The Rain8upb is a modular 8-zone sprinkler controller module that can be an integral component of any UPB installation. It is capable of driving standard 24VAC irrigation valves directly.
The master module is the first 8-zone module in a UPB installation and the only one that connects directly to a PIM and a 24VAC transformer. Additional modules may be daisy chained for those large installations.
There is a single RS232 connection between the UPB PIM and the Master Rain8.
The 24VAC power and network communications are transferred from master to slave-to-slave etc.
The network connection for the slave units is an 8 conductor RJ45. Each slave has a pair of these modular jacks to pass on data and power to the next one in a daisy chain. Each slave also has a RS232 connection that is used only to assign the address and setup default run timers during the initial configuration.
Package includes:
Rain8upb master module 110 to 24-vac, 20VA, transformer
3 piece RJ11 to DB9 cable assembly
Not supplied but required for operation: A UPB power line interface (PIM) (PCS PCPIMR, Simply Automated SAUMCDB9 or HAI HA36A001)
You will need a PC with Windows 98 or later as your operating system, a serial port or USB port and the supplied RS232 RJ11 to DB9 cable.
Optional default run timer for each zone to prevent over watering
Optional dry contact input for rain sensor or pulse type flow meter
