DELAY PERIOD

See page 82 for standard ranges available

On-Delay Relay Output

OPERATION

The time delay begins when power is applied to the input. Upon comple-

tion of the delay period, the relay energizes. Reset during or after the

delay period is accomplished by removal of the input voltage. The TDC/

TUC will not false transfer if voltage is removed prior to completion of

the delay period. A fast recycle time permits accurate, high speed,

continuous operation.
