Overview

Eaton's type TR range of time relays comprises 3 models offering 9 different functions to meet the varied time control needs required for controlling such applications as fans, pumps and lighting.
By having a flexible supply and control voltage input the time relays can be easily applied without the need of additional power supplies. The status of supply voltage, time sequence and output relay is visible on the front by LED indicators. All rotary adjustment buttons are located on the front. The recessed position of the buttons prevents from unintentional adjustment. All models are of a compact design, 18 mm wide. Staggered terminals allow easy access to the lower level terminals even if upper terminals are wired.
