24-Hour Electromechanical Timer
The Intermatic T1905 is a 24-hour electromechanical timer housed in a steel enclosure rated NEMA 1. It provides SPDT switching at 120V AC with a 20 A rating and 1/2 hp contact rating at 120V. The unit supports up to 48 on/off cycles per day with a minimum setting of 15 minutes.
Industrial and Outdoor Control Panels
This timer suits installations that require multi-operation scheduling in a rugged steel case. It operates across a -40 to +130 degree temperature range. Buyers who need a day-skipper function or a different voltage supply should look at alternative models.
Sustained Load Behaviour
Under continuous operation the contacts maintain their 20 A and 1/2 hp ratings at 120V AC. The mechanical dial and 96 included trippers allow repeated daily programmes without electronic drift. The steel enclosure and wide temperature rating support reliable switching in unconditioned environments.

Questions about this item
What voltage supply must my circuit provide for the T1905 timer to operate?
The timer requires a 120 V AC supply to power its electromechanical motor and switching contacts.
Can the T1905 switch a 240 V load such as a 1 hp motor?
Yes, the SPDT contacts are rated 1 hp at 240 V AC, so they can control that motor directly.
How can I verify the timer is cycling correctly after installation?
Observe the dial rotate through a full 24-hour period; each of the 96 trippers should trigger a distinct on/off action up to 48 cycles per day.
