SWPDC
Series
TDR
Timing Mode:
Delay on operate timing cycle begins upon application of input power. The relay contacts
transfer at the end of the delay period and will remain transferred until input voltage is
removed. Reset occurs when input voltage is removed.
Timing Diagram:
… Solid state CMOS digital circuitry
… Delay on operate timing mode
… DPDT (2 form C) isolated 10 ampere relay contacts
… Timing selection: 5 position binary coded Dip Switch plus
vernier knob adjustment
… Twenty overlapping timing ranges covering .25 secs. to
160 hours.
… UL File#E96739 (M)
… CSA File #LR62586

Timing Specifications:
Standard Timing: The SWPDC has 20 overlapping timing ranges covering 0.25 secs. to
160 hours. Timing is user selectable by means of a 5 position binary coded Dip Switch
and a knob adjustable potentiometer allowing the time delay within the selected timing
range to be set precisely.
Timing Adjustment: 5 position binary Dip Switch coded as follows:
