SH-2 Shutter Controller Option

About the SH-2 Option

The SH-2 shutter card allows you to control the operation of two ASI shutters, and takes up a single slot in the Tiger Controller. Typically the SH-2 is used along with other modules, such as the FW-1000 filter wheel controller.

Shutters connected to the SH-2 can be controlled with the front panel toggle switch, with TTL inputs via BNC connectors on the front panel, by a foot switch connected to the same BNC connectors, and with RS-232 commands via the FW-1000 filter wheel controller (if one is installed in the same cabinet with the SH-2).

We only provide controllers and shutter housings for Uniblitz VS25 series shutters. The shutters must be purchased separately from Vincent Associates. See
