Product Summary
The Allen-Bradley 1762-IA8 is a robust 120V AC input module for MicroLogix 1200 controllers. This unit provides eight digital inputs in a single group. Its modular, rackless design significantly reduces replacement part inventory costs. You gain reliable signal acquisition for demanding industrial environments.
Expert Technical Evaluation & Performance Review
This module delivers consistent performance for AC input sensing tasks. The 1762-IA8 operates within a voltage range of 79 to 132 Volts AC. It supports a frequency range of 47 to 63 Hertz for global compatibility. Each input offers a maximum On/Off signal delay of 20 milliseconds. This delay ensures reliable state detection for most discrete applications.
The module draws a maximum bus current of 50 mA at 5 Volts DC. This low power consumption minimizes the load on your system’s power supply. The unit also features a 250 mA maximum inrush current per point. Engineers will appreciate the integrated high-performance I/O bus architecture. This design supports efficient data transfer to the MicroLogix processor.
You must install this module six modules away from the host power supply. This distance rating helps maintain signal integrity and reduces electrical noise. The unit is C-UL certified under CSA C22.2 No. 142 standards. It also holds UL 508 listing and CE compliance marks. These certifications confirm its safety for industrial control panels.
Step-by-Step User & Installation Guide
Begin by verifying the system power is completely disconnected before installation. Mount the module horizontally on a panel using two screws. Alternatively, you can snap it directly onto a standard DIN rail. The compact dimensions are 3.5 x 3.4 x 1.5 inches for tight spaces. The unit weighs only 0.46 pounds for easy handling.
Connect the 100 to 120 Volts AC field power to the module terminals. Wire your input devices to terminals corresponding to inputs 0 through 7. Remember that all inputs share internally connected commons within one group. Ensure your circuits do not exceed Over Voltage Category II specifications. The module is intended for use in dry and clean environments only.
Secure the wiring to prevent accidental disconnection during operation. After mounting, attach the module to the MicroLogix 1200 controller via the bus connector. The rackless design allows you to assemble digital and analog modules together. You can combine various I/O types for maximum system flexibility. Power up the system and verify the input status indicators function correctly.
