These protocol converters act as gateways or interfaces between CAN buses with different baud rates and protocols (SAE J1939 and/or CANopen® depending on the model). They also facilitate fast data exchange between CAN networks and an RS-422/ RS-485 bus (Modbus RTU or SAE J1587 depending on the model). These IP67 rated units have fully sealed enclosures that can withstand harsh environments.
