The I-7531 is a CAN repeater used to establish a physical coupling of two or more segments of a CAN bus system. Users can implement tree or star topologies as well as the long drop lines with the I-7531. Users can also increase the maximum number of bus nodes by using the I-7531.
The I-7531 is an optically isolated CAN repeater which provides 2500Vrms of optical isolation. This feature helps you to separate and protect critical segments of the system from the rest of the CAN network. And its galvanic protection isolates among two both CAN segments and the power supply.
The CAN connection of I-7531 is by terminal blocks. A power supply of 10VDC ~ 30VDC is required. I-7531 is housed in a rugged DIN-Rail mountable box, making it easy to install in an industrial cabinet. Futhermore, I-7531 can be used in CANopen, DeviceNet and generic ISO 11898-2 standard.
