Actuate Relay (AQ)

the aq series adds an additional feature of integrating a fuse with one of the relay channels in the case of the aq, the no(normally open) side of the relay includes a blade fuse when the relay is actuated, the no side closes, and this action is fused, protecting both the equipment and the relay this ensures the following the rated current value of the normally open is not exceeded if the device powered by the relay actuation has a higher current demand, the fuse will protect the relay and the device the relay's contacts are protected by the integrated fuse use applications this i/o board is particularly designed to function from a 12vdc power source, which makes it ideal for automotive applications whether installing a new item of equipment in your vehicle or using it in a camping/outdoors application, the actuate offers a reliable actutator junction to enable or disable devices pcb layout the pcb layout is displayed below and illustrates the connection points the relays are driven from the relay inputs, and this actuates the relay, closing the contact connection description i1 i4 relay inputs labelled 1 through 4 connecting the relay coil to its power source once 12vdc is applied, the contact closes o1 o4 the relay inputs are tied directly to the corresponding relay output actuate relay \[aq] normally open contact with integrated fuse the corresponding relay input channel actuates the corresponding relay output by supplying 12vdc at the input contact actuates the relay fuse blow indicator the fuse blow indicator is an led that is connected in parallel with the no contact track if the fuse is not present or blown, the led will illuminate condition fuse state led indicator relay open fuse not blown led deluminated relay closed fuse not blown led deluminated relay closed fuse blown led illuminated the blade fuse is the same fuse that is used in automobiles, and these fuses are readily available and common to many transport applications power requirements the i/o board operates on a direct drive principle, driving the 12vdc coil directly parameter description input voltage 12vdc relay rating 10a 30vdc | 230 volts alternatively, as per the relay rating printed on the device
