Specification

SEODescription

The Rockwell 1762-IR4 module is a high-precision analog input expansion unit designed for integration with MicroLogix 1200 and 1500 controllers. This 1762-IR4 analog input module features four isolated channels, supporting both current (4–20 mA) and voltage (0–10V DC) signals with 16-bit resolution for accurate data acquisition. It connects directly to MicroLogix systems via a compact backplane interface and operates within a 24V DC power range, ensuring compatibility with industrial power standards. The MicroLogix 1762-IR4 excels in harsh environments, functioning reliably between 0°C and 60°C, making it ideal for manufacturing automation, process control, and HVAC applications. Its key advantages include easy configuration via Rockwell software, robust noise immunity, and compact form factor. However, limitations include a fixed channel count and lack of built-in communication protocols beyond the base controller’s capabilities.
