Some of BAPI’s ETA products require regulated power of 12 or 24 VDC, including the FOX – RS-485 Fiber Optic Transceiver and the RPTR – RS-485 Repeater. The 3312VC and 3324VC Voltage Converters can provide the 12 or 24 VDC regulated voltage required by the other ETA units. The 12 or 24 VDC output is field selectable via a jumper on the circuit board.

The 3312VC and 3324VC can be mounted in two ways.  In the first method, the units plug vertically into a BP4 or BP8 Backplane like a standard interface device. The voltage converter receives its supply power from the Backplane which is supplied by a PS17 – 33VDC Power Supply or other power supply.

The 3312VC and 3324VC can also be mounted in snaptrack. The unit is then powered with a two-wire connection from the PS17 – 33VDC Power Supply or other power supply.

If the 3312VC is powering a FOX or RPTR module, the 12 VDC output from the 3312VC is sent to a RBP – Communications Repeater Backplane or SRBP – Single Repeater Backplane. The Repeater Backplane then provides power, communications and mounting for the FOX and RPTR modules.
