3312VC - Voltage Converter
Electronic Technician Assistant (ETA)

  The RS-485 communications repeater (RPTR) and the fiber optic transceiver (FOX) require 12VDC power. The 3312VC converts the 33 VDC from the power supply fuse block (PS17) into the 12 VDC required by the RPTR and FOX.
   There are two mountings options for the 3312VC. The 3312VC can plug vertically into the interface module backplanes (BP4 or BP8) like a standard interface device. A 2-wire cable then connects the 12 VDC power to the communications repeater backplane (RBP) which powers the RPTR and FOX. The 3312VC can also fit directly into the snap track plugging directly into the RBP so that the BP4 or BP8 is not required. The unit can then be powered with a two-wire connection to the PS17 or any standard 24 VDC power supply.

All good projects need a proper foundation and the ETA modules are no exception. The TRK18 - Snaptrack provides a sturdy, secure and easy mounting method for the ETA line.
BP2, BP4 or BP8 - Interface Backplane
The BP2, BP4 and BP8 Backplanes provide a convenient way to mount and power the BAPI ETA interface devices which helps cut down on control panel and control room clutter. Connectors on the face of each Backplane plug into mating connectors on the ETA modules. The BP8 accommodates eight modules while the BP4 accommodates four modules and the BP2 accommodates two modules.

RBP - Communications Repeater Backplane RBP - Comm. Repeater Backplane
The RBP - Communications Repeater Backplane fits into the TRK18 snap track and distributes power and communications and provides convenient mounting for the FOX and RPTR modules.
Mixing/matching FOX and RPTR modules on the same RPB allows the 485 bus to be branched in the telephone equipment room or communications closet.
