The Signal In Ports of the ADMA can be used as:
• Synchronization input to receive clock signals from an external data recording or measurement system to permit offline synchronization with other data sources.
Note: This input only registers one pulse per ADMA cycle. Additional pulses occurring within an ADMA cycle are ignored.
• External Trigger input to receive sporadic signals such as those from light barriers, alley entrance, brake pedal triggers, etc..
Note: This input only registers one pulse per ADMA cycle. Additional pulses occurring within an ADMA cycle are ignored.
• Analog input to measure analog Voltages.
• Event input to reset the ADMA distance travelled signal. (Available at IN3 only)
Functional description
The rising edge of the signal fed to the digital input triggers a time measurement. Therefore, it uses the last ADMA sampling time point as a reference. The occurrence of this event is indicated in the system status. The time values can be viewed in the data packet designated “Trigger times”.
