SECURE MOTOR STARTER

摘要

The invention relates to a secure motor starter having a security evaluation unit (1), having a first interface (11), and a secure switch unit (2) having a fourth interface (21), wherein the secure switch unit (2) can securely control a supply voltage of a consumer (4), wherein the security evaluation unit (1) can transmit a control command via the first interface (11) to the fourth interface (21) of the secure switch unit (2). According to the invention, in order to provide an improved motor starter, the motor starter further comprises a connection module (3), which comprises a second and third interface (31, 32), wherein the second interface (31) is electrically conductively connected to the third interface (32), wherein the security evaluation unit (1) can be mechanically coupled to the connection module (3) so that an electrically conductive connection is produced between the first and second interfaces (11, 31), and the secure switch unit (2) can be mechanically coupled to the connection module (3) so that an electrically conductive connection between the third and fourth interfaces (32, 21) is produced, so that, in the coupled state of the security evaluation unit (1) and the secure switch unit (2) to the connection module (3), there is an electrically conductive connection between the first and fourth interfaces (11, 21) via the connection module (3), so that the control command can be transmitted from the security evaluation unit (1) via the connection module (3) to the secure switch unit (2).
