Product Description:
The RC2-2/20 programmable module is manufactured by Bosch Rexroth Indramat and belongs to the BODAS Controllers series. It serves as a mobile hydraulic control unit for proportional valves, pumps, and vehicle functions in industrial automation. The module combines signal conditioning, embedded computation, and communication so vehicle manufacturers can execute application-specific code, read sensors, and drive actuators within a single sealed housing.
At the core of the unit, a 20 MHz C164CI microcontroller coordinates input and output processing and task scheduling. Program storage is provided by 256 kB of flash EPROM, while transient data reside in 128 kB of RAM. An additional 2 kB of EEPROM holds calibration constants that must survive power cycles. Two analog current inputs and two analog voltage inputs allow direct connection of joysticks or pressure transducers, while two frequency inputs accept speed or flow pickups without external conditioning. Field networks are supported through one CAN interface that transmits process data at standard mobile baud rates, and diagnostics can be performed through the built-in RS-232 port. All channels are scanned under software control so deterministic loop times are maintained even when the controller is fully loaded.
A 52-pin mating connector routes power, signals, and communication lines, and the sealed connection provides IP65 protection when the gasket is correctly fitted. The power stage can supply up to 8 A of total load current, yet the module draws only 250 mA under no-load conditions, helping conserve vehicle battery capacity. Internal circuitry withstands a load-dump surge of 70 V that may occur when the alternator is disconnected. The sensor supply is maintained at 5 V ± 0.1 V, providing a stable reference for ratiometric inputs. The connector resists vibration encountered in mobile equipment, while solid-state memory retains program and calibration data without moving components.
