TDMB Series Timer - Delay-on-Make/Delay-on-Break Features

TDMB Series Timer - Delay-on-Make/Delay-on-Break Features
Timer - Delay-on-Make/Delay-on-Break
The TDMB combines both delay-on-make and
delay-on-break functions into one plug-in package.
Selection of the time period is accomplished with
dual switches, one for the on delay and the other
for the off delay. SPDT or DPDT output options
provide isolated, 10A switching capability.
Operation (Delay-on-Make/Delay-on-Break):
Input voltage must be applied at all times. The output
relay is de-energized. Upon closure of the initiate switch,
the green LED glows and the delay-on-make time delay
(T1) begins. At the end of T1, the output relay energizes
and the red LED glows. When the initiate switch opens,
the green LED turns OFF and the delay-on-break time
delay (T2) begins. At the end of T2, the output relay deenergizes and the red LED turns OFF.
Reset: Removing input voltage resets time delay and
output. Opening the initiate switch during the delay-onmake delay, resets T1. Closing the initiate switch during
the delay-on-break delay, resets T2.
