The PCAN-TJA1054 bus converter establishes a connection between a high-speed CAN bus (ISO 11898-2) and a low-speed CAN bus (ISO 11898-3). One of the most important potential applications of the bus converter is a simple connection between a PCAN series CAN interface (e.g. PCAN-USB) and a low-speed CAN bus.

Specifications

• Adapter from high-speed CAN to low-speed CAN
• Bit rates of up to 125 kbit/s
• CAN transceiver NXP PCA82C251 and TJA1054
• Termination resistors for low-speed CAN can be switched (560 Ohm / 5.66 kOhm)
• Power LED
• Error LED (low-speed CAN)
• CAN bus connection via D-Sub, 9-pin (in accordance with CiA® 102)
• Power supply (5 V) through pin 1 of the high-speed CAN connection. All PEAK CAN cards can be set to the required supply via solder jumper
