SH05 Shutter Overview

The SH05 shutter contains a rotary solenoid presenting a large inductive load to
the controlling device. As this inductor is charged, the resulting movement of the
actuator takes a finite amount of time (opening of the shutter). Conversely when
the voltage is removed from the shutter it takes a finite time for the inductor to
discharge and for the mechanics to release the actuator (close the shutter). The
shutter timing varies and is dependent on the duration and magnitude of the driving
pulse and the magnitude of the sustaining hold voltage.
The SC10 provides a 5 millisecond 24 V driving voltage to actuate the shutter and
a holding voltage of 10 Volts. The timing for the SH05 is characterized below when
operated with the SC10 controller.
