ESD CAN-Repeater Passive I- and Y-Repeater
This ESD CAN-Repeater connects multiple CAN devices to a network and ensures that the data packets reach their recipients without errors. This is achieved by amplifying and retransmitting the signals on the CAN bus. The repeater increases the range of the CAN bus and allows for the connection of additional devices.
The CAN-Repeater is a passive device, which means that it does not require an external power supply. It is powered by the CAN bus itself. The repeater is also galvanically isolated, which means that it does not conduct electrical current between the CAN bus and the power supply. This isolation protects the CAN bus from electrical interference and noise.

ESD CAN-Repeater Passive I- and Y-Repeater Owner's manual

ESD CAN-Repeater Passive I- and Y-Repeater
This ESD CAN-Repeater connects multiple CAN devices to a network and ensures that the data packets reach their recipients without errors. This is achieved by amplifying and retransmitting the signals on the CAN bus. The repeater increases the range of the CAN bus and allows for the connection of additional devices.
The CAN-Repeater is a passive device, which means that it does not require an external power supply. It is powered by the CAN bus itself. The repeater is also galvanically isolated, which means that it does not conduct electrical current between the CAN bus and the power supply. This isolation protects the CAN bus from electrical interference and noise.
