Text display
ATEX, FM, IECEx BEKA

Four instruments which can display text and simple graphics in a safe or hazardous process area. Incorporating a high contrast backlit display, push buttons and solid state outputs, these are robust low cost operator interfaces that are ideal for simple process control applications.

The BEKA protocol enables text to be written anywhere on the screen in five different font sizes, together with lines, boxes, bargraphs, and simple bitmap graphics. A free programming guide and an instrument simulator package, which will run on a personal computer, may be requested from BEKA's website. The simulator demonstrates the capability of the serial text display and the attached progamming utilities enable applicational software to be developed without any additional hardware.

The recent addition of the Modbus protocol enables up to eight variables to be displayed on one of four standard screens. Apart from addressing the required text display register, no programming is required which simplifies interfacing.

All models incorporate a legacy protocol allowing replacement of MTL643/4 text displays, thus existing installations may be upgraded to include display backlighting and ATEX certification without any programming modifications
