The QTP 12/R84 is a powerful module with inputs, outputs and operator interface. It contains a complete PLC controller capable of total management of specific applications of a minimum size, specifically designed for industrial and/or domestic use.

The QTP 12/R84 is available with alpha-numeric displays of 20 characters over 2 lines in two different types: LCD type with LED backlight or fluorescent, or alternatively with Graphic Fluorescent display with 140x16 pixels. On the front panel there is a 12 Keys membrane keyboard, a label slot used to carry a name for the QTP 12/R84 or the user's own logo, and a status LED.

A practical and robust metallic container in the standard DIN 72x144 size allows a direct mounting in front panel modality with a protected front side and back openings for connections. The enclosed brackets supplied with QTP 12/R84 let the user mount and/or dismount the terminal simply on the support panel. Alternatively it can be used on a table with no elements addition.

The module's serial line can be buffered with the most frequently used electric protocols and thanks to this feature the QTP 12/R84 can be connected to various systems available on the market and moreover low cost networks can be realized where many different units can be contemporaneously managed. The interconnection with other devices is ensured also by the optional CAN line, that increase the possible applications fields and gives better performance of the complete network.

The CPU section features 32K FLASH with ISP interface for comfortable programming through a serial line. This allows an easy development environment, that does not require an additional system meaning considerable cost reductions. The user can write the application program with 8051 compatible code, by using one of the numerous high level development tools as the convenient BASIC compiler BASCOM 8051; the efficient C compiler µC/51 or the well known LadderWORK for users that require contacts programming.
