24 VDC Power Supply Input, J9
An external 24VDC power supply is required to power the Turbo PMAC2 Eth Ultralite. The 24V
is wired into connector J9. The polarity of this connection is extremely important. Carefully
follow the instructions in the wiring diagram. This connection can be made using 16 AWG wire
directly from a protected power supply. In situations where the power supply is shared with other
devices, it may be desirable to insert a filter in this connection.
The power supply providing this 24V must be capable of providing an instantaneous current of at
least 900 mA. In the case where multiple devices are driven from the same 24V supply, it is
recommended that each device be wired back to the power supply terminals independently
The connector for J9 is a Phoenix PCB Edge connector ZEC 1,5/ 3-ST-5,0 C2 R1,3 with Delta
Tau part number 014-188305-001 and Phoenix part number 18883051.

MACRO Connector
Based on the option that you have, either the MACRO fiber connector or the MACRO RJ45
connector will be installed on the controller.
Option A provides the MACRO-ring fiber optic SC-style interface connector. The key
component on the board is U49.

1. The fiber optic version of MACRO uses 62.5/125 multi-mode glass fiber optic cable terminated in an SC-style
connector. The optical wavelength is 1,300nm.
2. It is possible to "adapt" wire to fiber operation when using OPT B.
