This article contains PDF files with circuit diagrams to create EVENT input circuits to DTS DAS. The circuit descriptions and component part numbers are detailed in the attached files.
Event - 5V Hi-Lo
To convert a falling edge logic level to trigger TDAS, TDAS G5, or SLICE DAS. The components are chosen to eliminate time delays that can occur when using opto-couplers. This circuit converts the voltage input to a contact closure. The 5V level must be active high to allow the DAS to 'arm'.
Event - Normally Closed to Normally Open Converter
TDAS, TDAS G5 and Slice PRO DAS nominally need a closed circuit trigger input in order to trigger externally. This circuit allows the user to connect an input which goes open circuit not closed circuit on a valid trigger. It is especially useful for blast test applications.
