CUBE–SOLID STATE
Timing Mode
Application of input voltage to the timer starts the
time delay. At the end of the delay period, the
load is energized. To reset, remove the input
voltage to the timer.
THC Timers
THC timers are solid-state output
units with digital timing. The TH
comes in a 2" square case.
Ease of installation and hook-up is a
primary design benefit. All models
with integral time adjustment knob or
factory-fixed time require only two
connections. They may be wired inline just like a single pole switch.
Units with external time adjustment
have two additional terminals for the
resistor or potentiometer.
