ESU-8 8 Channel Timer -  ESU-8


The ESU-8 8-channel Digital Timer Unit with 7-day event switching.

The ESU-8 is an 8-channel Digital Timer Unit, for programmed weekly event switching of 8 independent relay outputs. Ideal for class change signals, shift start/stop applications, tone generators, or digital message scheduling.

The ESU-8 Digital Timer provides NO (Normal Open) or NC (Normal Closed) relay contacts to each of its 8 relay outputs and supports switching up to 64 events per day (32 On and 32 Off).

Further functions of this Digital Timer Unit include event manual override, DST (daylight saving time) compensation of spring/autumn time changes, and clock tuning for maintaining the accuracy of the timer.

The LCD screen displays the timer status as well as menu functions for programming and set-up. Push buttons control the user interface for programming and a row of 8 green LEDs provides a visual indication of when each relay is active. The relay outputs and power are connected via removable phoenix terminals which are housed under a removable security cover to prevent unauthorized access or tampering.
