This shutter driver device complies with CE, UL, CSA standards for laboratory equipment. For externally timed control, the VCM-D1 is ideal. In addition to shutter control from the BNC inputs, these inputs can also be controlled via a computer serial ports (RS-232C). By selecting the proper address for each unit, a number of devices can be controlled from one serial port. Eight individual addresses are available. Easily daisy chain up to 8 units together using 810RJ cables.

With key selection, the VCM-D1 can be operated in any one of three modes, outlined under features, depending on the application. In addition, it can be used for normally-closed and normally-open shutter configurations. Exposure control can be activated by external pulse or remote actuate cable. Reset can be accomplished by external pulse, front panel reset switch or remote actuate cable.


  • CE/UL/CSA certification.
  • Replaces the VMM-D1 controller.
  • Three modes of operation to be selected with key switch.
    1. Standard shutter operation (STD) exposure determined by external pulse source or switch contact closure.
    2. Line interrupt (A) with power loss; unit powers down. When power is restored, unit must be manually or remotely reset to resume standard operation.
    3. DC interrupt (B) detects break in external switch contact. When continuity is restored, unit must be manually or remotely reset to resume standard operation.
  • Normally-open or normally-closed shutter operation.
  • Exposure determined by external pulse (BNC, TTL) or switch contact closure.
  • Pulsed on/pulsed off exposure control (BNC, TTL) from external trigger pulse or remote actuate cable.
  • Reset from external pulse (BNC, TTL), front panel reset pushbutton switch or remote actuate cable.
  • All BNC outputs can be selected to source either active-high or active-low.
  • All BNC inputs can be selected for control from a rising or falling edge.
  • RS-232C input and output connection accessible via dual RJ45 connector.
  • All inputs and AUX output controllable via RS-232 interface.
  • Logic state of AUX output controlled via commands from the RS-232C input.
  • RS-232C interface addressable via 8 selectable addresses.
  • Up to 8 units can be controlled independently from one computer serial port.
  • Units can be easily daisy chained with RJ45 cable, 810RJ.
  • LOCAL/REMOTE switch allows manual operation of the shutter without requiring removal of external input signals.
  • Exposure pulse output BNC, TTL.
  • Electronic synchronization output BNC, TTL
  • Electronic Synchronization system can be disabled via rear panel function switch.
  • Selectable pulse energy for operation of the VS35, CS45 and CS65 shutter types.
  • ODU shutter interface connector.
  • 710B shutter interconnect cable included. (7-pin WPI female to 7-pin ODU male, 3 meters.)
  • Black aluminum enclosure with slots for ventilation.
  • Operates on both 115AC and 230 AC voltages, manual switching as required. Fuse protected.
  • Internal fuse protection for all DC output voltages
  • Power input 115/230 VAC three prong plug.
  • Size (HWD) 2.73 x 5.41 x 8.18 in. (69.3x137.4x207.8 mm)
  • Weight 4.0 lbs (1.81kg).
