It is how a security system stops being only a set of sensors: a gate opens, an electric lock releases, a water valve closes, blinds come down, a smoke cannon fires.\u003c\/p\u003e\n\u003cp\u003eIt switches up to 5 A at 24 V DC or 13 A at 110–230 V~ resistive, and up to 3 A \/ 8 A inductive or capacitive, from a 7–24 V DC supply drawing under 1 W. Pulse duration is adjustable from 0.5 to 255 seconds, in pulse or bistable mode, with normally open or normally closed contacts. Jeweller radio reaches 3,250 ft in open space.\u003c\/p\u003e\n\u003cp\u003eScenarios can fire it on arming and disarming, on a schedule, on an alarm, on temperature, humidity or CO₂, or on user input. Built-in protection cuts the relay if voltage falls below 6.5 V or rises above 36.5 V, or if the installation site exceeds 149 °F or the relay's own interior exceeds 185 °F. It fits a DIN rail with the separate DIN Holder bracket.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDry contact relay for remote control of a 7–24 V DC power
