The DSH-20 driver can operate the SH-20 Laser Safety Shutter.
The DSH-20 driver includes a three position control switch. In the "OPEN" position, the shutter is continuously open. In the middle position, the shutter is continuously closed. In the "TTL" position, an external TTL signal controls the shutter. A high or open circuit at the TTL input will set the shutter to the closed position. A low or short to ground at the TTL signal will set the shutter to the open position.

SH-20 Laser Safety Shutter.
The DSH-20 driver includes a three position control switch. In the "OPEN" position, the shutter is continuously open. In the middle position, the shutter is continuously closed. In the "TTL" position, an external TTL signal controls the shutter. A high or open circuit at the TTL input sets the shutter in the closed position. A low or short to ground at the TTL signal sets the shutter in the open position.

The following driver models that enable the user to control the shutter with a TTL signal are available:
DSH-20-110 or DSH-20-220, a cased driver 5.3" x 5.3" x 2" operating from a line voltage of 110Vac or 220Vac (please specify DSH-20-110 or DSH-20-220).
DSH-20-110/220, a cased driver 5.3" x 5.3" x 2" with a selector switch for operating from a line voltage of 110Vac or 220Vac.
DSH-20-110-BNC or DSH-20-220-BNC, a cased driver 5.3" x 5.3" x 2" operating from a line voltage of 110Vac or 220Vac (please specify DSH-20-110 or DSH-20-220) with a BNC connector for TTL input.

The DSH-20-110 can driver two SH-10 shutters simultaneously.
