Overview
The Allen-Bradley 1762-IQ16 is a MicroLogix 16-point digital input module from Rockwell Automation. It is a 16-point, 24 V DC sink/source input module designed for the MicroLogix 1200 family of controllers. The 1762-IQ16 is a 24V DC input module developed by Allen Bradley for the MicroLogix 1200 series. The module offers compact form-factor expansion for discrete sensor inputs and includes individual channel LEDs for quick diagnostics.
Key Features
- This module accommodates 16 individual inputs that provide flexibility for various input configurations.
- It is a Sink/Source Input Module.
- The 1762-IQ16 has an IP20 rated Enclosure.
- It offers reliable digital input connectivity in a compact form, with status indication via LEDs, DIN-rail or panel mounting, and robust electrical specifications suited to industrial use.
- Signal performance is managed with a maximum delay of 8 milliseconds applicable to both on and off signal states.
Technical Specifications
The 1762-IQ16 delivers fast response and flexible wiring for diverse automation applications:
- It is engineered to operate at a voltage category of 24 volts DC, with an operational voltage varying from 10 to 30 volts DC.
- Amperage: 12 mA
- The capability to draw a maximum bus current of 70 mA at 5 volts DC allows for efficient power allocation to the system.
- The input module possesses a nominal impedance of 3K ohms, ensuring compatibility with various sensor inputs.
- The design includes specifications for off-state response, with a maximum off-state voltage rated at 5 volts DC and a maximum off-state current limit of 1.5 mA.
- To activate the inputs, a minimum on-state voltage of 10 volts DC is necessitated.
- Temperature Rating: 149 degrees F (65°C)
Typical Applications
This module serves as the “sensor front end” of your automation system — connecting binary signals (limit switches, proximity sensors, push-buttons) into controller logic. These input channels are ideal for interfacing field devices such as limit switches, relay and magnetic contactor contacts, proximity sensors and other discrete devices. The module is widely used in packaging, material handling, process control, and general discrete automation systems where multiple sensor inputs must be monitored and fed to a PLC for decision-making logic.
