This BA684D displays text and simple graphics in a process area. Incorporating a high contrast backlit display, push buttons and two solid state outputs, this low cost operator interface is ideal for simple process control applications.

The text display, which has RS232 and RS485 ports, supports Modbus, BEKA and legacy protocols and includes eleven standard screen formats which display up to eight variables on each screen, some with bargraphs. If custom display formats are required, these can be constructed using the free BEKA ScreenWriter software.

A powerful Pattern Matching facility is resident in the Serial Text Display which enables the capture and display of data contained in proprietary ASCII serial strings.
