The DI-161 LAN-based Event Data Logger features 8 input channels to detect events (when the events happen), states (how long between events) and counts (how many events).
In general applications the DI-161 acts as a state change and on/off data logger. Examples include the reporting of activity involving motors, pumps, fans, refrigeration units, flow sensors, and more. In a more narrow sense the DI-161 can develop a complete picture that describes all the variables needed to quantify overall equipment effectiveness (OEE). For example: Actual operating time; Actual production rate; Total units produced; Defective units produced.
In many applications a range of existing control signals may be paralleled with the DI-161 to derive desired OEE metrics. For example, if power is applied to a machine whenever it is available for production, that same signal can be applied to a DI-161 channel and configured for the "State" mode to allow the DI-161 to report Actual Operating Time. Likewise, a sensor that produces a pulse when a completed part is ejected by a machine can be applied to a channel configured for the "Count" mode to derive Total Units Produced and Actual Production Rate. The flexibility of the DI-161 allows a wide range and combination of measured metrics.
