Product Description
The Allen-Bradley 2706-B21J16 Dataliner module features a 14.4 x 14.4 inch vacuum fluorescent display (VFD) showing two lines of 16 characters each, operates on 120V AC, and includes 16 KB of RAM and a parallel port. It functions as a slave device displaying ASCII text from a controller, and is housed in a Type 12/13/14 enclosure. To prevent damage from electrical arcing, disconnect power before connecting or disconnecting cables. It withstands operating temperatures of 0-60C, storage temperatures of -40-85C (with 5-95% non-condensing humidity), and meets EN 50081-2 EMC standards for industrial environments, with operating and non-operating shock ratings of 30g and 50g respectively.
Is Your Device Showing These Signs?
The Allen Bradley 2706-B21J16 HMI commonly experiences issues related to backlight failure, requiring LCD replacement or inverter board repair. Touchscreen unresponsiveness stems from damaged overlays or controller board malfunctions, necessitating calibration or component-level repair. Communication errors with PLCs are traced to corrupted firmware, faulty serial/Ethernet ports, or incorrect communication protocol settings; firmware upgrades or port replacements resolve these issues. Power supply failures manifest as intermittent operation or complete shutdown, demanding capacitor replacement or power module repair. Memory corruption leads to application errors or boot failures, fixed by memory module replacement or firmware reflashing.
