Lascar EL-USB-5 Counter, Event & State USB Data Logger

The Lascar EL-USB-5 is a Standalone Data Logger that 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).

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.
