This unique range of serial text displays can show simple graphics in a safe or hazardous process area. They incorporate a large, high contrast backlit display together with push buttons and two solid state outputs to offer a low cost operator interface that is ideal for simple process control applications.
The instruments, which enjoy ATEX, FM and IECEx intrinsic safety certification, communicate and are powered via a 2 or 3 wire system from a galvanic isolator in the safe area. To simplify hazardous area installations, the new dedicated BA201 galvanic isolator which has RS232 and RS485 safe area ports can power up to four BEKA intrinsically safe Serial Text Displays.
The text displays support Modbus, BEKA and legacy protocols and include nine standard screen formats which can display up to four 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 also resident in the Serial Text Display which enables the capture and display of data contained in proprietary ASCII serial strings.
The robust IP66 field mounting models have additional Ex nL (Zone 2) and ATEX dust approvals whilst the IP66 panel mounting models offer an equally robust solution.
