Delay On Make / Interval Timers

 

The Model 438USA Delay On Make / Interval Timers are universal switch-adjustable time capsules in a solid state timer. These interval timers provide delay on make (ON-Delay) control of a load device operating from 19-288 volt AC/DC. The Model 438USA timer controls up to a 1A load, such as a relay or solenoid. The Model 438USA-INT universal switch-adjustable time capsule is an all solid-state timer that provides interval timing control of a load device operating from 24 to 240 volt AC. The 438USA-INT controls up to a 1A load, such as a relay or solenoid.
