The Allen-Bradley 1762-IR4 is a versatile four-channel analog input module designed specifically for interfacing with Resistance Temperature Detectors (RTDs) and resistance-generating devices, making it ideal for temperature and displacement measurement applications. Compatible with a wide range of RTD types, including Platinum, Copper, and Nickel variants, this module supports 2-Wire, 3-Wire, and 4-Wire configurations, and can accommodate resistance ranges from 0 to 3000 ohms. It features Delta-Sigma conversion for precise analog input data processing, and includes a single diagnostic LED for status and power indication, while auto-calibration and programmable calibration intervals ensure optimal performance. This Allen-Bradley module seamlessly integrates with MicroLogix 1100, 1200, and 1400 controllers, allowing for expanded functionality within these systems.
