  • circuit diagram needed

    of the the very kind, grateful people, who feel happy to do a deed of kindness I ask a favour: how may I have schematic circuit diagrams for a logic probe and a heat activated fire alarm circuit.

  • Re: Maintenance for Static Switches

    Reply to: hara143 #3 " Two redundanct UPS outputs will be connected to static switch input. The static swithc provides reduncanct supply to rack which houses the servers. In order to maintain the reliability of power this config is used in Data center. If one of power fails the static switche...

  • Re: logic -control narrative

    Logic is a command given in the control circuit. Depending on how the program is written it will create an output to turn something on or off depending on your inputs. Think of a fire alarm. All inputs are normal and as programmed until a fire starts and one of your sensors gets too hot. It imm...
