Product Description:
The SD301 is a compact operator terminal produced by Bosch Rexroth Indramat for the SB System Box Units series. Intended as a human-machine interface, it mounts to control cabinets and allows operators to issue commands or monitor process data directly at the machine. A monochrome LCD and resistive touchscreen combine visual feedback with fingertip input, reducing the need for external keyboards or push buttons. The localized interface provides access to parameter changes, fault acknowledgment, and production statistics without requiring a remote PC. Its compact format is suitable for automated lines that need machine-level control and clear process visualization within limited panel space.
The electronics operate from a stabilized input of 24 V DC (±20%), and the logic draws up to 150 mA at full backlight intensity. Communication with the host controller occurs over an RS-232 link that supports CTS and RTS handshake lines for buffered data exchange. The physical connection uses a 6-pin circular male plug assigned to port X6 on the system box. Screen refreshes match the graphic array’s native 320 × 240 px resolution, allowing text and bitmap symbols to appear without interpolation artifacts. The stabilized supply range accommodates moderate voltage variation while maintaining reliable operation. Buffered serial communication helps manage command and status data between the terminal and the connected controller.
The front enclosure has an IP54 rating, providing protection against airborne dust and incidental splashing. The active display area measures 5.7 inches diagonally, giving operators a clear view while keeping the panel size moderate. The enclosure has a depth of 43 mm, so it projects minimally into crowded control cabinets. A front-panel width of 210 mm supports installation in a compact cabinet opening, while the overall height is 160 mm. The monochrome display provides consistent contrast for text, status indicators, and basic graphics used in industrial control tasks. Resistive touch detection responds to pressure, allowing inputs to be registered while the operator is wearing gloves. The shallow housing also leaves more internal cabinet space available for wiring, control modules, and other mounted components.
