800.727.5646 atcdiversified.com Diversified Electronics TBU Series Time Delay Relays // TBU Series 67 Programmabl e Mu l t i-Mod e D I P Sw i t c h T DR The TBU Series offers the accuracy of DIP SWITCH delay ranges “A” through “E” as well as the user programmable model, DIP SWITCH delay range “P,” with 4 different ranges obtainable by either leaving 2 designated terminals unconnected or by connecting them to the appropriate terminals as shown below. The 6 most common modes of operation are easily selected by the use of one or more jumpers applied externally between designated base pins as outlined below. These features, coupled with 6 most popular supply voltages, make this timer one of the most versatile and cost effective Time Delay Relays available today. The CMOS digital circuitry provides high accuracy, repeatability and fast reset times. DIP SWITCH OPERATION Digital selection of the time delay is accomplished by the use of ten (10) binary switches, each marked with a time increment. The time periods, of which there are five (5) ranges, represented by each switch in the ON position is added together to obtain the desired time delay. No more trialby- error adjustments.

TBU Series Diversified Electronics atcdiversified.com 800.727.5646 68Time Delay Relays // TBU Series INTERVAL: When supply voltage is applied to the input terminals, the relay energizes and the time delay begins. Upon completion of the delay period, the relay de-energizes. Reset during or after the delay period is accomplished by removal of the supply voltage. ON-DELAY: The time delay begins when supply voltage is applied to the input. Upon completion of the delay period, the relay energizes. Reset during or after the delay period is accomplished by removal of the supply voltage. The timer...
