The TP 1011 enables the construction of test setups in basic and further training in electrical engineering and electronics as well as in digital and control technology. Even complex circuits can be constructed quickly and easily using the individual plug components on a socket panel that is supplied with energy via a power supply unit. The plug components are safety engineered and designed specifically for a training environment: for example, the printed circuit symbol corresponds with the component actually used on the circuit board, which is visible through the transparent window.
