How CAN I/O Modules Fit into Modern Vehicle Networks

November 17, 2025

What is a CAN I/O Module? 

CAN I/O Module is a digital sourcing system that can be configured and customized to ensure a smooth communication between the line of network and transferring of data, while maintaining the power loads and the overall control of a system. 

How CAN Bus I/O Modules Works in Modern Vehicles

CAN I/O modules are important in supporting modern vehicle networks by enabling distributed control, smart actuation and real-time data collection across heavy-duty and off-highway platforms. We offer various types of heavy-duty vehicle electronics such as 12-output, 20-output and RTD input models. The Industrial CAN module uses a 12-pin sealed Deutsch connector (DT04-12PA equivalent). All 6 outputs on this module may be configured as a sourcing digital output or a PWM Output. This module uses J1939 Proprietary Peer-to-Peer Messaging. 

Key Advantages of CAN I/O Modules in Heavy Duty Vehicle Networks

The use of implementing CAN Bus I/O Modules into modern vehicles are beneficial:  

  • Enhancement of function and performance offers systems and subsystems in a vehicle 
  • Reduced Wiring: By enabling the ECU to ensure quick communication and simplify vehicle assembly and reduce on cost. 
  • Efficient and Robust: Prevents faulty messages and is designed to catch and correct or terminate messages with errors. 
  • Flexible and Customizable: All 6 inputs on this module may be configured as either a sourcing digital input, a 32V analog input, a 4-20mA current-reading input, a 0-5V ratio metric input, or a frequency-reading input. 

Real World Applications   

CAN Bus I/O Modules are designed for the harsh mobile equipment environment, making it a great choice for any heavy-duty application and off-highway vehicles. 

  • Heavy Duty Vehicles: Agriculture, construction, industrial 
  • Electric Vehicles 
  • Heavy-duty equipment
