Counter, Event and State USB Data Logger
- Accepts input voltage up to 24V
- Volt free contact option
- Rising and falling edge triggering
- Connection via screw terminals
- USB interface for setup and download
This standalone data logger can record events (detecting an input and storing the time and date of occurrence), record state changes (similar to an ‘event’ but also recording when the input reverts back to normal) and count events (count the number of events that happen in a time period, without any individual event time or date information). Up to 32,510 events or 32,510 state changes can be recorded.
Events and state changes can be triggered by either a rising edge (a voltage going from low to high) or falling edge (a voltage going from high to low). It is also possible to use volt free contacts. Instead of measuring an external voltage, the data logger applies a voltage across the screw terminals and detects when the input closes (i.e. a relay or microswitch).
Fast logging rates allow event capturing at speeds of up to two times per second and state changes at speeds of up to five times per second. Event counting can operate at speeds of up to 100 times per second (when the LEDs are turned off). The user can easily set up the logger, and download the stored data by plugging the data logger into a PC’s USB port and running the purpose designed software under Windows 2000, XP, Vista & 7. Data can then be exported to other applications for evaluation.
The data logger is supplied complete with software, measurement leads terminated with crocodile clips and a long-life lithium battery which allows logging for up to 1 year. Functionality of the unit is indicated by flashing red and green LEDs, with an option to flash the red LED every
time an event occurs.
