Introduction
Thank you for purchasing the
TU-8A 8 Channel Digital Timer Unit
.
The TU-8A is a weekly event programmable timer providing 8 independent relay outputs
for general apparatus control. Each output is capable of providing either a NO or NC
relay contact. Providing 64 events per day (32 on and 32 off) the TU-8A is ideal for
applications in Education, Industry and Retail environments where the timed broadcast
of tones, messages or audio files is required (via a separate message device such as the
LB-8A).
Further functions include an option to manually override events , DST (day light saving
time) for compensating for spring and autumn time changes and clock tuning for
maintaining accuracy of the timer.
A clear blue LCD screen displays the timer status as well as menu functions for
programming and set up. Push buttons provide the user interface for programming,
a row of 8 green LED’s provide a visual indication of when each relay is active. The
relay outputs and power are connected via removable phoenix screw terminals, which
are housed within a removable security cover to prevent unauthorised access to the
connections. Removable brackets allow the device to be securely fastened to a wall.
