BITBUS Controller M-module – M304

The M304 BITBUS Controller M-module, featuring the i8044 BITBUS enhanced microprocessor provides all necessary functions to implement a BITBUS master or slave node. The resident firmware includes an extensive Remote Access and Control (RAC) command set, to allow specific functions to be performed on the remote nodes.
The BITBUS allows up to 250 nodes to be easily interconnected over a physically distributed domain. Distribution capability ranges from 30 to thousands of meters.
The different modes of operation are optimized for a wide range of applications covering the spectrum from high speed servo motor control in robotics, to long distance environmental control.
