The DSH-10 driver is specifically designed to control the SH-10 optical shutter. In the event of power loss, the SH-10's fail-safe feature causes the shutter to quickly spring to its aperture blocking, closed position. The driver is easily operated using the TTL mode or manual mode control switch.
In TTL mode (top position of the control switch), the shutter is controlled by an external TTL voltage at the terminal block. A TTL high voltage closes the shutter aperture and a TTL low voltage opens the shutter aperture. TTL input is pulled high so when no signal is present the shutter closes. The driver my be ordered with an optional BNC connector to input the TTL signal.
In the manual mode, the shutter is locally controlled by moving the control switch to the open position (bottom position of the control switch) or the close position (center position of the control switch). Manual mode overrides any external TTL signal present.
