Time Delay Relays Dedicated - Dual Function TDMB SERIES Delay-on-Make/Delay-on-Break Description 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. 8-PIN 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 de-energizes and the red LED turns OFF. 11-PIN Reset: Removing input voltage resets time delay and output. Opening the initiate switch during the delay-on-make delay, Wiring Diagram resets T1. Closing the initiate switch during the delay-on-break delay, resets T2.
