Abstract
A device to audibly verify the activation of a solid state relay. The device includes an audio output device that is coupled to the solid state relay to produce a sound when the solid state relay is activated. The sound produced by the audio output devices emulates the sound of an electromechanical relay when switched.
Claims38
An audible relay emulator comprising:
- one or more solid state relays;
- and
- an audio output device coupled to each of the solid state relays to produce a sound to indicate when one of the one or more solid state relays is activated in response to a user input.
A network node having an audible relay emulator circuit, comprising:
- one or more solid state relays housed in the network node;
- and
- one or more audio output devices housed in the network node, each one of the one or more audio output devices is coupled to one or more of the one or more solid state relays to produce a sound to indicate when one of the one or more associated solid state relays is switched to replace a first operating circuit with a second operating circuit.
An audible relay emulator comprising:
- one or more solid state relays coupled to receive one or more control signals, wherein each of the control signals are adapted to activate an associated solid state relay to replace a first transmission path with an associated second transmission path;
- and
- an audio output device coupled to receive the one or more control signals, wherein the audio output device produces a sound in response to receiving each of the one or more control signals to indicate activation of one of the one or more solid state relays.
An output signaling circuit comprising:
- one or more solid state relays;
- a visual output device coupled to each of the solid state relays to produce a visual signal when one of the one or more solid state relays is activated;
- and
- one or more buffer circuits, each buffer circuit coupled to buffer a control signal in activating an associated solid state relay.
1 more element
A method of operating a solid state relay circuit comprising, the method comprising:
- activating the solid state relay;
- and
- producing a sound when the solid state relay has been switched to indicate activation of the solid state relay, wherein the sound produced emulates the sound made by an electromechanical relay when it is activated.
