ECU-0408A

General Purpose Machine Controller for Off-Highway, Mobile Equipment

Overview

Description

The ECU-0408A is a fully programmable control unit featuring 15 flexible I/O pins: 4 PWM outputs and up to 11 configurable inputs of analog, digital or frequency (see table). All outputs are capable of driving up to 3 amps, and 3 one amp current feedbacks are available for closed-loop operation. It features a 100 MHz 16/32 bit processor, and has the ability to communicate using CAN Open communication protocol.

NOTE: Refer to Input/Output table below for pin configuration capability. Refer to ECU-0408A Technical Reference Manual for specific data and ratings of individual inputs and outputs.
