The MACH-HYDRA is an electronic control unit designed to operate up to 20 proportional hydraulic valves.
It supports both voltage and current control modes, allowing precise adjustment of valve positions. The controller communicates over the CAN/CAN FD bus (SAE J1939 protocol), and selected valve outputs can also be driven via external voltage or current loop inputs.
The hydraulic solenoids can be connected either in low-side or high-side, extending the flexibility of electrical wiring.
