Product Description

The X20DS4389 is a module from B & R Automation which is a part of the X20 Series of modules, and is used for digital signal processing in industrial automation systems. This module is provided with 4 digital input channels where these can accept up to 24VDC nominal voltage and has a nominal current of approximately 1.3 mA. Apart from the input channels there are 4 Programmable Digital Input/Output Channels available on X20DS4389.

Another thing that sets the X20DS4389 apart is the high-resolution timestamping capability of the device with 125ns precision. This high-resolution timestamp capability is for applications that have need of timing and synchronization such as high-speed data acquisition, motion control, and event logging. The module also incorporates edge detection with microsecond speed, thus enabling it to identify quick variations in signal states. It consists of 4 edge detection units allowing it to deal with several signal transitions in a proper manner. The module is designed to run with the internal I/O power consumption of 1.5 W. The module also has the input/output scan rate of 25 microseconds at the oversampling mode.

With respect to output functionality, the module has a maximum output voltage of 24 VDC and maximum output current of 0. 1 A per channel, and a total nominal current of 0.4 A for all the outputs. The switching thresholds are defined at below 5VDC for low signal level and above 15VDC high signal level, which is effective in different signal levels. Further, the input resistance is 18. 4 k?.

The module is equipped with a diagnostic feature that includes the use of LED status indicators and software checks to give information on the operation as well as the health status of the module. The run and error diagnostics options in this module enable the operators and technicians to monitor its operations for a continuous and efficient operation.
