Penerangan

Product Overview

The Allen-Bradley 1762-IR4 is a MicroLogix RTD and resistance input module with 4 channels. Weighing approximately 230 g, it interfaces Resistance Temperature Detectors and resistance generating devices for temperature, displacement, and position monitoring in industrial applications.

Key Features

4 channel RTD and resistance input with Sigma Delta conversion. Compatible with 2 wire, 3 wire, and 4 wire RTDs. Accepts resistance ranges of 0 to 150 ohm, 0 to 500 ohm, 0 to 1000 ohm, and 0 to 3000 ohm. Selectable input filters at 10 Hz, 50 Hz, 60 Hz, 250 Hz, 500 Hz, and 1 kHz. Auto calibration on channel enable or programmable every 5 minutes. Single diagnostic LED for status and power indication. Lightweight 230 g design with finger safe cover for input terminal blocks.

Installation Guide

Mount the 1762-IR4 (approx. 230 g) on a DIN rail or panel in a non hazardous, dry, and clean environment away from electrical noise and heat. Wire RTDs using 2 wire, 3 wire, or 4 wire configuration as required. Connect resistance devices using 2 wire or 3 wire. Configure each channel after installation since operation details are channel specific. Use the finger safe cover when wiring input terminal blocks. Module update time increases with more channels and autocalibration cycles.

Engineering Advantages

Supports a wide range of RTD types for application flexibility. Selectable input filters reduce noise for accurate temperature measurement. Auto calibration maintains accuracy over time without manual intervention. Lightweight 230 g design requires minimal mounting space. Module and channel diagnostics simplify troubleshooting. Compatible with MicroLogix 1100, 1200, and 1400 controllers for seamless expansion.
