The DI-160 USB Event Data Logger features 8 input channels (four high and four low) with programmable capture modes to detect events (when the events happen), states (how long between events) and counts (how many events).

The DI-160 features programmable capture modes to detect events (when the events happen), states (how long between events) and counts (how many events). An internal real time clock provides time and date stamping for each captured quantity, and storage is accomplished to a removable SD-style memory card. Data storage format is comma-separated value (CSV) so recorded files are human-readable and easily imported to other applications like Microsoft Excel.

The DI-160 features eight input channels split between four high voltage and four low voltage types. The high voltage channels may be connected to any ±300V or 230 VAC rms source and feature input-tooutput and channel-to-channel isolation of 500 VDC or ±250 V peak AC. The four low voltage inputs are internally pulled-up and may be used to detect activity from switch closures, TTL-level signals, or DC levels up to 30 Volts.

The unit can be powered by an AC adaptor or an internal rechargeable battery. Three status LEDs are provided: USB interface detected, sampling, and battery charging.
