Product Description

For large systems, it is common to have several sensors, actuators, and binary devices working together to perform a certain industrial function or process. As the system expands, it becomes challenging to organize and keep track of all the sensors and actuators performing important functions. For this reason, B&R Automation has released digital output modules dedicated to managing digital output sources for the system. These digital output modules control actuators, sensors, and devices that need binary inputs. One example of a large digital output module is the X20cDO9322. It features 12 single-wire digital outputs that serve as sources for binary devices.

The X20cDO9322 has a rated power consumption of 0.26 watts, excluding other components. The internal I/O adds in an additional power consumption of 1.15 watts, while the actuators contribute 0.63 watts of power. The nominal voltage of the digital outputs is 24 volts, but the switching voltage may deviate from this nominal rating by -15% or +20%. In terms of the ampere rating, each digital output has a rated current value of 0.5 A. Since there are 12 digital outputs, the total nominal current is 6A, assuming all outputs are utilized. The outputs of this module are monitored with a delay of 10 milliseconds.

For this module, the X20cDO9322's channels are isolated from the bus. However, channels are not isolated from each other and from the I/O power supply. The X20cDO9322's front casing has a rated protection grade of IP 20. Depending on its orientation, the X20cDO9322's maximum temperature tolerance varies. At the default mounting orientation, it tolerates a maximum temperature of 140 degrees Fahrenheit. Meanwhile, when installed with its top face on the side, the module tolerates a maximum temperature of 122 degrees Fahrenheit.
