The model SC100 Wireless Switch/Contact Relay adds local output options to the alarming capabilities of our wireless data acquisition/logging systems and Model SC sensors. The SC100 provides a 10A/250V contact relay/ switch which is used in conjunction with our HaloCloud service alarm capabilities (text/email notification or contact relay output options). Individual sensor alarms can be programmed to use the Model SC100 wireless relay to trigger local alarm notification (light/beacon/buzzer/horn). The SC100 can also automate processes by adding control capabilities within the sensor network by turning on/off system parameters which directly provide feedback to measurements.


The SC100 Wireless Switch/Contact Relays are used in a broad range of facilities management and industrial process 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 additional industrial process control and automation capabilities.
