supervisory circuit การใช้

• On calls which terminated on the exchange a transmission bridge and supervisory circuit needed to be introduced within the switching network.
• Supervisory circuits that specifically focus on voltage regulation are often sold as supply voltage supervisors and will reset the protected circuit when the voltage returns to operating range.
• An external supervisory circuit converts the time delay between input and output into a voltage applied to the ionic liquid that either drives ions into the SNO or removes them.
