The Model SC101 Wireless Relay with Current Sensor adds a built-in A/C current sensor, which can monitor the power usage of a controlled load, to our control relay capabilities. The current sensor allows relay controlled loads to be monitored for correct operation, power consumption, and other power data. As an option, our Model SC111 offers a standard NEMA-3 plug connection.

The SC101's local relay output option adds alarming and control capabilities to our wireless data acquisition/logging systems and Model SC sensors. The SC101 provides a 10A/250V contact relay/ switch which is used in conjunction with our HaloCloud service alarm capabilities (text/email notification and/or contact relay output options).

Individual sensor (Model SCXXs) alarms can be programmed to use the Model SC101 wireless relay to trigger local alarm notification (light/beacon/buzzer/horn). The SC101 can also automate processes by adding control capabilities within the sensor network by turning on/off system parameters which directly provide feedback to measurements.

Wireless AC Load monitoring with Relay Controled Loads are used in a broad range of facilities management and industrial applications in the energy management, food handling and processing, medical/pharmaceutical, petrochemical and agricultural industries among others. Typical applications include local alarm condition notification, lighting control, energy efficiency systems and a broad range of industrial process control and automation capabilities.
