What Is the 1746 OB32 Module?
The 1746 OB32 is a digital output module that is part of the Allen-Bradley SLC 500 series. It has 32 outputs, and each output can be individually controlled. The module is designed to work with a range of voltages, from 5V DC to 220V AC. It can be used to control a range of devices, including motors, lights, and solenoids.
The 1746 OB32 has a compact design and is easy to install. It can be mounted on a DIN rail or panel, and has a removable terminal block that makes wiring a breeze. The module is also programmable, which means you can customize the output signals to meet your specific needs.
Wiring Diagram for the 1746 OB32
The wiring diagram for the 1746 OB32 can be a bit confusing, especially if you’re not familiar with digital output modules. However, once you understand the basics, it should be easy to figure out. The wiring diagram is divided into three main sections: power, input, and output.
Power Section
The power section of the wiring diagram is where you connect the power supply. The 1746 OB32 requires a power supply of 5V DC to 220V AC, depending on the voltage of your device. There are two terminals in the power section: +V and -V. You need to connect the positive lead of your power supply to the +V terminal, and the negative lead to the -V terminal.
Input Section
The input section of the wiring diagram is where you connect the control signals. The 1746 OB32 has 32 inputs, each of which can be controlled individually. The inputs are divided into four groups of eight, labeled I0-I7, I8-I15, I16-I23, and I24-I31. Each group has its own common terminal, labeled C0-C3.
To connect your control signals, you need to connect the positive lead of your device to the appropriate input terminal, and the negative lead to the corresponding common terminal. For example, if you want to control a motor with output 1, you would connect the positive lead of the motor to input terminal I0, and the negative lead of the motor to common terminal C0.
Output Section
The output section of the wiring diagram is where you connect the devices you want to control. The 1746 OB32 has 32 outputs, each of which can be controlled individually. The outputs are divided into four groups of eight, labeled O0-O7, O8-O15, O16-O23, and O24-O31. Each group has its own common terminal, labeled C0-C3.
To connect your devices, you need to connect the positive lead of each device to the appropriate output terminal, and the negative lead of the device to the corresponding common terminal. For example, if you want to control a light with output 1, you would connect the positive lead of the light to output terminal O0, and the negative lead of the light to common terminal C0.
