Allen-Bradley 1734-IB4D POINT I/O Digital DC Sinking Input Module

Product Overview

The 1734-IB4D is a digital DC sinking input module from Allen-Bradley. It is part of the POINT I/O family. This module provides 4 inputs with built-in diagnostics. Each input has a status indicator for easy monitoring. The module operates at 24 Volts DC nominal. It draws a maximum of 5 milliamps per input. The compact design measures 2.2 x 0.47 x 2.97 inches. It weighs only 1.14 ounces. The enclosure is open style. You can mount it horizontally or vertically. This makes installation flexible.

Application Scenarios

Use the 1734-IB4D for industrial digital input applications. It connects to push buttons and limit switches. It also works with proximity and photoelectric sensors. The sinking input type is common in DC control systems. This module supports various network protocols. You can use it with ControlNet, DeviceNet, or EtherNet/IP. The diagnostics feature helps detect input faults quickly. The operating temperature range is -20 to 55 degrees Celsius. This makes it suitable for harsh factory floors. It is ideal for discrete manufacturing and process control.
