SAE J2057/2 – Class A Multiplexing Actuators (Stabilized: Dec 2022)

The Class A Task Force of the Vehicle Network for Multiplex and Data Communications Committee is publishing this SAE Information Report to provide insight into Class A Multiplexing. Multiplexed actuators are generally defined as devices which accept information from the multiplexed bus. A multiplexed actuator can be an output device controlled by the operator or an intelligent controller. A Multiplex actuator can also be a display device that reports the status of a monitored vehicle function. This document is intended to help the network system engineers and is meant to stimulate the design thought process.

A list of multiplexed actuator examples is provided in Appendix A Figure A1. Many other examples can be it identified.
