Product Description
The Allen-Bradley 1756-IF16K is a high-density ControlLogix® analog input module engineered for precise data acquisition in demanding industrial environments. The "K" suffix indicates that this module features a factory-applied conformal coating, providing superior protection against moisture, chemical vapors, and salt spray, which is essential for offshore, wastewater, and heavy chemical processing applications.
This module is highly versatile, supporting multiple input modes including 16 single-ended channels, 8 differential channels, or 4 high-speed differential channels depending on the wiring configuration and software setup. It accurately converts analog signals from pressure transmitters, flow meters, and temperature sensors into 16-bit digital values. With integrated hardware diagnostics and support for multiple voltage and current ranges, the 1756-IF16K ensures long-term signal integrity and system reliability within the Logix ecosystem.
