The display and control unit is configured as an electronics module which consists of the actual colour TFT display module, a TFT carrier board and a plug-in keypad. The display and control unit of type Z51-AB22 is destined for installation in a station housing of the associated automation and control devices of type Z51-iST3** of the ZM51 series and for connection to a central module of type Z51-ZM22.
The display and control unit of type Z51-AB22 is designed for category I M1, protection type Ex ia I Ma as per EN 60079-0:2009, EN 60079-11:2007 and EN 50303:2000.
The unit is equipped with a colour TFT LCD display module with a diagonal of 15cm (5.7“) which offers a resolution as per VGA standard (640 (H) x 480 (V) pixels) and can show 262,144 colours. The display area of the Z51-AB22 is backlit with LEDs.
The TFT carrier board is used to connect the TFT LCD display module to the digital RGB interface of a control unit (Z51-ZM22) and to decouple its power side from the intrinsically safe circuits of this unit, as well as to scan the keypad and to transmit the information data via a serial RS232 interface to the control, plus to generate / to perform the intrinsically safe conditioning of the supply voltage for the TFT LCD module and the backlighting.
