The SC8 External Jack Sensor is our base level external sensor device. It includes the same functionality of the SC18 except with a reduced wireless range and non-upgradeable firmware. It accepts up to 4 individual external sensors at one time. We offer a selection of AC Current (CT) sensors ranging up to 200A and compatibility with 3rd party plug type sensor providers. Our DataRecorder and configuration utility software can be programmed to display the proper measurement units for the individual sensor inputs.

Schneider Electric, Veris Industries, Onset, and other manufacturers also offer a range of compatible sensors including air pressure, CO2, 4-20mA, 0-10V, and more. Remote email or text (SMS) alarms can also be enabled with our HaloCloud service.
