+5VDC directly across the coil opens the shutter, while removing the +5VDC (0VDC) closes the shutter. A simple control circuit can be used to operate the shutter device from a TTL trigger pulse.
This control be also accomplished with our new VLM1/VLM1B Interface Modules. These units, for use exclusively with our FS shutter series, are for applications that require remote operation of the shutter from a TTL signal or USB interface. The FS series, when used with the VLM1/VLM1B interface modules, is a high-value optical shutter system capable of flexible integration into an array of different applications.
