OVERVIEW

Introducing M25O

The M250 module is a compact electronics module that is suited to computationally intensive applications requiring a chassis mounted, sealed metal housing with IP67 environmental protection. Based on the same Freescale MPC5534 32-bit microcontroller as the M460, the M250 features 2 CAN interfaces, precision analogue 12-bit inputs and configurable high current switching outputs. A group of inputs and outputs are particularly suited emissions control applications with appropriate sensor signal conditioning and drive characteristics.

NOTE: Not recommended for new designs.

APPLICATIONS

M250 Applications Include:

Application Description
Diesel exhaust after-treatment M250 is suited for basic aftertreatment systems that utilize a combination of Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) to control carbon monoxide and particulate matter.
Electric Vehicle Control M250 can be used for electric vehicle supervisory control development interacting with battery, inverter, motor drive and other vehicle systems to provide drive control, torque management, for electric vehicles
Active Damping Control System Enhanced safety, stability and ride control can be achieved with active damping control system with the M250
Aerodynamic actuator control M250 can be used for an active aerodynamic control system for rear spoiler deployment and vehicle ride height adjustment to provide increased traction and stability at high-speed without significantly increasing aerodynamic drag or adversely affecting low-speed ride and handling qualities.
