The SV-2800TA series CAN bus mining point intercom broadcast audio core module is a mining CAN audio transmission module used underground. This module can be used to create and utilize the CAN bus to achieve basic audio functions such as broadcasting and belt point intercom. At the same time, it can also be connected to the IP network intercom system to achieve two-way intercom, shouting, and point intercom functions with the IP phone system. In addition, the SV-2803TA series module also has functions such as Modbus TCP access, enabling connection with PLC.
