Timers switch a contact on or off at set times. They help to implement energy-saving measures. The mechanical UNO timers control an electrical load circuit using daily or weekly programs. The automatic program can be switched off. Some models have a power reserve. This ensures that the consumers are reliably switched even in the event of a temporary power failure. Properties: - mechanical switching wheel with captive switching slides, - daily program (Uno-D, Uno-QRD) or weekly program (Uno-QRS), - smallest switching times of 15 minutes (Uno-D, Uno-QRD) or 2 hours (Uno-QRS) - power reserve: none (Uno-D) or 150 hours (Uno-QRD/-QRS) - high accuracy, - control switch for continuous operation, - 1 potential-free normally open contact 16 (4) A / 250VAC, - operating voltage: 230VAC, - low power consumption, - sealable transparent cover, - module width only 1 pitch unit (17.5mm), protection class IP 20 Mounting type: - quick attachment to mounting rail - installation position as desired Areas of application: Timers for the time-dependent control of any electrical consumers in private, commercial or industrial applications.
