EMUS CAN filter with 2x CAN

CAN filter with 2 separate CAN buses

The CAN filter is designed to connect multiple CAN bus systems together and allow only a selection of CAN messages to pass between the two CAN bus systems. This helps to keep the CAN bus systems separated and reduce bus load.

One application is linking the EMUS BMS system with external systems, transmitting only the BMS messages required by other systems. This keeps the internal BMS communication only on the dedicated BMS CAN bus, reducing bus load and the risk of interference from external CAN devices.

In addition, by using multiple CAN filters, a BMS system can be set up with multiple BMS systems in a so-called master-slave configuration.

Applications:

• Master/Slave BMS systems consisting of multiple BMS G1 control units

• CAN filter for forwarding CAN messages to external CAN bus systems

Specifications:

• Two separate (internal/external) CAN datainter interfaces

• Suitable for communication via CAN with the EMUS G1 Control Unit and external devices

• Supported CAN baud rates: 50, 125, 250, 500, 800 kbit/s and 1 Mbit/s (250 kbit/s by default)

• Firmware update via CAN interface / EMUS G1 BMS controller and control panel

• Supply voltage: 9.0 VDC to 64.0 VDC

• Reverse polarity protection: Yes

• Power consumption:

  • In active mode, at 12VDC: 24.6 mA

  • In active mode, at 24VDC: 13.0 mA

• Insulation voltage: 450V

• Transient/overvoltage protection between CAN H/CAN L and GND (and vice versa): -24V to 24V
