4.3 Hub
The PowerShield Hub is used to connect external sensors for measuring string current and ambient temperature and has
an on board ambient humidity sensor. Each Hub can read from one Current Transducer and up to two Ambient
Temperature probes. It also has two Dry Contact inputs that can be used to read the state of external devices.
The PowerShield Controller communicates with the Hubs via the Controller hub ports, connected using CAT5 cable. It
also supplies 24VDC power to the Hubs over this cable. Up to eight Hubs can be connected to a single PowerShield
Controller, 1 per Controller hub port. This allows up to eight strings to be monitored with one PowerShield Controller.
The Hub is also the BBus link between the PowerShield Controller and mSensors. The mSensors are connected to the
Hub using 4-core BBus interconnect cable.
Each Hub has a factory set ID number in the range 221 to 230. Hub ID 221 should be used for the first string and
subsequent sequentially numbered Hubs are used for multiple string systems (where applicable).
The LED on the Hub indicates Hub state. Refer to Appendix 2 for Hub LED behaviour.
