PCAN-Router DR – User Manual

Introduction
The PCAN-Router DR has two High-speed CAN channels. Their bit
rate is adjusted with a rotary switch on the device front. The module
forwards the message traffic bi-directionally 1:1 between both
connected CAN buses.
The ports of the device are isolated against each other and against
the power supply with at least 500 V. Furthermore, CAN 1 has a
separation voltage of up to 5 kV conforming with IEC 60601-1. With
its DIN rail casing and the support of the extended temperature
range, the module is suitable for use in an industrial environment.
Just like the PCAN-Router in the aluminum casing, the PCAN-Router
DR can be freely programmed. A corresponding development
package is included in the scope of supply.
