1734-OB8 Allen Bradley IO Modules

1734-OB8 Allen Bradley IO Modules are one of the many different Input/Output (I/O) modules available from Allen Bradley. They offer reliable and efficient performance in a wide range of industrial applications, including motion control, machine automation, and process control. In this blog post, we’ll take an in-depth look at these I/O modules, their features and specifications, and how they can be used to improve productivity and performance for your business.

Description of the 1734-OB8 Allen Bradley IO Modules

The Allen Bradley 1734-OB8 is an IO module that is used for input and output operations. It has 8 input channels and 8 output channels. The module is used in applications where there is a need for high-density input and output capability. The module supports various types of I/O including digital, analog, and specialty I/O.

Specifications of the 1734-OB8 Allen Bradley IO Modules

The 1734-OB8 Allen Bradley IO Modules offer eight (8) channels of analog input and output with a 16-bit resolution. The module has an input range of 0 to 10 volts DC and an output range of 0 to 10 volts DC. It can be used with any Allen Bradley PLC that has an available slot for it.

Installation of the 1734-OB8 Allen Bradley IO Modules

The Allen Bradley 1734-OB8 is an 8-channel analog input module that can be used to measure a variety of process variables, including temperature, pressure, and flow. This module provides eight channels of isolated inputs with 12-bit resolution and a maximum sample rate of 10 Hz. It can be used with a variety of Allen Bradley PLCs, including the MicroLogix 1000 and 1100.

To install the 1734-OB8, first remove the cover from the PLC chassis. Next, insert the module into an empty slot in the backplane. Make sure that the module is fully inserted and that the locking tab is engaged. Finally, replace the cover on the PLC chassis and tighten the screws to secure it in place.

Once the module is installed, it must be configured using software before it can be used. The configuration process will vary depending on which PLC is being used, but typically involves setting up the I/O address map and determining which channels will be used for what purpose. After the module is configured, it can be connected to any field devices that need to be monitored.

Configuration of the 1734-OB8 Allen Bradley IO Modules

The 1734-OB8Allen Bradley IO Modules can be configured in a variety of ways to suit the needs of your application. The most common configuration is to have the module configured as an input module, with eight inputs. However, the module can also be configured as an output module, with eight outputs. Additionally, the module can be configured as a mix of inputs and outputs, with four inputs and four outputs.

When configuring the 1734-OB8 Allen Bradley IO Module, it is important to consider the type of input or output that you will be using. For example, if you are using digital inputs, you will need to configure the module accordingly. If you are using analog inputs, you will need to configure the module differently. Additionally, if you are using both digital and analog inputs or outputs, you will need to configure the module appropriately for each type.

Once you have determined the appropriate configuration for your application, you can then begin configuring the 1734-OB8 Allen Bradley IO Module. To do this, you will need to use either the Configuration Software or RSLinx Classic software. Once you have launched either of these software applications, you can then follow the on-screen instructions to configure themodule for your specific application.

Operation of the 1734-OB8 Allen Bradley IO Modules

The 1734-OB8 Allen Bradley IO Module is a 8-channel digital input module that can be used with a Programmable Logic Controller (PLC) to provide input signals for various applications. The channels on the module can be configured for different functions, such as momentary contact, latching, or pulsed inputs. The module also has an LED indicator for each channel that shows the status of the input signal.
