Allen-Bradley 1762-IA8 MicroLogix 1200 Input Module

Allen‑Bradley 1762‑IA8 – 8‑Point 120V AC Input Module for MicroLogix 1200

The Allen‑Bradley 1762‑IA8 is a digital input module designed specifically for the MicroLogix 1200 programmable controller systems. This module adds eight AC input points to your control system, allowing you to connect field devices such as limit switches, pushbuttons, and proximity sensors that operate on 100‑120V AC power. The 1762‑IA8 belongs to the Bulletin 1762 MicroLogix Expansion I/O series, which features a modular, rackless design. This design simplifies replacement and reduces spare parts inventory, ultimately maximizing cost savings for your operation.

Input Specifications and Electrical Ratings

The 1762‑IA8 provides eight digital inputs arranged in one group (inputs 0 through 7) with internally connected commons. Each input accepts a voltage range of 79 to 132 Volts AC at 47 to 63 Hertz, with a nominal rating of 120 Volts AC. The maximum on‑delay and off‑delay signal time is 20 milliseconds, which ensures responsive detection of field device status changes. Furthermore, the module has a maximum inrush current of 250 mA and draws just 50 mA from the 5V DC bus (0.25 Watts), making it energy‑efficient for your system.

Mounting and Physical Dimensions

The 1762‑IA8 offers flexible mounting options. You can install it on a standard DIN rail or mount it directly on a panel using two mounting screws. This versatility allows you to integrate the module into various enclosure configurations. The module measures 3.5 x 3.4 x 1.5 inches (89 x 86 x 38 mm) and weighs less than half a pound (0.46 lbs or 0.21 kg). Its compact footprint is ideal for space‑constrained control cabinets. For optimal performance, install the 1762‑IA8 at least six modules away from the host machine’s power supplies to minimize electrical noise interference.

System Integration and Compatibility

This input module is part of the MicroLogix 1200 expansion I/O system. You can combine digital and analog I/O modules in many configurations to match your specific application requirements. The 1762‑IA8 connects to the controller via an integrated high‑performance I/O bus, providing seamless communication and reliable data exchange. This modular approach lets you start with a basic system and expand gradually as your needs grow, reducing upfront costs and simplifying system upgrades.

Certifications and Compliance

The 1762‑IA8 meets rigorous industrial standards for safety and quality. It is C‑UL certified under CSA C22.2 No. 142, UL 508 listed, and CE compliant. These certifications ensure the module is suitable for use in North American and European markets, giving you confidence in its reliability and safety for industrial automation applications.
