(Resistive);
ENVIRONMENTAL INFORMATION
True delay on dropout: Timing cycle after power removal
DPDT (2 form C) isolated 4 ampere relay contacts
Built-in timing adjust potentiometer
Numerous models from 0.1 seconds to hours
Timing Mode
Upon the application of input voltage the relay immediately
energizes. The timing cycle begins when input voltage is removed.
When the timing cycle is complete, the relay will de-energize
