The BODAS RC4-5 controller offers four fast and accurate Pulse Width Modulated (PWM) driver outputs with closed-loop current control. Closed-loop current control compensates for real world changes in voltage and resistance for repeatable performance from machine to machine, day-in and day-out. Adjustable parameters for solenoid current, linearization and PWM frequency adapt the controller to a variety of 12- and 24-V electro-proportional components. Software algorithms that embed knowledge of drive and control help the RC4-5 controller smoothly and accurately unleash the power of hydraulics to meet the performance demands of today’s mobile equipment.
While controlling hydraulic power is often a core requirement for mobile equipment, the RC4-5 also provides a flexible set of inputs and outputs to support a variety of work, travel, auxiliary and operator functions for system integration. Many common sensors for force, speed, pressure, position and temperature measurement may be directly connected to the controller while two CAN bus channels offer communication gateways to an array of devices including joysticks, displays and engines. The controller measures approximately 5 in. X 6 in. X 2 in., suitable for installation where space is limited.
The computational power of the controller is also a good fit for the increased features, functions, and performance specifications to compete in the evolving global mobile equipment market. With its 80 MHz, 32-bit processor, the controller can handle multiple simultaneous complex control tasks.
Software development is executed using standard C/C++ program language.
