Allen-Bradley 1715-IF16 ControlLogix Analog Input Module

Description

The Allen-Bradley 1715-IF16 ControlLogix Analog Input Module is a high-performance industrial automation module designed for critical process control and redundant systems. It features 16 independent analog input channels that support multiple industry-standard signals, including ±10V, 0-10V, 0-5V, 0-20mA, and 4-20mA, enabling flexible data collection for complex industrial scenarios. The module offers configurable channel modes: 16 single-ended channels, 8 differential channels, or 4 high-speed differential channels to match diverse wiring and signal requirements.

Built for high reliability, it supports duplex redundant operation, with dual modules working in parallel to achieve fault tolerance; single-point failures will not disrupt system operation. It also includes hot-swap functionality, allowing module replacement without shutting down the system to maximize uptime. Key technical specifications include a working voltage range of 18–260V DC, a rated power current of 32mA, and 50V continuous isolation to suppress electrical interference. With 16-bit resolution, it delivers high measurement accuracy, reaching ≤0.15% of full scale for current signals at 25 degrees Celsius, and supports fast data update rates down to 8ms for real-time control applications. It offers multiple data formats, including integer (two’s complement, left-aligned) and IEEE 32-bit floating point, for seamless integration with different control systems.
