The galvanic decoupling CRep Opto 2-channel CAN Bus repeater transmits and amplifies CAN signals transparent to the CAN protocol. CRep N allows the design of flexible wiring topologies, with star and tree structures and stub lines easily realized.
CRep Opto devices include 2 CAN segments fed to a male and a female plug of type D-Sub 9. The plugs carry the CAN signals and the supply voltage. The following table shows the function of the internally connected CAN interface.
|2||CAN_L||CAN bus line (dominant low)|
|7||CAN_H||CAN bus line (dominant high)|
|9||Vcc||Power supply +24V|
|Voltage on bus connections||-30||+30||V|
|Maximum power consumption (at 60°C)||-||2000||mW|
Any (also temporary) stress in excess of the limiting values may cause permanent damage on CRep N and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
|Current consumption (running idle)||-||30||-||mA|
|Current consumption (250kBaud, 100% busload)||-||40||-||mA|
All values, unless otherwise specified, refer to a supply voltage of 24V and an environmental temperature of 20°C.
