Altronix DTMR1 Multi-Purpose Timer, 12/24V DC, Includes ST3 for DIN Rail Mounting

Streamline timed operations for access control, alarm and monitoring systems with the Altronix DTMR1 multi-purpose digital timer. Designed for security integrators and facility managers, this compact DIN-rail mount timer delivers flexible timing modes—One Shot, Delayed Release and Delayed Pulse—so you can handle door hold-open, siren cut-off and supervisory timing without adding extra devices. The DTMR1 accepts 12V or 24V DC power for easy integration into existing panels and features an adjustable 1 second to 60 minute range to match precise system requirements. A one-second momentary relay at the end of the timing cycle provides instant, reliable activation for alarm or notification circuits, while the SPDT relay rated at 8 A handles common loads found in alarm and access control applications. Built in the USA, NDAA compliant and RoHS certified, the DTMR1 includes the ST3 snap track and mounting clips for fast DIN-rail installation. Backed by Altronix quality and a limited lifetime warranty, it’s an efficient choice for surveillance, intrusion and monitoring projects. Add the DTMR1 to your next access control or alarm panel installation to save space, wiring and setup time.
