The patented MicroPlex is the smallest CAN controller with the highest integration level from MRS Electronic. This module has a footprint of 2 Micro 280 relays so you can easily build your own CAN bus capable power distribution systems. The 7H version has a total of 7 high-side driver outputs that switch the supply voltage. Of these, 6 are PWM-capable. In this way, the innovative MicroPlex adapts perfectly to your needs.

The MicroPlex can very quickly and easily generate an intelligent system with CAN bus communication from previously simple ISO 280 boxes. With the CAN interface, the Microplex allows you to upgrade your existing systems with diagnostic capability.
