The 1734-IV4 module is a discrete input module belonging to the Allen-Bradley POINT I/O series manufactured by Rockwell Automation. Here are some key details about this module:

Module Type: The 1734-IV4 is a 24V DC sourcing discrete input module. It allows you to connect input devices that provide a 24V DC signal, such as sensors, switches, or push buttons, to the control system.

Inputs: This module offers 4 input channels, which means it can accept signals from up to 4 devices.

Input Voltage: The 1734-IV4 module is designed to work with 24V DC input signals. It sources 24V DC to the input devices connected to its channels.

Current Load: The module is capable of sinking up to 8mA per input point.

PointBus Backplane: The 1734-IV4 module connects to the POINT I/O system through the PointBus backplane, which provides power and communication between the modules.

Terminal Block: The module features a removable terminal block that allows for easy wiring and installation of the input devices.

Configuration: The module can be configured and programmed using Rockwell Automation's RSLogix 5000 software (now known as Studio 5000). This software provides a comprehensive environment for developing, configuring, and programming the control system.

Compatibility: The 1734-IV4 module is compatible with other modules in the POINT I/O series and can be used in conjunction with them to create a distributed I/O system.
