Gauges
4 Sonceboz stepper motor driven gauges
Truck/Bus Cluster
H4A
OEM instrument cluster with 4 stepper motor gauges, monochrome display, CAN J1939 support, multiple digital/analog inputs, USB bootloader updates, warning buzzer, and water/dust protection
Overview
Overview of the H4A
The H4A instrument cluster puts primary vehicle data on analogue dials and supporting data on the central digital screen. Drivers can read speed, RPM, fuel, or temperature at a glance, then use the 5-inch EBN panel for warnings, menus, and diagnostics. Warning management and monitoring options are built to raise driver awareness on heavy equipment. The cluster is a rugged heavy duty instrument cluster designed for industrial and off-highway duty, with CAN 2.0B / J1939 linking it to the vehicle ECUs.
