Description
Ajax 42837.19.NC3 Relay (9NA) UPC
Product Details
Relay Jeweller is a dry contact relay that switches a power supply remotely from the Ajax system. 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.
It 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.
Scenarios 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.
