Electric Drives and Controls Hydraulics Linear Motion and Assembly Technologies Pneumatics Service Analog Amplifier Rexroth RA: Easy, user-friendly control of pumps and valves The Drive & Control Company
The effective solution: actuate pumps and valves reliably and easily without programming The analog amplifier RA from Rexroth amplifies and regulates control signals from joysticks, sensors or potentiometers to ensure the effective, reliable actuation of pumps and valves. At the same time, the new Rexroth RA offers many decisive advantages: it saves the vehicle manufacturer enormous costs thanks to its easy assembly and rapid configuration. Vehicle users benefit too: it ensures controlled machine movement and a safe, comfortable ride thanks to its smooth actuation. The Rexroth analog amplifier further enhances the safe and reliable functioning of working machines, as the operating function goes into automatic fail-safe in case of damaged cables. In this way, the Rexroth RA is more than just an amplifier. It is a mediator that promises comfort. Joystick Pumps Rexroth RA Sensor Valves The analog amplifier Rexroth RA amplifies and regulates control signals from joysticks, sensors, potentiometers or industrial controls (SPC) to ensure the effective, reliable actuation of pumps and valves. Smooth transitions, individually and easily adjustable The new RA regulates control commands so that the vehicle changes its movement and direction less jerkily and much more smoothly and gently. This ensures considerably safer work for the user, when standing on an aerial work platform, for example. The four ramping functions, which enable smooth transitions even when abrupt signal changes are received, can be preset individually and easily. Safety when cables break Even in the event of a broken cable at the input, the response characteristic of the RA is clearly defined. With the corresponding installation the RA automatically brings the output signals into a safe operating state, thereby preventing damage to the machine. Moreover, a red fault diode warns the operator of the cable break.
Wire up adjust ready! In a very short time, the vehicle builder can install the RA and configure it with a screwdriver via potentiometers on the top of the housing. This saves a great deal of time. What s more, he has no need for configuration tools as with digital control units, for example neither does he require an electronics expert or programmer to set the potentiometers. This saves considerable costs. Open for more input mediator for two actuators With just one device, you can actuate two proportional valves, for example. And the Rexroth RA analog amplifier is flexible for numerous circuitry variations. Housing features: Sturdy and proven Bosch housing (IP 65), Four status LED s, Two mounting points 25-pin AMP-connector Easy configuration possible via potentiometers on top of the housing Technical features: Power supply 9 32 V One or two proportional outputs up to 2.3 A Independent adjustment of min./max. current per channel, and up/down ramp per channel Short-circuit-proof outputs Inputs with short-circuit detection Temperature range 40 to +85 C EMC stability 100 V/m
From RA to BODAS the unique complete system for the electronic control of mobile equipment Rexroth RA is the reliable, cost efficient, user-friendly solution for simple actuation systems. If you require more complex tasks for the control of your mobile work machines, Rexroth BODAS opens the door to the solution to suit your requirements. With its logically consistent, scalable modular architecture, BODAS provides a complete hardware and software solution, which saves a great deal of development time. With its open, flexible software modules, this solution can be adapted easily and individually in line with more demanding requirements. Rexroth has developed electronic components and systems for a wide range of requirements, and these are precisely coordinated with our hydraulic valve and transmission technology. As a result of the close cooperation between Rexroth and Bosch in development, testing and production, BODAS is ideally suited for use in mobile equipment. Rexroth s performance spectrum in the field of electronics extends far beyond a controller and sensors: it includes development and diagnostic software and additional tools, not to mention complete commissioning instructions and software descriptions. With the BODAS design graphic programming interface, you can design, simulate and debug the software for your machine by yourself, and then transfer it to the controller. Whatever your intention RA, BODAS or a customized system: With Rexroth s comprehensive and unique expertise in applications, development and production you can create the right solution for any electronic control of mobile equipment.
