Stand-Alone, 8-Channel Event, State, and Count Data Logger

DATAQThe DI-160 is a stand-alone event, state, and count data logger that features four programmable measurement modes. The data logger enables you to determine when events occur, the total number of events, and the period of time in between events. It can count parts by monitoring a proximity sensor’s pulse output, or determine a machine’s downtime by monitoring AC power.

The DI-160 includes eight channels. Four ±300-VDC/peak AC isolated channels can accommodate high-level DC voltage signals, pulse inputs up 2 kHz, or AC line voltage. Four ±30-VDC/peak AC non-isolated channels (pulled high) enable you to monitor lower-level DC voltages, TTL-level, signals, or switch closures.

You can use DATAQ’s Event Recorder set-up software, which is included with the data logger, to enable/disable channels, select measurement modes on a channel-by-channel basis, and choose one of 21 sample intervals, ranging from 1 s to 24 h. Data is stored to a removable SD memory card in CSV format, enabling up to 500 days of continuous recording and easy viewing in Microsoft Excel.

The DI-160’s AC channels provide channel-to-channel and input-to-output isolation up to 500 VDC (±250-V peak AC) and have a 4-V trigger threshold. The low-voltage channels are protected up to ±30 VDC/peak AC and trigger at 2.5 V.

A built-in rechargeable battery acts as a “bridge” when disconnecting the data logger from a PC and connecting it to the USB power supply. Three LEDs indicate when the DI-160 is actively acquiring data, when the unit is connected via USB to a PC (or the included AC power supply), and the battery’s charge state. A push button enables you to start and stop recording to the SD memory card.

The DI-160’s four selectable measurement modes. State mode determines an event’s duration. Event mode detects a single change of state (within a sample interval). High-Speed (HS) Counter mode yields the total number of state changes within a sample interval. AC Counter mode counts the number of times AC power turns on/off within a sample interval.

The DI-160 costs $299 and includes a mini screwdriver a 2-GB SD memory card, an AC power supply, and a mini-USB cable. The DATAQ Event Recorder software is available for free download.
