Low Voltage / Dry Contact Sensor (ELV2)
Requires the eGauge Sensor Hub and eGauge model EG4xxx (Pro or Core), not compatible with older model units.
Analog sensors require ≤ 50Ω output.
Only use straight-through RJ-11 cables to connect powered sensors to the Sensor Hub. Telephone systems generally use "reverse" style RJ-11 cables which are incompatible with the Sensor Hub. See this article for more information on verifying the correct RJ-11 wiring. Every Sensor Hub compatible sensor sold by eGauge Systems comes with a straight-through RJ-11 cable.
The eGauge 2V Analog Input is used in conjunction with the Sensor Hub and an EG4xxx model meter (Core or Pro) which allows EG4xxx meters to read 0 -- 2V low-impedance analog values or states from standard 2-wire dry contacts such as relays.
