Abstract
A circuit comprises a mechanical relay and a solid-state relay. The mechanical relay is configured to switch a first supply current of the first heating element on a first supply line. The solid-state relay is configured to switch a second supply current of a second heating element on a second supply line.
Claims20
A circuit comprising:
- a mechanical relay configured to switch a first supply current of a first heating element on a first supply line;
- a solid-state relay configured to switch a second supply current of a second heating element on a second supply line, the second supply line being different than the first supply line;
- and
- a control device connected to an input interface and further connected to a control interface, wherein the control device is configured to:
- receive an input signal via the input interface;
- establish, depending on the input signal, a first control signal and a second control signal, wherein the first control signal prompts the mechanical relay to either switch on or switch off the first supply current on the first supply line, and wherein the second control signal prompts the solid-state relay to alternately switch on and off the second supply current on the second supply line;
- send the first control signal via the control interface to the mechanical relay;
- and
- send the second control signal via the control interface to the solid-state relay.

A method, comprising:
- receiving by a control device connected to an input interface and further connected to a control interface, an input signal via the input interface;
- establishing, by the control device and depending on the input signal, a first control signal and a second control signal;
- sending, by the control signal, the first control signal via the control interface to a mechanical relay;
- and
- sending, by the control device, the second control signal via the control interface to a solid-state relay,
- the first control signal prompting the mechanical relay to either switch on or switch off a first supply current of a first heating element on a first supply, and
- the second control signal prompting the solid-state relay to alternately switch on and off a second supply current of a second heating element on a first supply line, the second supply line being different than the first supply line.
