Digital/Event Data Logger

Data Recorders for Digital Signal, Events or Pulse Inputs

We offer several models of data loggers that are designed specifically for recording the state of digital inputs such as switch closures, relays or pulse output devices or which can record changes in the state of these inputs as a time stamped event. These units are generally the most cost effective event data loggers, for recording one or just a few signals.

We also offer General Purpose, Universal Input Data Loggers from a number of manufacturers that offer digital inputs in addition to analog inputs. These devices are well suited to applications that require logging a mixture of different signal types such as measuring a tank temperature or level and the state of a heater relay or fill valve.
