El USB 5

This stand-alone data logger can record events (detecting an input and storing the time and date), 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 during a timed interval). Over 32,000 events or state changes can be recorded, or over 32,000 timed intervals in count per mode (with up to 65,000 counts per interval) for the EL USB 5.

Over 1 million events or state changes can be recorded, or over 1 million timed intervals in count per mode (with up to 65,000 counts per interval) for the EL USB 5+.

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). The logger can record events at speeds of up to four times per second and state changes at speeds of up to two times per second. In counting modes the logger can operate at speeds of up to 100 counts per second.
