VLM1 FS Shutter Interface Module


Current Lead Time: 3 – 4 weeks


Jump to: What’s Included | Specifications | Downloads

The Uniblitz FS series shutters do not require a driver for operation (only +5V to open and 0V to close), so for applications that require remote operation of the shutter from a TTL signal or USB interface, the VLM1 Interface Module is available.

This device also offers an optional Electronic Sync interface along with a SYNC Output BNC. Additionally, the device can be operated using a USB interface which will use the computer’s power to operate the VLM1 and the attached shutter.

The VLM1 is RoHS compliant.

What’s Included

  • VLM1 Interface Module
  • Manual (included on flash drive)
  • USB5 +5V 1A (5W) USB Power Supply
  • USB A 2.0 to USB Micro B Interface Cable
  • Micro Screwdriver (to install shutter leads)

USB/Power Input (1) +5VDC 0.5A min (USB5 +5VDC 1A wall adapter included). A USB interface cable (USB A 2.0 to USB Micro B) is included for use with the USB5 power supply, or it can be connected to a computer to supply power and data.
Pulse Input BNC (2) For shutter control via a +5V TTL signal – pulse width determined exposure time. Active High or Active Low (default) is selectable with an internal jumper.
Sync Output BNC (3) For shutters equipped with electronic sync systems. Active High or Active Low (default) is selectable with an internal jumper.
5-Pin Pluggable Spring Terminal (4) For shutter termination and sync system interface. The flying leads from the FS series shutters can connect directly to this terminal (no adapter is necessary).
