Get Accurate Runtime Data Instantly

The RX Runtime Smart Sensor measures the percent ON of any AC-powered device with an AC current switch, and time ON (closed) of contact closures – ideal for equipment runtime monitoring, boiler efficiency monitoring, pump monitoring, and engine monitoring.

This sensor is compatible with HOBO RX Stations.

Features

• Plug-and-play smart sensor
• Works with all HOBO RX stations
• Automatically communicates configuration data to the station
• 1-second runtime resolution
• 6m cable length

 

Input Sampling Period	1 second
External Contact Input	Solid state switch closure, logic driven voltage output, or open/closed mechanical switch
Preferred Switch State	Normally open
Solid State Closure	Input Low: < 10 KΩ; Input High: > 300 KΩ
Logic Signal Level	Logic 0: < 0.4 V DC, Logic 1: > 2.5 V DC
Internal Weak Pull-Up	100 KΩ
