1800 series - ELECTROMECHANICAL TIMER WITH A MOVING INDEX, MULTIRANGE WITH MANUAL RESET

Product catalog summary
Description: The document describes an electromechanical timer, model 72x72, which is multirange and features a manual reset. It includes a moving index to indicate elapsed and remaining time. The timer's settings can be adjusted using a large knob, and a mechanical gear on the side allows for scale changes. The timer operates with a synchronous motor and switches contacts at the end of the set time. Resetting is done via a button on the knob. It uses an Octal socket.
Features: The timer supports various supply voltages: 24 Vac, 48 Vac, 115 Vac, and 230 Vac at 50/60Hz. It offers multiple full-scale time settings across three bases: Base 3 (30s to 30h), Base 6 (6s to 6h), and Base 12 (12s to 12h).
Technical Data: The full-scale error is ±2%, with a minimum time setting of 1/60 of the full scale. The reset time is 0.4 seconds. It operates within a temperature range of -10 to +55 °C. The relay has an electrical life of 10,000 operations and a mechanical life of 10 million operations, with a current rating of 5A AC1 and a voltage rating of 250 Vac.
Order Code: The order code is structured as 1800 726 0 TT YYY, where TT indicates the base (B3, B6, B12) and YYY indicates the supply voltage (012, 024, 048, 115, 230).

TIMER ELETTROMECCANICO CON INDICE MOBILE, MULTISCALA A RIARMO MANUALE ELECTROMECHANICAL TIMER WITH A MOVING INDEX, MULTIRANGE WITH MANUAL RESET TEMPORIZZATORI ZOCCOLATISOCKET TIMERS DATI TECNICI / TECHNICAL DATA PRECISIONE DI FONDO SCALA / FULL SCALE ERROR ± 2% IMPOSTAZIONE MINIMA / MINIMUM TIME SETTING 1/60 f.s. TEMPO DI RESET / RESET TIME DESCRIZIONE / DESCRIPTION Temporizzatore elettromeccanico 72x72 multiscala a preselezione con riarmo manuale. Dotato di un indice mobile che segnala il tempo trascorso e residuo. Tramite la manopola di grandi dimensioni e’ possibile cambiare il tempo impostato. Sul fianco e disponibile un meccanismo per il cambio scala. Impostazione tempi su ampia scala graduata (50 e 60 Hz). L’inizio della temporizzazione avviene con l’alimentazione del motore sincrono. Alla fine del tempo impostato si ha la commutazione dei due contatti ritardati e l’esclusione del motore. Il ripristino sulla posizione avviene tramite un pulsante meccanico incorporato nella manopola di impostazione. Zoccolo Octal. Electromechanical multirange 72x72 timer. With a rotating index that points out the passing time. Time setting by rotation of the large knob. Manual reset. On the side of the timer , it is available a mechanical gear-set to change the full scale time. The timer starts with the power supply to the sinchronous motor. At the end of the time the two switches switch. The reset is made by the button on the knob. Octal socket .
