Electronic engineering
capacitance relay
Engineering; Electronic engineering
A relay circuit that operates from a small change in its own capacitance. It consists of an RF oscillator whose tank capacitance is very low. When a finger is brought near the circuit’s short pickup ...
coaxial relay
Engineering; Electronic engineering
A relay designed to connect and disconnect, or to interchange, coaxial cables in a transmission line without disturbing the characteristic impedance of the line.
ac relay
Engineering; Electronic engineering
A relay designed to operate on alternating current without chattering or vibrating.
dc relay
Engineering; Electronic engineering
A relay having a simple coil and core system for closure by direct current, which can be rectified ac.
dc overvoltage relay
Engineering; Electronic engineering
A relay or relay circuit actuated as a result of the dc coil voltage rising above a specified level. Compare dc undervoltage relay.
dc overcurrent relay
Engineering; Electronic engineering
A relay or relay circuit actuated by dc coil current rising above a specified level. Compare dc undercurrent relay.
dc undercurrent relay
Engineering; Electronic engineering
A relay or relay circuit that is actuated as a result of the dc coil current dropping below a specified level. Compare dc overcurrent relay.
