product details
The Allen-Bradley 1769-OF4VI Individually Isolated Analog Current Output Module is a solid-state electronic module designed and manufactured to provide 4 independent and differential voltage outputs that are isolated from one another and that can be individually customized according to the final users' application needs. Each one of the 4 independent outputs can receive different voltage ranges, such as 0 to 10 Volts DC, 0 to 5 Volts DC, and 1 to 5 Volts DC. The Allen-Bradley 1769-OF4VI Individually Isolated Analog Current Output Module can be connected to a maximum current output of 5 milliamps with a load range output resistance rating of higher than or equal to 2 kiloohms. The capacitive load for the voltage outputs can be a maximum of 1 microfarad.
The Allen-Bradley 1769-OF4VI Individually Isolated Analog Current Output Module does not need any field calibration because it works in a "plug-and-play" fashion. The final users only need to connect the analog voltage circuits to their corresponding output points and the device will automatically detect the voltage range that those circuits are working with. The accuracy rating of this module is about 0.5% full scale at 25 degrees Celsius (77 degrees Fahrenheit). Open circuit and short circuit protection capabilities are provided with this module. The Allen-Bradley 1769-OF4VI Individually Isolated Analog Current Output Module is suitable for both panel mounting and DIN rail mounting, and generates a very low amount of heat (about 2 Watts). The environmental protection level provided for the module is very low (IP 20), so the manufacturer recommends choosing a humidity-controlled space for the installation of the device.
