The electronic temperature switch of BEDIA is fitted with thin-film resistor Pt 1000 in a bridge circuit. This sensor element provides close switch point tolerances and a quick response. Switch point and reset hysteresis may be selected within the admissible operating range when ordering so as to allow the monitoring of both very wide and very close temperature ranges. The switching output is protected from short-circuit and overload. The short-circuit current is limited by the output transistor switching off inthe event of a fault. It will automatically reset as soon as the fault has been remedied. The switch is available with ground-connected, plus-connected or potential-free DC switching output. The switch is open in the event of power failure or disconnection of the power supply, independed of the switching function. It is available both as normally open (NO) or normally closed (NC) switch.

The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.
