X20DC1396
The X20DC1396 by B & R Automation is a versatile digital counter module designed for use with ABR incremental encoders and an enable switch. This module functions as a digital signal processor within X20 systems, offering robust status indicators to monitor states, errors, and I/O function results. Operating at a standard supply voltage of 24 VDC, the encoder input draws up to 600 mA and supports frequencies up to 100 kHz, utilizing a 16/32-bit counter for precise evaluations. Its digital input consumes approximately 3.3 mA and provides a 3-wire connection with a resistance of 7.19 kOhms. The module supports installation at altitudes up to 2000 meters and is rated IP 20 for protection. It accommodates both horizontal and vertical orientations, though spacing from adjacent modules should be considered. Notably, the ABR incremental encoder features integrated protective devices for its supply voltage, while the reference enable switch is isolated from the bus but not the encoder.
