<p>The subject of the invention is an EIB module, which consists of a universal, programmable bus connector and a terminal device with up to four input or output channels. A test button (T1) and a signal diode (D1) are assigned to each channel. Also, a logical switch (20) is provided, the bus control signal (BS) is present at one of its inputs, and the test signal (TS), which is triggered by the test button (T1) being pressed, is present at its other input (22). An actuator simulation signal (AS1) then appears at the output (23) e.g. of an output channel, and causes a relay (RL) to pick up, following which a supply voltage is present at an actuator clamp (A1). The switch (20) is an OR gate, which is connected so that the bus control signal (BS) which is present at the input (21) has priority over the test signal (TS). The signal diode (D1) is connected between the line (23) with the actuator simulation signal (AS1) and the internal power supply. <IMAGE></p> |
