SSAC TH2 Series Data Sheet
TH2 SeriesTimer - Interval
L1 N/L2
Connection:
The TH2 is the combination of a timer and a solidstate relay into one easy-to-use solid-state molded
module. When mounted to a metal surface, the
TH2 Series can switch load currents up to 20A
steady state with 200A inrush. The TH2 replaces
a timer and relay at a competitive price.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output energizes during the time delay. At the end
of the time delay, the output de-energizes and remains
de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output.
For more information see:
Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 4 for dimensional drawing.
