If you are looking for an analog output wiring diagram for the 1756-OF8 module, you have come to the right place. This module is part of the ControlLogix family of programmable logic controllers (PLCs) developed by Allen-Bradley. The 1756-OF8 module provides eight channels of analog current or voltage output, and can be used for a variety of industrial automation applications. In this article, we will discuss the wiring diagram for the 1756-OF8 module and provide some frequently asked questions (FAQs) about it.
Overview of the 1756-OF8 Module
Before we dive into the wiring diagram, let’s take a quick look at the 1756-OF8 module and its features. This module provides eight channels of analog output, which can be configured for either current or voltage operation. Each channel has a resolution of 16 bits, which translates to a range of 0-10 VDC or 0-20 mA. The module is powered by the backplane of the PLC, and requires a separate power supply if the output load exceeds 100 mA.
Current and Voltage Output Modes
The 1756-OF8 module can be configured for either current or voltage output modes. In current output mode, the module provides a variable current output to the load, while in voltage output mode, it provides a variable voltage output. The mode can be selected for each channel independently, and can be changed on-the-fly without interrupting the operation of the other channels.
16-Bit Resolution
The 1756-OF8 module has a resolution of 16 bits, which provides a range of 0-10 VDC or 0-20 mA. This high resolution allows for precise control of analog outputs, and is particularly useful in applications where accuracy is critical.

Table 1: Wiring diagram for the 1756-OF8 module.
The 1756-OF8 module is wired to the PLC backplane using a 1756-TBCH terminal block. The terminal block provides a secure and easy-to-use interface for connecting the 1756-OF8 module to the PLC. The table above shows the wiring diagram for the 1756-OF8 module. The columns in the table represent the channel, the terminal block number, the input power, and the output power. The rows in the table represent each of the eight channels on the module.
FAQs About the 1756-OF8 Module
Now that we have covered the wiring diagram for the 1756-OF8 module, let’s take a look at some frequently asked questions about this device.
Can the 1756-OF8 module be used with other PLC families?
No, the 1756-OF8 module is designed specifically for use with the ControlLogix family of PLCs. It cannot be used with other PLC families.
Can the 1756-OF8 module be used for both current and voltage output?
Yes, the 1756-OF8 module can be configured for either current or voltage output modes, and can be changed on-the-fly without interrupting the operation of the other channels.
Is a separate power supply required for the 1756-OF8 module?
A separate power supply is required for the 1756-OF8 module if the output load exceeds 100 mA. If the output load is less than 100 mA, the module can be powered by the backplane of the PLC.
What is the resolution of the 1756-OF8 module?
The 1756-OF8 module has a resolution of 16 bits, which provides a range of 0-10 VDC or 0-20 mA. This high resolution allows for precise control of analog outputs.
Can the 1756-OF8 module be used in hazardous locations?
The 1756-OF8 module is not rated for use in hazardous locations. If you require a module for use in hazardous locations, you should consult the user manual for the appropriate module for your application.
Conclusion
In this article, we have discussed the wiring diagram for the 1756-OF8 module, which provides eight channels of analog current or voltage output for industrial automation applications.
