Product Summary
The Allen-Bradley 1762-IA8 provides eight discrete AC inputs for MicroLogix 1200 controllers. It handles 100-120V AC signals with a maximum on/off delay of 20 ms. This robust module features a rackless design and weighs only 0.46 pounds. Its compact dimensions (3.5 x 3.4 x 1.5 inches) simplify panel integration.
Product Procurement & Buyer Guide
Procurement managers need a reliable, cost-effective I/O solution. The 1762-IA8 delivers exactly that. Its modular, rackless construction slashes spare parts inventory. You can combine digital and analog modules freely. This flexibility reduces total ownership costs for your automation line.
The module offers a voltage category of 100 to 120 Volts AC. Its operating range extends from 79 to 132V AC at 47-63 Hz. This wide tolerance ensures stable operation even in fluctuating line conditions. The unit draws only 50 mA at 5V DC from the backplane.
For system planning, note the power supply distance rating of 6. This means you can install the module up to six slots away from the host power supply. Such spacing simplifies cabinet layout and thermal management. The module mounts either horizontally or on a standard DIN rail.
Compatibility is broad. The 1762-IA8 works with MicroLogix 1100, 1200, and 1400 controllers. This commonality simplifies multi-platform upgrades. Engineers can standardize on one input module across different machine families.
Expert Technical Evaluation & Performance Review
From an engineering perspective, the 1762-IA8 delivers solid performance for AC sensing applications. Each of the eight inputs shares a common group (inputs 0-7). The maximum inrush current per input is 250 mA. This handles brief spikes from motor starters or contactor coils.
Signal response time is a key metric. The module guarantees a maximum on/off delay of 20 milliseconds. For most industrial discrete sensing tasks, this speed is adequate. It supports typical limit switches, pushbuttons, and proximity sensors.
The module requires clean, dry environments. It only uses circuits within Over Voltage Category II. This limits its exposure to transient surges. We recommend installing transient suppressors on heavily inductive loads.
Installation guidelines are clear. Keep the module six modules away from the host’s power supplies. This spacing minimizes electrical noise coupling. The integrated high-performance I/O bus ensures reliable data transfer back to the controller.
