Product Description
The PanelView 550 (2711-T5A5L1) is a compact 24VDC-powered HMI terminal with DH485 communication, featuring a monochrome touchscreen display for industrial process operation. It has 112KB to 240KB of internal memory (depending on series) expandable via ATA memory cards (256KB-32MB). Its capabilities can be enhanced with accessories like anti-glare overlays and communication modules. The terminal supports various runtime objects and offers internal configuration settings for parameters like language and video. It operates on 18-32VDC (24VDC nominal), consuming a maximum of 18W. Weighing 0.93kg (1.48lbs) and measuring 152x185x82mm (6.0x7.28x3.20in), it functions reliably between 0-55C (32-131F) with 5-95% noncondensing humidity, and can withstand 30g shock and 2g vibration. Storage temperature ranges from -20 to 85C (-4 to 185F).
Is Your Device Showing These Signs?
The Allen Bradley 2711-T5A5L1 HMI commonly experiences failures related to the touchscreen, backlight, and power supply. Touchscreen unresponsiveness or inaccurate calibration necessitates replacement. Dim or non-existent displays are attributed to a failing backlight inverter or the backlight itself, requiring repair or component replacement. Power supply issues manifest as intermittent operation or complete failure, often due to capacitor degradation or component failure on the power board; address this through repair or replacement of the power supply unit. Communication problems via the serial port or Ethernet port also occur, investigate cabling, port configuration, and potentially replace the communication board.
