1738-IE4CM12 Allen-Bradley ArmorPoint 4-Channel 24V dc Analog Input Module
Description
The 1738-IE4CM12 Allen-Bradley ArmorPoint 4-Channel 24V DC Analog Input Module is a rugged industrial I/O module designed for analog signal acquisition in automation systems. As part of the Allen-Bradley ArmorPoint line, it shares key durability and performance traits with comparable modules from the brand. This 4-channel module accepts 24V DC analog inputs, enabling capture of continuous physical signals such as temperature, pressure, humidity, level, current, and voltage from connected sensors and transmitters, which are typically converted to standard 4-20mA current or 0-10V voltage signals for processing.
Based on comparable Allen-Bradley I/O modules, it likely features robust environmental resilience, including an operating temperature range of 0 to 60 degrees Celsius, non-condensing humidity tolerance of 5-95%, vibration resistance of 1G at 5-200 Hz, and shock resistance of 30G. It may include isolation protection, such as 1500V AC backplane-to-I/O isolation for 60 seconds to suppress electrical interference, and efficient backboard power draw. Additional expected features include user-selectable input filtering to optimize signal response, LED status indicators for quick channel health diagnostics, and built-in short, overload, and overvoltage protection to safeguard connected equipment. It is ideal for discrete, process, and motion control applications in harsh industrial environments.
