D122 UniBlitz Shutter Driver

The UniBlitz D122 and T132 are capable of controlling all shutters in the UniBlitz line. The T132 incorporates two precise timers to control shutter exposure and delay interval. Each timer ranges from .1ms to 9999sec. Four digit push-wheel switches provide exceptional resolution for use in a multitude of shutter applications, ranging from photography to holography. The D122 drives the shutter while relying on the users input signal to determine exposure and frequency.

One feature of the T132 is the PRE or POST exposure delay. The PRE/POST toggle switch allows the user to actuate the shutter immediately upon receipt of a trigger signal or delay the EXPOSURE for a predetermined period. The period of the DELAY interval is determined from the front panel DELAY TIME SELECT. The DELAY signal is provided to an output (BNC connector) for the DELAY interval. In addition to the PRE/POST DELAY, the T132 can re-trigger itself continuously to provide a low-level chopper control. In the CONT. mode the DELAY interval control acts as the recycle interval to determine the exposure frequency. By using external control capability and this mode, exposure bursts can be controlled using the T132 EXPOSURE and DELAY timers. Set the T132 into continuous mode and trigger the system to begin cycling. By monitoring the pulse output the precise cutoff point can be determined and the unit can be reset without interrupting the exposure cycle.

One feature of the D122 is the selection of interrupt mode. With the mode switch in the A position, the unit will disable itself upon a AC line failure. When power is restored, the unit will remain disabled until reset. In the B position the unit will become disabled when a DC voltage level is removed from the interrupt input. When the input is restored, the unit will remain disabled until reset. The STD mode will bypass the interrupt capability. This mode selection makes the D122 more versatile for applications where the shutter must not reopen until acted upon by the user.

The patented driver design of the D122 and T132 allows any UniBlitz shutter including VS35) to be operated to its maximum frequency as specified in the shutter data sheets. Other features of the D122 and T132 include, automatic switching for 115VAC or 230VAC operation, controllable via RS232 interface, normally open or normally closed operation, selectable pulse energy switch for VS35 operation, convenient output for shutters equipped with electronic synchronization switch, and an external regulated +5VDC supply (T132 only - +8VDC unregulated D122).
