Regular price $80.00


The CONTACTlogger time-of-use data loggers, part of the SMARTlogger Series, are designed to monitor the on/off status and total time-of-use of switches and relays on un-energized, "dry contact" devices. It is equipped with a 3-foot (90 cm) pair of wires that are connected to the switch or relay. When they make contact, an "on" transition is recorded.

Powered by a user-replaceable coin cell battery, professional installation is not required to use these small, robust loggers. No electrical connections are required to power the logger.

Up to 32,000 records are stored in internal memory. Data can be downloaded to a PC using SMARTware software and a USB communication cable (purchase here: SMART-COM-CBL). One cable is required to connect the logger to a PC.

Each SMARTlogger provides powerful data for superior energy management.
