1762-IQ16 Allen-Bradley 24VDC Discrete Input Module

Product Overview

The 1762-IQ16 is a discrete input module from Allen-Bradley. It features sixteen 24VDC input channels. The module supports both sinking and sourcing field devices. It works with MicroLogix 1100, 1200, and 1400 controllers. The module is compact and needs minimal space. You can mount it on a DIN rail or panel. It has a single status LED for power indication. The LED helps identify problems quickly. The module uses a finger-safe cover for wiring safety. The 1762-IQ16 communicates via the 1762 bus interface. It receives 10, 24, and 30 Volts DC power.

Application Scenarios

This module expands the I/O capacity of MicroLogix PLCs. You can use up to four modules with MicroLogix 1100. Up to six modules work with MicroLogix 1200. With MicroLogix 1400, you can use up to seven modules. The module handles 24VDC signals from sensors and switches. It is suitable for dry, clean environments. The module meets Overvoltage Category II standards. Use it in non-hazardous industrial areas. The module works with sink and source field devices. Sink devices are on the negative side. Source devices are on the positive side. Source devices provide current to sink devices.
