Allen-Bradley module 1769-IQ16 is a digital input module from the CompactLogix series of programmable logic controllers (PLCs). It is designed to interface with 16 discrete input signals. 

Here are some key features of the 1769-IQ16 module:

1. Input Type: The module supports 16 discrete input points. These inputs can be configured for either sinking or sourcing input types based on the application requirements.

2. Input Voltage Range: The module supports a wide range of input voltages, typically from 10V DC to 30V DC.

3. Input Filtering: The module provides built-in noise filtering to improve the stability and reliability of the input signals.

4. LED Status Indicators: There are status indicators for each input channel, allowing you to easily monitor the state of the input signals.

5. Removable Terminal Block: The module is equipped with a removable terminal block that makes wiring and maintenance tasks convenient.

6. Compact Design: The 1769-IQ16 module is designed to fit into
