Eaton mRFRM Multiplexed Rearfed Fuse and Relay Module

32 outputs, 14 relays   28 Fuses, High Power, Rugged, Flexible.

mRFRM J1939 CAN Configuration & Monitoring
The Eaton mRFRM communicates with other devices on the vehicle’s CAN bus using the SAE J1939 protocol and can be part of a multiplexing system that eliminates the need for individual connections between switches and loads. The mRFRM works by receiving messages to turn its relays “on” and “off”, and by sending messages indicating the state of its monitored components.
