Noted for its circuit flexibility, the 305E also provides the highest accuracy among analog timers. Available for either ON-Delay or OFF-Delay operation.

The 305E provides delay, interval or pulse timing function for up to 7 load circuits through two instantaneous and two delayed switches. It features a plug-in design and cycle progress indication.

Highest Accuracy:Because of its exclusive infinite engagement clutch, the 305 has a repeat accuracy of 0.2%, highest of any timer in its class.

Plug-in and Dust-Tight Design:By virtue of its true plug-in design, the body of a 305E can be replaced in seconds without disturbing the housing or disconnecting the wiring. Its gasketed dial assembly forms a dust-tight seal against the housing, whether panel or surface-mounted.

Fastest Reset:All 305 timers reset to a full-scale setting within 0.1 second, proportionately faster for shorter settings.

Circuit Flexibility:All the contacts of its two instantaneous and two delayed load switches are externally accessible at a 14 point terminal block.

Longest Life:With an average mechanical life expectancy of over 5,000,000 operations before the first failure, the 305E is the leader in its class.

Pilot Light:A built-in pilot light indicates that the timer is running.
