Master Controllers
MC41
The MC41 controller is the lowest I/O count module in the MC4 family. It is best for smaller applications such as task-oriented control, implementing single features on a vehicle (valve driver for auxiliary hydraulic function), or to act as an additional controller in systems where the main controller does not provide enough I/O for the system.
MC42
The MC42 controller is an intermediate I/O count module in the MC4 family.
It is best for mid-size applications such as powertrain control (e.g. power shift transmissions), distributing I/O on a vehicle (physically placed by functions), or to act as an additional controller in systems where the main controller does not provide enough I/O for the system.
MC43
The MC43 controller is a large I/O count module in the MC4 family. It is best for bigger applications such as total vehicle control (all hydraulic functions) when it is desired to have the controller centrally located to save valuable space.
