WebWhen using mechanical contacts, switches, push-buttons, other relay contacts, etc, as the activating signal, the supply voltage used can be equal to the SSR’s minimum input voltage value, whereas when using solid state devices such as transistors, gates and micro-controllers, the minimum supply voltage needs to be one or two volts above the SSR’s turn … WebEMD monitoring relays can be used to monitor overvoltage, undervoltage, overcurrent, undercurrent, phase failure, phase sequence, phase asymmetry, power factor, active power, motor winding temperature, and fill levels. The current relay detects and monitors sinusoidal alternating currents in the frequency range from 45 to 65 Hz. More information.
