To maximize hydraulic-component and overall system performance, the Bodas RC4-5 controller is powered by a 80-MHz, 32-bit TriCore chip that combines computational power with flexible inputs and outputs in a shielded aluminum package. Four fast and accurate PWM driver outputs with closed-loop current control compensate for changes in voltage and resistance. Adjustable parameters for solenoid current, linearization, and PWM frequency let the controller adapt to a variety of 12 and 24-V electroproportional components.
The RC4-5’s inputs and outputs support a variety of functions for system integration. Many force, speed, pressure, position, and temperature sensors may be connected to the controller. Two CANbus channels offer communication gateways to an array of devices including joysticks, displays, and engines. The BODAS-service tool lets controllers be Flash programmed, configured, optimized, diagnosed, and data logged.
