Low Voltage / Dry Contact Sensor (ELV2)
Visit the online store page
Model: 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.

Assembly/installation information
- It is not advisable to extend the RJ11 leads from the Sensor to Sensor Hub. It is acceptable to use a longer RJ45 cable from the Sensor Hub to the eGauge.
- If RJ11 cable between Sensor and Sensor Hub must be extended, it is advisable to use twisted pair wires, such as a CAT5 cable with RJ11 plugs (most commonly used for DSL modems).
- If terminating own cables, both RJ11 and RJ45 cables should be straight-through cables, with the same color order on both ends.
- Install the sensors and Sensor Hub.
- Connect the ELV2 to the 0-2V sensor output using the signal and ground ports on the ELV2. The 5V pin is unused.
- Configure the sensors.
