This means that the relay will “monitor” the load signal and when this signal gets to the zero volt (amplitude), the relay will trigger after the control voltage has been applied. This will usually take about 8.3msec in a 60Hz signal. These type of relays are mainly used to switch resistive or capacitive loads. Control Voltage Range: 3−15VDC Must Operate Voltage: 3.0VDC Must Release Voltage: 1.0VDC Nominal Input Impedance: 300Ω Typ. Input Current (@ 5VDC): 15mA RANDOM TURN−ON − This type of relay does not contain a zero cross detector. Therefore, as soon as you connect a control signal, the relay will immediately turn−on at any phase of the load sine wave. The relay will trigger in a maximum time of 20µsec after the control voltage has been applied. These relays are mainly used to switch inductive loads.
