FEATURES:
• Advanced electronic design for reliability and accuracy.
• Reliable operation in real-world temperature conditions from
–40°C to +70°C (–40°F to +158°F).
• Fully-sealed, compact cast-aluminum housing.
• Inputs and outputs are
protected against shorts.
• Outputs have diagnostic capability.
• No external cooling or heat dissipation required.
• Software developed with
CoDeSys 2.3 Programming Tool.
  DESCRIPTION:
The ECU-2820 Machine Controller is a general-purpose programmable controller designed to withstand the real-world environmental demands of the off-highway mobile market. The ECU-2820 can be used as a stand-alone controller, or for integrating into a CAN network with other devices.

Input configuration can be set for up to 52 inputs consisting of Digital, Pulse, Current
Measuring Feedback and Analog inputs. Output configuration can be set for a total
of 28 outputs consisting of up to 24 PWM or digital high-side drivers, and up to 4 digital low side drivers. All outputs are capable of driving up to 3.0 Amps.

NOTE: Refer to Input/Output table below for pin configuration capability.
Refer to ECU-2820 Technical Reference Manual for specific data and ratings of individual inputs and outputs.
