  • B-Versions o Store up to 255 texts o Variable data insert o Multiple character sets o BCD, Binary or Serial text call o Built-in real-time clock o Alarm relay
  • A-Versions o ‘Slave’ displays o RS-232C interface range of intelligent message displays designed to show operator information in many types of industrial control and autom ation systems. The bright green fluorescent displays are easy-to-read in most operating environments. The wide choice of character sets, including Cyrillic, caters for the special characters that are required by many European and international users. B-Versions have a built-in text memory to store up to 255 texts. These can be triggered by a parallel or serial interface, either as static texts, in one or two lines with 20 or 40 characters per line (depending on the model), or up to 175 characters as scrolling text. In addition, variable data can be input via the serial or parallel interfaces and overla id in selected pre-stored messages. Up to three blocks of variable data can be included in a single text. Texts can also be pre-tagged to operate the built-in alarm relay when they are triggered. Texts are programmed in ‘edit’ mode, or by ‘file’ transfer via the seri al interface. Programming software and P.C. connection cables are available. Four display modes are available. In the first mode, the currently triggered text message is displayed and the operator can call an optional linked message, e.g. a ‘help’ text. The other three modes build up a display queue. This can be set to sh ow the first, the last, or all messages in sequence for a preset time. The operator can page through, read and delete messages in the queue by using the press-button keys on the front of the uni t. Four control inputs allow remote operation of the display modes. A serial data output is available to send pre-tagged messages to a printer, comp lete with date & time from the internal real-time clock, or to a DAA … A version ‘slave’ display. A-Versions are designed to be ‘slave’ displays or ‘visual printers’. They do not have a text memory. Data is input through the serial interface and the same wide range of character sets is available. Both A- and B-Versions are available in a choice of sizes, with either one or two line displays: Model Bezel Size (mm) No. Lines Characters/Line Text Memory Power Supply DAA 144-120 A 144 x 36 1 20 --- DAA 144-120 B 144 x 36 1 20 YES 24VDC DAA 288-240 A 288 x 72 2 40 --- DAA 288-240 B 288 x 72 2 40 YES 115VAC, 230VAC or 24VDC Specifications A-Versions General Serial interface RS-232C, 110…2400 baud, 7 or 8- bit Display Green vacuum fluorescent B-Versions Character size 5mm high, 5x7 dot matrix Text memory 16k CMOS RAM Brightness Adjustable – 4 levels Text call Binary (255 texts), BCD (99 texts), Serial (255 texts) or Direct (8 texts) Character sets ASCII, Cyrillic, German, French, Swedish/Finish, Danish/Norwegian Variable overlay Via Serial or Parallel interfaces Parallel interface ‘High’ level: +24V (+15…+30V) ‘Low’ level: 0V (0…+7V) Power supply 24VDC (19…36V), 6W, 1.5A peak 115 or 230VAC ±15%, 45…65Hz, 10VA Strobe Active or Passive Safety IEC 61010 Display modes First, Last, Sequence, Current or External control Temperature range Storage: -40 to +80°C Operating: 0 to +50°C Serial interface RS-232C, 110…2400 baud, 7 or 8-bit Dimensions (W x H x D) DAA 144: 144 x 36 x 147.5 mm DAA 288: 288 x 72 x 95 mm Serial output format ‘Normal’ to a printer, etc. ‘Slave’ to a DAA…A-Version Panel cut-out DAA 144: 138 x 33 mm DAA 288: 282 x 68 mm Alarm output Normally open relay contacts 30V, 2A Protection Front panel IP 65 A
