Digital input and/or output module for controlling digital consumer e.g. relay, has FET arranged in drain line of another FET and connected anti-parallel to latter FET, where former FET includes control line with input signal of board

摘要

The module has input and output channels that are arranged on a circuit board and supplied with a common supply voltage (6). Each channel has a control input (1), and a FET (4) is arranged at the control input, where the FET comprises a source-line (5) and a drain-line (7) that is connected with a branch of the circuit board. Another FET (24) is arranged in the drain line and connected anti-parallel to the former FET. The latter FET has a control line with an input signal of the circuit board.
