The Opus A3F and A3S Wachendorff display units are cost-efficient, rugged operator control panels for use on heavy-duty vehicles and work machines that must operate outdoors in harsh conditions. They are fully equipped with an encoder, three hard and eight soft-function keys, integrated buzzer, RS232 and USB ports, and CAN bus. The A3F (full-featured) unit has analog/digital inputs, digital outputs, Ethernet and video connections for use with a camera to monitor process operations.
Display: Sunshine-readable thin film transistor (TFT) color graphic LCD.
480 x 272 pixel resolution, viewing angle ± 50°, 4.3 inch (109 mm) diagonal
