current (e.g., 0-20mA, 4-20mA) signal types.
Advanced Diagnostics: Features channel-level diagnostics (open wire, over-range, under-range) and module health status for simplified troubleshooting.
Electronic Keying: Supports compatible, exact, or disable keying modes to prevent incorrect module replacement and ensure system integrity.
Seamless Integration: Native integration with ControlLogix controllers via the backplane, supporting real-time data exchange and producer/consumer model communication.
