Allen-Bradley 1738-IB8M12 ArmorPoint 8 Point Input Module

The Allen-Bradley 1738-IB8M12 ArmorPoint 8-Point Input Module is a rugged digital-input device for ArmorPoint I/O that provides eight 24 V DC sinking input channels. Each channel accepts a 24 V DC signal from field devices such as switches, sensors, or proximity sensors, enabling reliable state sensing on automation lines. The module uses ArmorPoint's DC Micro (M12) field wiring interface and is designed for on‑machine distributed I/O installations, supporting Rockwell Automation control systems in harsh environments. It is sealed to IP69K, offering protection against dust, moisture, and high-pressure washdown typically found in food and beverage, manufacturing, and packaging settings. The 1738-IB8M12—identified by the ArmorPoint 8 DI designation—integrates with ArmorPoint I/O baselines and the broader Rockwell ecosystem to deliver straightforward digital input signaling from 24 V DC devices. Common applications include door interlocks, hazard sensors, limit switches, and other 24 V DC sensors on conveyors, presses, and material-handling equipment where compact, sealed I/O is advantageous.
