ATEX message display TA125 series

The field text display TA125 indicates arbitrary messages, warnings or hints in the hazardous area zone 1. It's large (58 x 244 mm), reflective display with a figure height of 15 mm can easily be read up to a distance of five meters. The display is organised into 4 rows with 40 characters per each row. The TA125 receives the messages for instance from a PC or DCS located in safe area.
The interface TI125 serves as intrinsically safe barrier and power supply. It can be equiped with several bus modules (RS232, RS485, RS422, Profibus DP, Interbus and Modbus). The distance to the TA125 could be up to 300 meters with a data rate of 38,4 kbit/s. Use bigger wire diameter for longer distances. It is possible to connect many text display to one bus (theoretical up to 256). Each one with a different text content. Additionaly the TA125 has an intrinsically safe passive alarm output. With this it is possible to connect a further alarming device. With the three digital inputs you can acknowledge a message or an alarm or you can request further information on the spot in hazardous area.
The TA125 stores up to 32 kByte of messages in a internal EEprom. You can program the prestored messages with the bundled windows software 'TEXT LINK'.
There are two ways to display the prestored texts: the serial interface or applying a defined bit pattern to binary address inputs of the TI125 (option).
