ENVIROMUX-1W features 2 RJ11 6P4C connectors for daisy-chaining 1-wire temperature/humidity/dew point, thermocouple, and digital input expanders in any combination.
Up to 24 temperature, thermocouple, or any single reading 1-wire sensor can be connected between both RJ11 connectors.
Up to 8 temperature/humidity/dew point combination 1-wire sensors can be connected between both RJ11 connectors. Each temperature/humidity/dew point sensor is equivalent to 3 single reading sensors.
Up to 12 ENVIROMUX-DI2-1W digital input expanders can be connected between both RJ11 connectors to allow a maximum of 24 additional digital inputs. Each ENVIROMUX-DI2-1W is equivalent to 2 single reading sensors.
Maximum cable length supported on each connector is up to 600ft (183 m) depending on the configuration and number of connected sensors.
Use RJ11 splitters (RJ11-3JCK) to daisy-chain 1-wire sensors (sold separately).
Single mode cables have a small diameter 9 micron core allowing one pathway of light. Multimode cables have two different large diameter core sizes 50 and 62.5 micron allowing multiple pathways of light.
The ENVIROMUX® Remote Power Reboot Switch allows you to remotely reboot and control power (on/off) to a server or other powered device over IP. The Easy-to-use web interface makes controlling power from anywhere in the world child's play.
