The Vincent / UniBlitz SD-1000 Shutter Drive / Timer delivers precision exposure control for UniBlitz electro-programmable shutters in demanding scientific and industrial imaging environments. Crystal-controlled timing accuracy of ±0.01% combined with variable recycle intervals and selectable repeat exposure modes enable repeatable, frame-accurate shutter sequencing from microsecond to multi-second exposures.

– Key Features
• Manual trigger and reset controls on front panel
• 4-digit thumbwheel switches for exposure time programming across 3 decade ranges
• Timer bypass mode allows external pulse width to control exposure duration
• External trigger input via BNC (10K ohm impedance, 3.5 VDC minimum, 1 µs minimum pulse width)
• Pulse In/Out BNC connector for external timing control
• Multiple rear panel shutter connectors: 5-way binding posts, 4-pin female, 7-pin female
– Typical Applications
High-speed photography, scientific imaging, industrial quality control, stroboscopic analysis, and precision timing applications requiring exposure control in the microsecond to second range.
– Compatibility & Integration
Designed for direct control of UniBlitz electro-programmable shutters. Accepts external trigger signals and supports external pulse-width timing modes via dedicated BNC inputs.
