Information
The DD 501 Digital Delay is an events counting Plug-In unit
designed for use in a TM 500-Series Power Module mainframe.
Separate external trigger signals are connected to the
EVENTS and START INPUT connectors which allows up to 99999
events to be counted. The Plug-In unit counts a
predetermined number of events, from 0 to 99999, which are
selected by the front-panel thumb-wheel switches. The last
event counted generates a trigger pulse to the DLY’D TRIG
OUT connector on the front panel.
