1746-IA16 Allen Bradley Digital AC Input Module

description

The Allen-Bradley 1746-IA16 is a robust and essential AC input module designed specifically for the SLC 500 programmable logic controller (PLC) platform. This module provides 16 individual inputs for sensing the on/off status of a wide variety of 120V AC field devices.

A key feature of the 1746-IA16 is its optical isolation, which electrically separates the field wiring from the sensitive PLC backplane. This isolation protects the control system from electrical noise, voltage spikes, and ground loops, ensuring reliable operation and enhanced system longevity. Each input is equipped with an LED status indicator, allowing for quick visual verification of input status, significantly aiding in troubleshooting and maintenance.

Feature

Optically Isolated: Ensures electrical separation between the field wiring and the SLC 500 processor, protecting sensitive control circuitry from voltage spikes and noise

Direct Connection: Designed for direct connection to 120V AC input devices, simplifying wiring and reducing the need for external components.

LED Status Indicators: Each input has an individual LED indicator, allowing for quick visual confirmation of input status and aiding in troubleshooting.

Removable Terminal Block: Features a removable terminal block for easy wiring and maintenance, streamlining installation and reducing downtime.

APPLICATION

Machine Control: Ideal for monitoring the status of AC-powered limit switches, pushbuttons, indicator lights, and motor starter feedback in various machinery, from packaging lines to material handling equipment.

Process Monitoring: Used in process control systems to sense the on/off status of AC-powered pumps, valves, fans, and alarms, providing critical feedback to the PLC for process management.

Motor Control Centers (MCCs): Integrates within MCCs to monitor the operational status of motor control circuits, including contactor auxiliary contacts and thermal overload indicators.
