A safety torque off (STO) device interrupts torque generation by an elevator installation drive machine supplied by a power supply device being part of an inverter device, for example. The STO device includes a control input, signal input terminals connected to signal generation device outputs and signal output terminals connected to driver circuit inputs. Each of the STO signal input terminals is electrically connected to an associated one of the signal generation device outputs via first and second signal transmission switches connected in series. The control input is connected to first and second control units, wherein the first control unit, controlled by a control signal applied to the control input, switches switching states of all the first signal transmission switches and the second control unit, controlled by a control signal applied to the control input, switches switching states of all of the second signal transmission switches.
