Product Overview

The M460 is a high performance electronics module that is suited to applications requiring a large number of input/outputs. The chassis mounting, sealed metal housing meets defence specifications and IP68 environmental protection standards.

Based on the Freescale MPC5534 32-bit microcontroller, the M460 features 2 CAN interfaces and 53 standard input/output functions via two 40-way connectors. The precision analogue functions include direct support for RTD sensors and thermocouples, while the configurable high current switching outputs support injector, spark and PWM drives.

Typical applications include; diesel after-treatment control, transmission control and complex ancillary vehicle functions.

Build Options

At additional cost it is possible to build options that will modify the hardware specification within certain limits.

Custom Variations

Pi Innovo engineering services can rapidly develop custom ECUs based on the resusable block designs within OpenECU.
