TH1 SeriesTimer - Delay-on-Make
Connection:
L1 N/L2
The TH1 Series is a solid-state relay and timer
combined into one compact, easy-to-use control.
This highly reliable device eliminates the need
for a separate solid-state relay. When mounted to
a metal surface, it can switch load currents up to
20A steady state, and 200A inrush.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains 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.
Features:
• High current load capacity up to 20A with
200A inrush
• Solid-state switching - no contact wear
or arcing
• Encapsulated
• Fixed or adjustable time delays from 0.1 - 600s
• ± 2% repeat accuracy
• ± 5% factory calibration
• Metallized mounting surface for heat transfer
