Product Description:
The 4B1270.00-K09 text panel is built by B & R Automation for the 4B1 PanelWare Panels series. It combines a liquid crystal display with a sealed keypad so production personnel can view machine status, enter setpoints, and acknowledge alarms directly from the cabinet door. The compact form supports installation in confined control enclosures where only limited space is available for an operator interface. Its integrated controls provide direct access to essential machine functions without requiring a separate keyboard or display.
Power is supplied at 24 VDC, a control voltage common to many PLC enclosures, so an additional voltage converter is unnecessary. The liquid crystal screen presents process messages in a 4 × 20-character format, providing four rows with 20 characters per row. A rated luminance of 200 cd/m² helps maintain readability under typical factory lighting. Operators can adjust the contrast through the front-panel keys, while the liquid crystal technology keeps power consumption low. Communication uses a 9-pin male D-Sub connector that is electrically isolated, helping protect the logic circuits from bus transients. The connector uses pin 2 for L, pin 3 for ground, and pin 7 for H, allowing the communication cable to be wired correctly. The assembly tolerates noncondensing humidity, reducing the risk of moisture forming on the display surface during normal operation.
The node address and baud rate are selected with hex switches, eliminating the need for software tools during setup. A dual-color backlight that glows yellow or green supports color-coded operator prompts, and the CAN interface carries diagnostic traffic alongside other modules on the same network. User input is provided through a membrane keypad that resists oil and dust, helping protect the switches in industrial assembly areas. For power wiring, a 3-pin terminal block accepts conductors ranging from 0.5 to 2.5 mm². Captive screws secure the conductors and help prevent the connections from loosening under vibration.
